Description

Riser hanger

Technical field

The present invention relates to a support for a pipe or a pipe, and more particularly to a riser hanger. Background technique

The existing riser brackets are as described in GB/T 17 1 16 , 2- 1997 “Pipe Supports and Hangers”, Part 2, P48, see Figure 1. When the medium temperature in the pipe is high, the pipe clamps and bolts need to be chrome-molybdenum alloy steel. , as described in the standards P 54 and P 64, see Figure 2 and Figure 3, the bearing opposite the pipe must be the same or compatible with the pipe material, if the pipe is low PI gold steel or 冋PI ϋζ. steel The support costs a lot of expensive metal materials, when the load is large or the temperature is high or both, or the span of the pipe rack is increased, the structural consumables are more o. In addition, the structure causes the pipe to be partially stressed. Concentration, the pipe stiffness is low when the pipe wall is thin, and the rigidity is lower when the pipe diameter is large. In this case, if the load is large, the instability is easy to occur, which is not conducive to safety. For example, HG/T2 1629 - 1999 "Standards for Pipe Frames", Volume 1 Ρ 14 Figure F 1 (Type III) and Figure F 1 1 , see Figure 4 and Figure 5, the above-mentioned deficiencies of this structure .

At the same time, all of the above structures require non-metallic materials with sufficient dielectric strength to prevent electrochemical corrosion.

Moreover, all the above structures do not consider energy saving, and the production cost is higher when the pipe material is alloy steel or non-ferrous metal.

If a Teflon plate is used as the friction material, the heat transfer distance should be considered. At this time, the size of the lug is larger.

On the other hand, all the above-mentioned structures have a large amount of work on site. In some cases, preheating is required before construction. Non-destructive testing and heat treatment are required after construction, resulting in high engineering cost and long construction period. Summary of the invention

In view of the above-mentioned deficiencies of the prior art, the present invention aims to provide energy saving, save expensive metal materials, reduce construction process, reduce engineering cost, and make the pipe of the hoisting pipe uniform, and prevent electrochemical corrosion. Standpipe bracket and vertical crane with hot pipe and Teflon plate spacing

M The technical solution of the invention is implemented in this way

The energy saving and the festival

The riser hanger of the Berry metal material also includes two perforated booms or lifting plates, and the fastening device on the pipe clamp has a fastening device on the outside or a tight beam on the ends of the rectangular frame. The fixing device, the boom or the hanging plate is coupled with the outer fastening device on the clip or the two-terminal fastening device on the rectangular frame. That is, when the riser hanger is used, the double-row bolt can be arranged at the pipe clamp bolt portion. Use two booms with one end hole to connect with the outer bolts of the pipe clamp. At this time, the part opposite to the bottom of the pipe clamp is preferably two semi-annular plates, and a square or rectangular frame may also be used.

The supporting lug may be a supporting plate or a horizontal luer lug which is opposite to the riser and is connected to the pipe, and is seated on the partition, and the heat insulating layer is seated on the two semi-annular plates or the rectangular frame; The spacer is a two-half-shaped tile forming an annular heat-insulating layer or an N-shaped tile forming an annular heat-insulating layer. The two semi-annular plates or rectangular frame seats are On the pipe rack, the heat insulation layer is a composite heat insulating material, generally a hard material, and for the heat pipeline, the heat insulation layer is made of fly ash or cement sepiolite, perlite, brucite and water glass glue. The material is molded to form a hydrophobic insulation layer. For cold pipelines, usually foamed with a density of polyurethane or dried with natural fiber materials, Waterproof and flame-retardant treatment with unsaturated resin. The gap between the forming partition and the pipe is fixed by the fastening device on the pipe clamp.

The semi-annular plate seat is on the frame, and the inner diameter of the semi-annular plate is larger than the outer diameter of the track, so as to avoid the large load of the bridge, in order to ensure the bearing capacity can be symmetric or asymmetrical under the two half-ring plates under the insulation layer.悍 a rectangular frame or two semi-annular plates between the compartment and the rectangular frame below it, the semi-circular plate and the clip-on half-ring seat on the pipe rack or the rectangular frame and the pipe clamp to the rectangular frame The wooden seat is on the pipe rack; or the two blocks are placed on the wood; or the half ring seat is on the rectangular frame, and the clip is fixed to both the rectangular frame or the rectangular frame and the half ring plate are fixed to each other. The frame or the rectangular frame seat on the frame can be horizontally formed from angle steel, I-beam, channel steel or steel.

As a stand, if the span of the pipe span exceeds the clamp or exceeds the rectangular frame, the length of the clamp or the length of the rectangular frame according to the span of the pipe span can be used to ensure that the two ends of the clamp or the two seats of the rectangular frame fall on the pipe.

Smooth aluminum foil or copper foil or other reflective material can also be sprayed with a reflective layer.

In order to reduce the heat energy loss, it is convenient to construct the elastic soft insulation material between the semi-annular plate and/or the moment frame and the road, such as the temperature-resistant rock wool; in order to ask the energy-saving effect, the heat insulation layer is better stressed. The barrier layer and the portion in contact therewith are partially or completely provided with an elastic soft spacer material.

If a radiation protection layer and an elastic soft spacer material are added at the same time, the radiation protection layer may be applied between the elastic soft heat insulating material and the inner and outer radial faces of the heat insulation layer, or vice versa. At this time, asbestos with aluminum foil on the surface is available.

In order to reduce the friction, the riser hanger and the energy saving and saving precious metal material further comprise a pair of friction pairs and a fixing plate for fixing the lower sliding member, wherein the fixing plate is fixed on the pipe rack, The friction pair includes a lower sliding member and an upper sliding member. The lower sliding member is fixed on the fixing plate. The sliding member is fixed on the riser supporting wood on a supported position of the pipe rack, that is, a semi-annular plate, a rectangular frame or a pipe clamp. Corresponding location.

The upper sliding member is located below the fastening portion of the clamp, such as a bolt portion. To increase the bearing area, a pad is sandwiched between the upper sliding member and the clamp, and the upper sliding member, the backing plate and the pipe clamp are fixed.

The sliding members are all tetrafluoroethylene, or one is tetrafluoroethylene and the other is a stainless steel plate.

Compared with the prior art, the 1π?-effect of the present invention is obvious. The riser bracket or the riser hanger zi disclosed in the present invention saves energy by the special insulation, and the structure is different from the conventional structure. Bug

A large amount of shellfish metal material can be reduced, and thus the cost is low. Obviously, with this structure, the stress condition of the pipeline is greatly improved. In addition, the problem of poor rigidity of the thin-walled tube is overcome, and the problem of instability is also overcome. In addition, the workload of connecting with the pipeline is reduced, thereby reducing many processes. The engineering cost is reduced and the construction period is shortened. At the same time, the insulation of the insulation layer and the elastic cotton effectively avoids electrochemical corrosion. The invention is applicable not only to the support and hanger of the metal pipeline, The same applies to plastic, glass or other non-metallic pipelines and hangers; the invention is not only applicable to pipelines requiring insulation, but also to cold insulation pipelines.
