Description

Anti-vibration tube bracing or strutting arrangement

Technical field

The present invention relates to be commonly referred to the pipe bracing or strutting arrangement of pile tube.Install this pipe bracing or strutting arrangement with control flow the vibration cause and prevent pipe or bar mobile in bundle.Can improve this pipe bracing or strutting arrangement for the tube bank or the bar bundle that exist or be installed in new intrafascicular.The present invention is effective to heat exchanger, cooling tower, steam generator with tube bank in the similar fluid treating plant.Expection the present invention can be used for flowing through any application that the caused vibration of pattern of elongate member (pipe, pipeline, bar or the like) has problems by fluid.

Background technology

Be organized in intrafascicular pipe such as the tube bundle devices of shell and tube exchanger and the similar object utilization of fluid treating device, pass through equipment with the guiding fluid.In this tube bank, fluid flows through the inside of pipe usually and flows through the outside of pipe.The structure of intrafascicular pipe is by the tube sheet setting, and pipe is arranged in this tube sheet.A kind of common structure that is used for pipe is a rectangular array, and wherein pipe is arranged among the row of alignment, has the piping lane (straight line path between the pipe) of mutual vertical alignment between every pair of pipe or pipe row.In this array, except that the periphery of tube bank, each manages contiguous eight other pipes and crosses piping lane directly relative with respective tube, and piping lane makes its row separate with two adjacent rows.In triangular tube formation, the pipe among the staggered row is in alignment with each other and becomes to make contiguous six other pipes (two adjacent tube are in identical row, and four pipes are in two adjacent rows) of each pipe.

Can the generation in tube bank the flow vibration of the vibration character that causes of the change of the fluid flow pattern around the pipe and fluid temperature (F.T.) that occurs when fluid circulation time in heat exchanger and density.If these vibrations reach certain critical amplitudes, but halved tie produces damage.If the pipe with different materials in heat exchanger is changed initial pipe, for example change relatively hard materials with lighter weight pipe, vibration problems may worsen.When placing stricter operation, equipment requires following time, for example, and when the device upgrade of other existence and previous gratifying heat exchanger become when being flowed the vibration that is caused the also vibration that may flow and be caused under New Terms.Even when interchanger still is in the fluid stream but does not conduct heat, also may produce vibration in some cases.

Except that good equipment design, can take other measure to reduce tube vibration.Pipe bracing or strutting arrangement or be that known (with reference to this specification) can be installed in tube bank as the pile tube of these bracing or strutting arrangements, the vibration that caused and prevent excessively moving of pipe so that control is flowed.Many pipes support or pile tube has been suggested and has obtained commercial.One type that describes in the U.S. Patent No. 4,648,442 of authorizing Williams has U shape structure, and wherein the distance between the adjacent row in the upper surface of passage and the distance between the lower surface and the tube bank equates (promptly equating with the piping lane size basically).This stake is inserted between the intrafascicular row and in the end to be fixed by arcuate section, and this arcuate section engages the part of the pipe of tube bank periphery, so that the appropriate location between the row in its tube bank is locked in the appropriate location with stake.Such stake typically by corrosion resistant metal (for example, thickness be 0.7 and 1.2mm between 304 type stainless steels) make, thereby, be inserted in the corridor between the intrafascicular pipe to allow stake for the tube bank that stake is housed provides necessary rigidity and the enough elasticity in the U shape passage.

The vibrationproof pile tube of another kind of form has been described in the U.S. Patent No. 4,919,199 of authorizing Hahn, this patent disclosure make the stake of the band of soft V structure, wherein saddleback forms perpendicular to the longitudinal axis of band at the end place that opens of this V-arrangement cross section.Saddleback forms on tape, and its spacing (distance between the saddleback) equals tube pitch, and the radius of the pipe in its radius and the tube bank matches, so that saddleback engages with pipe on a side of piping lane.Joint between these pipes and the saddleback is locked to appropriate location in the tube bank with pipe.Effective overall width of stake is opened and reduced to the elasticity of band with the spring type effect associating that is provided by the V structure, the arm of permission V, stake can be engaged, so that the stake of V shape is locked to the appropriate location between two combs on the both sides of piping lane with pipe.

The pile tube of similar type has been described in the U.S. Patent No. 5,213,155 of authorizing Hahn, this U.S. Patent Publication the stake of a kind of U shape, this U shape stake is inserted between two piping lanes, the blind end of U is on one of them intrafascicular peripheral tube.Saddleback is formed on opening on the end of V-arrangement cross section, to engage with the opposite side of pipe among the intrafascicular single row.The stake of U shape is fixed on the pipe appropriate location on every side of bundle by the suitable fasteners of extending between two arms of stake.

U.S. Patent No. 4,648, a problem of the extrusion structure of 442 shown types are, though stake is locked into the appropriate location in the piping lane of its selection, stake can not produce active position for each single pipe.Maintenance free vibration in Guan Zaiyu piping lane and the parallel plane of stake.U.S. Patent No. 5,213, there is different problems in design shown in 155: though the pipe among the row who is centered on by the stake of U shape is fully supported, but, directly do not surround by one of them, the pipe (these pipes are the outer tubes among the staggered row who is not surrounded by the end of U-shaped stake) that promptly remains on the tube bank periphery in one of them blind end of U-shaped stake can move freely, and can expect vibration in these pipes under certain condition.In addition, because the fold that pipe supports had transitional region before arriving its complete degree of depth, so two pipes of contiguous each outermost tubes are not accepted any Vibrant buffer.

Use the passage stamping parts to be, when the relative broad of piping lane, need dark passage stamping parts or other essential measure with the shortcoming that the stake of holding the distance between the pipe that forms single piping lane designs.A kind of pipe of complicated form more supports and is illustrated in the U.S. Patent No. 6,401,803 of authorizing Hahn.Two V shape stamping parts are used in this stake, and this stamping parts is separated by the compression spring, and this compression spring forces the pipe of stake on the opposite side of piping lane, vibrates so that suppress.Yet the manufacturing of this stake is quite expensive.Therefore still need to hold relative broad piping lane and do not make the whole stake of partitioned portion complexity.

Description of drawings

To describe the present invention in conjunction with the accompanying drawings now, similar in the accompanying drawings Reference numeral is represented similar key element, wherein:

Fig. 1 is the schematic diagram that the anti-vibration tube between four pipes in the rectangular configuration heat exchanger supports that is arranged in according to the embodiment of the invention;

Fig. 2 is the schematic diagram of the modification that supports of the anti-vibration tube of Fig. 1; With

The schematic diagram that Fig. 3 supports for the anti-vibration tube that is arranged in according to another embodiment of the present invention between three pipes in the triangular structure heat exchanger.

The specific embodiment

Arrange pipe bracing or strutting arrangement of the present invention or pile tube, thereby for located adjacent one another but be positioned at pipe on the opposite side of piping lane (tube lane) or bar or conduit direct support is provided.Pile tube can be along between the pipe in the piping lane insertion tube bank between the adjacent tube row.Expection pipe bracing or strutting arrangement can insert in the piping lane in the existing tube bank.Be formed on a certain amount of bending that fold in the pile tube allows pile tube, making that stake can enter may be because the warpage of pipe or slender member and the piping lane that not limit clearly.Be expected at equally during the assembling tube bank, the pipe bracing or strutting arrangement can be positioned in the piping lane.Though the present invention is described in connecting pipe or tube bank, does not mean that the present invention only uses with the cylinder type hollow pipe.Meaning is sought for, and the present invention can use with hollow or solid bar or pipe.In addition, this pipe is not limited to circular cross-section; But wish that this pipe can be square, triangle or other structure.Under the situation that the structure of interchanger allows, stake can be made into long enough extending to opposite side from restraining a side, thereby provides support for the pipe of the whole width that strides across bundle; In this case, the length of pile tube will change according to the length of the piping lane that strides across bundle.Yet in many cases, the position of intrafascicular vestibule (pass lane) will produce discontinuous in the corridor, insert stake thereby can not stride across bundle always.In this case, can from different perspectives stake be inserted in the bundle, so that provide support as much as possible for pipe along the length of bundle.Therefore, this will be in direction (with different angles in the transverse plane of pipe) the laterally inserted bundle of each axial location with variable-angle, and described direction can change angle from the direction of insertion of the axial adjacent position of the next one.Yet this may make pipe in the some parts of bundle, does not usually have stake to support at the middle part that hinders the bundle that enters from periphery.In view of its simple and repeat structure, the length that can easily current pile tube be cut into hope is to cooperate bundle, no matter its part that extends fully through this route or only extend this route.Extra if desired rigidity can be tied stake around the periphery of tube bank, and for example, the end bending by making stake to be to form lug, and then, this lug can be riveted or otherwise be locked on the shroud around tube bank.This for example can utilize rope or other suitable fixture to be fixed together.This rope can enter by the hole in the end of pile tube 10 17.

Fig. 1 and 2 is illustrated in four adjacent tube A, B, C and D in the tube bank with rectangular tube formation.In spacer lane or piping lane L between pipe bracing or strutting arrangement of the present invention or pile tube 10 insertions two combs.Pile tube 10 can be formed by metal tape or other suitable material that can stand owing to being exposed to the corrosion that fluid in the heat exchanger and temperature produce for a long time.Pile tube 10 extends in piping lane L, and this piping lane L is by limiting at the pipe A of a side of corridor and D and at the pipe B and the C of the opposite side of piping lane.Certainly, the other pipe that in complete tube bank, extends in the row of existing in, this row is formed by the continuity that comprises the pipe row who manages A, D, and another row is from pipe B and C continuity, and other pipe row is to form the similar traditional approach layout of tube bank.Piping lane between two adjacent rows of this of pipe and other adjacent row will similarly stride across tube bank and extend.Pile tube 10 has the pipe engaging zones 13,14,15,16 that is formed by transverse corrugations, and this transverse corrugations is extended alternately from two faces of band.First group 11 of transverse corrugations extends engaging with pipe A and B from the face 10A of band and 10B, and second group 12 of fold from the face 10A of band and 10B extend with manage C and D and engage.Continuous group of fold will be formed on along on other position of the length of being with, thereby the corresponding position of relative with other in a similar manner Guan Zaiqi engages.As shown in Figure 1, in first group of fold, the pipe bonding part is formed by most advanced and sophisticated or terminal 14A, the 14B on most advanced and sophisticated or terminal 13A, 13B and the opposite side 10B of the fold on the side of band 10A.Most advanced and sophisticated 13A, 13B engage with pipe A, and most advanced and sophisticated 14A, 14B engage with pipe B.Adopt similar mode, most advanced and sophisticated 15A, 15B engage with pipe D, and most advanced and sophisticated 16A, 16B engage with pipe C.Though at Fig. 1 two tips or end are shown, the present invention is not that intention is limited to this; On the contrary, expection can provide at least three ends or tip (for example, as shown in Figure 2,13A, 13B, 13C).

Same expection tapers off to a point or terminal fold can be extended on the whole length of pile tube 20 basically, as shown in Figure 3.Same expection fold can only be extended along the part (for example outside) of stake.This fold can combine with other device, described other device for example, authorize " Anti-Vibration Tube Support " U.S. Patent application No.10/848 by name of people such as Wanni, disclosed in 903, the content of this U.S. Patent application is incorporated by reference at this.For example,

Transverse row at the pipe engaging zones of placing projection on the pile tube will provide the joint of hope between pile tube of restraining and pipe, utilize it can use tube bank.In order to hold vestibule in tube bank, the distance between continuous group of fold can correspondingly strengthen or reduce, thereby consistent with the layout of intrafascicular pipe.Expection fold can be extended on the whole length of pile tube 20 basically, as shown in Figure 3.This layout is especially effective when spacer lane or piping lane are not clearly limited.

Typically, fold from a tip to most advanced and sophisticated relatively total depth be 0.5 to 2mm, be preferably 0.5 to 1.5mm, this total depth is greater than the interval between pipe junction point pipe, so that realize the pipe deflection of similar scale at this some place.Expect that the height of each fold can change.Because pipe is inserted in the paddy portion of fold to a certain extent, as shown in drawings, wherein for example manages A and be inserted in paddy portion between most advanced and sophisticated 13A and the 13B, so the accurate deflection that is in fact realized will be less than the total depth of stake.Significantly, pipe holds the degree that degree to the paddy portion and pipe be seated most advanced and sophisticated top will depend on corresponding geometry, comprise the pipe diameter, tube shape, spacing and at interval and the fold spacing (distance between the continuous tip in a group) and the degree of depth.This can determine based on experience best.Therefore, to a certain extent, the pipe engaging zones that forms by fold will be engaged in pipe around, make most advanced and sophisticated distance can not represent the separation that will cause in the pipe exactly to the tip, but find that usually this fold degree of depth will be suitable for producing the pipe deflection, support that this pipe deflection provides and vibration resistance also obtain very firm tube bank.When the fold elasticity of stake itself and elasticity of pipe when being out of shape around pipe, in conjunction with engaging between protruding pipe engaging zones and the pipe, will not only make and manage more antivibration, and make in intrafascicular maintenance appropriate location.Expectation be, select the total depth (tip that comprises tape thickness is to most advanced and sophisticated distance) of pipe engaging zones, make each make the Guan Congqi inoperative position deflection that is supported with about 0.5 to 2mm microtubules deflection usually.This is the feature of the stake of current type, and this allows to use and is less than common stake number, usually, lacks about 50% than the needed quantity of alternate manner.An advantage of the pile tube of current type is, because only about half of piping lane size is occupied on each side of band, so at the piping lane that can not hold relative broad deeply under the situation of pressure zone.

Except that the total depth of stake, thickness and the rigidity of inserting the material of intrafascicular time band when stake will be as the factors of determining last pipe deflection.Usually, 1 to 2 millimeter tape thickness will provide enough pipes to support and resist the ability of inserting intrafascicular stress satisfactorily.

Fig. 1 and 2 illustrates the pile tube 10 that is in the appropriate location in the rectangular tube formation, and this pile tube is fit to this structure preferably.Pile tube 10 also can be used in the triangular structure.Fig. 3 illustrates the pile tube 20 that is in the appropriate location in the triangular tube formation.Layout shown in Figure 3 is suitable for pipe preferably needn't the evenly distributed maybe application when the interval variation between the pipe.Expection stake 10 or 20 can be used in rectangular configuration or triangular structure, thereby as long as the contiguous pipe of at least one of fold or a plurality of contact provides support for adjacent tube.

Because the effective clearance between the pipe (piping lane size) is less than the effective clearance of rectangular array in triangular tube formation, so (peak portion is to paddy portion for the total depth of fold, comprise plate thickness) and plate thickness will be typically less than the fold total depth and the plate thickness of rectangular arrangement, enough pipes support and stake keeps but the pipe deflection of equivalent is suitable for.Adopt above-mentioned the same manner, pile tube can insert in the piping lane between the pipe and be pushed into or draw in the appropriate location, and up to engaging with pipe on the piping lane both sides, the maintenance of stake is kept by the pipe engaging zones in metallic spring and the stake.

When the pipe supporting pile inserted tube bank, the fold that forms the pipe engaging zones must be pushed over or be pulled through pipe, is in intrafascicular appropriate location up to stake.Spreader bar can be used to temporarily increase the space between the pipe, to help to insert stake 10 or 20.Each set of corrugations must be pushed over or be pulled through the gap that is formed by piping lane, is in the appropriate location up to stake.Because the tension force in the stake will tend to fold is flattened, make stake more easily slip in the intrafascicular appropriate location, so for such stake, it is effective choice that the appropriate location is drawn in stake.Then, when tension force discharges, stake will return to its initial configuration, and fold is incited somebody to action in a predetermined manner conjugation tube tightly.For the ease of pipe is drawn in the appropriate location, band can be at one end or two ends be provided with and be used for the device with elongated tensioning apparatus of interim splicing tpae, this tensioning apparatus can insert between the intrafascicular pipe and with the engaged at end of band; Then, stake can be drawn in the following of bundle and be in its precalculated position up to stake, this moment, tension force can unclamp and tensioning apparatus breaks away from from band, made fold its initial configuration that relaxes back, remained on the pipe closely.With on engagement device may suitably be band the end hole 17 or be formed on the uncinus of the end of band by crooked end.Tensioning apparatus may suitably be pull bar with hooked end or the line that for example can engage with stake by latch, so that stake is drawn in its tram by this bundle.Can have L shape end suitably to engage with uncinus on the end of band as the tensioner rod of pulling device, perhaps alternatively, wire loop can pass hole in the band to apply pulling force when restrainting when entering in stake.Because the total depth (most advanced and sophisticated to most advanced and sophisticated, comprise plate thickness) of pipe engaging zones preferably is slightly larger than the width of piping lane, thus manage must slight curvature to allow fold pass through; Though this makes stake maintain the appropriate location when stake is in its final position, owing to must overcome the resistance of the bending of every comb, this makes and inserts difficulty more.The stake of using with rectangular configuration is general than the easier insertion of using with triangular structure of stake, this is owing to compare with first kind of stake, second kind of stake has littler at interval fold on the length of edge stake, and as transverse corrugations, they tend to allow stake in the insertion force that is applied to the outer end with from the far-end of stake and insert along it under influence of resistance of length and eject together; Apparently, insert when intrafascicular when stake, described problem further increases the weight of.Yet, the spreader bar that have sloping edge by at first inserting, thickness is slightly larger than the total depth (comprising fold or other elevated regions) of stake, after this, the appropriate location is inserted in stake and slowly remove metallic rod, can be convenient to pile tube is inserted tube bank to guarantee suitable locking at pipe and pile tube.This bar can be used in a similar manner so that remove this stake equally.

Transverse corrugations can with such as dimple, vertical fold, other pipe engaging zones combination of dimple/fold that merges or saddleback, described dimple, vertical fold, dimple/the fold that merges is described in the common unsettled U. S. application of No.10/848903 as the sequence number of authorizing people such as Wanni of " the Anti-Vibration Tube Supports " by name that submit on May 19th, 2004, the content of this U. S. application is incorporated into by reference specially at this, described saddleback is as the common unsettled U.S. Patent application No.11/128 that authorizes people such as Wanni of " the Anti-Vibration Tube Support " by name that submit on May 13rd, 2005, described in 884, the content of this U.S. Patent application is incorporated into by reference specially at this.Vertically fold may be particularly useful in dark tube bank, and in dark tube bank, stake must be inserted more relatively pipe, the wherein corresponding increase of pipe/stake active force during inserting.Use vertical fold can push stake or draw in intrafascicular more easily at the inner end of stake, and when transverse corrugations finally is positioned at the neighboring of bundle with respect to pipe, the transverse corrugations at place, the outer end of stake will make it remain on intrafascicular precalculated position.For this stake, owing to when not existing recess to restraint between the end of contiguous fold, stumble pipe to enter in stake, so thereby in fact can make vertical fold be convenient to stake continuously along its length inserts intrafascicular.Then, the transverse corrugations by the stake outer end keeps stake.Preferably arrange fold, make them stride across band wrongly and extend, as described in former application from each hand-deliver of being with.If tube bank is inserted in such stake under tension force, the temporary joint device that is used for tensioning apparatus will be positioned at this end of band.

Stake can be inserted by on the determined axial location of the vibration research of experience or relevant device.This can insert in the bundle with different horizontal directions at different axial locations according to staggered mode in succession in continuous axial positions along the length of tube bank, for example at first axial location with vertical direction, at second axial location with horizontal direction.This stake can be inserted in the bundle, is pivoted into the position of hope then.

As from accompanying drawing as can be seen, each pile tube engages with pipe on the opposite side of piping lane, makes that two combs within the neighboring that is inserted as tube bank of the stake in each piping lane provide support.At the periphery of bundle, some Guan Kecong on opposite side not the stake of stay pipe accept support.This reduction gives effective support of those pipes, but because the length of the extended stake of the last pair of pipes in restraint is relatively short, so the cantilever end by stake provides some effective supports for these outer tubes on a side at least.As mentioned above, utilize the end of lanyard stake 10 or 20 to improve the effective support that offers near the pipe in an end.

Though provide being frictionally engaged between stake and the pipe in the bundle for stake is remained on, the end of pile tube can have the pipe engage hook, recall along a direction to prevent stake so that on a side of piping lane, hook the end of pipe.Alternatively, stake can be folded into U-shaped or hairpin structure, and this U-shaped or hairpin structure have a pair of stake that at one end connects by arc pipe bonding part effectively.This structure can be simultaneously for three pipe rows or four pipe rows provide reinforcement, the extra active position that wherein is used for stake is locked to bundle from the shutdown side (arcuate segments) of hair clip an end.Because each stake is arranged for three pipes simultaneously or four pipe rows provide reinforcement, so the U-shaped pile tube will insert staggered row, be used for to each the pipe row in the tube bank provides reinforcement, or the U-shaped pipe is inserted into and makes it cross over staggered corridor between two tubulations and the row of being inserted into, this U-shaped pile tube will support four adjacent rows.If necessary, utilize retaining member can provide extra stake to keep, this retaining member is such as being in the bolt that extends between the arm of hair clip in the one or more positions along hair clip length.Be connected to around the metal shroud or the rope of tube bank by end, can be the single line stake extra locking (not forming the U-shaped structure) is provided stake.This stake can be fixed to band by form lug on the end of band, this lug can weld, rivet or be pinned to screw and be with; Alternatively, can go out crack or hole in the end of stake, shroud can pass through this crack or hole.Shroud can be fixed to tie-rod for example to reduce the possibility that pipe supports the landing pipe, this tie-rod is available in the tube bundle device of the outer tube periphery that is adjacent to tube bank.

Pile tube is suitable to be made by metal or other suitable material, and this material will opposing corrosion in the environment of the tube bundle device that uses this material.Usually, for opposing corrosion in water and other environment, stainless steel will be gratifying.When two phase stainless steel when being preferred, except that chloride corrosion took place in expection, Stainless SS 304 was suitable.The two phase stainless steel that comprises alloying element chromium, nickel and the optional molybdenum of various quantity is characterised in that, the mixing microstructure that ferrite and austenitic ratio approximately equate (therefore being referred to as " two-phase " usually).

Except that good stake hold facility, the another kind of major advantage of the stake of current type is a simplification.With the U.S. 4,919,199 and 5,213, stake shown in 155 is different, and it need receive saddleback by vertically being pressed into U shape or V shape passage along both direction and laterally pushing to form to manage, thereby forms metal tape, to need expensive operation for big machine, pressure can reach 20 tons in big machine.On the contrary, the pipe engaging zones of current stake can be formed by the single extrusion operation along horizontal direction, in the simple extruding of low-pressure, thereby by along the continuously extruded plurality of rows fold of making simultaneously of length.Certainly, use two pressure rollers to provide most economical selection, but it is optional, and uses more cheap, simpler equipment can not obtain bigger resource for extensive the manufacturing.

It should be apparent to those skilled in the art that under the situation that does not depart from scope of the present invention and can carry out various improvement and/or change.Therefore, the present invention is intended to contain the improvement and the variation of insertion, as long as these improvement and variation drop within the scope of claims and equivalent thereof.
