The field connecting structure for the titanium/steel compound pipeline consists of a pair of titanium/steel compound flanges, sealing gaskets and fastening bolt nuts, wherein a titanium compound layer of each titanium/steel compound flange is arranged on one side of a sealing surface, a steel compound layer of each titanium/steel compound flange is arranged on the other side of the sealing surface, the pair of the titanium/steel compound flanges are respectively connected with the compound pipeline, connecting ends of the compound pipeline expose a titanium pipe layer on the inner layer before assembled and connect the steel compound layer of each titanium/steel compound flange with a steel pipe layer of the compound pipeline, one side of the sealing surface is connected with the titanium pipe layer on the inner layer, and the titanium/steel compound flanges are fixed by the fastening bolt nuts. The field connecting structure for the titanium/steel compound pipeline is capable of bearing a certain working pressure, good in tightness, free of leakage, strong in anti-pulling ability, fast to assemble and disassemble, convenient to use, and capable of effectively avoiding the problems which occur in the process of welding of the titanium/steel compound pipeline.
Description
Technical field
The utility model relates to the installation connection area of pipeline, and the scene that is specially adapted to titanium/reinforced plastics composite pipeline of being comprised of pure titanium and carbon steel material is installed and connected.
Background technique
The fifties in last century, because the high speed development of the industry such as worldwide Aeronautics and Astronautics, electronics, machinery, chemical industry, material has been proposed higher, more, harsher usage requirement, because composite material can overcome the narrow limitation of homogenous material, can satisfy preferably to a certain extent corresponding requirement, therefore composite material just arises at the historic moment, and fast development.
Be used for enough intensity, the titanium materials of burn into that the conveying equipment of ocean environment and seawater corrosion medium must sea water resistance and can adapt to the use under ocean environment fully, still at the position that contacts with steel galvanic corrosion can occur.Titanium/reinforced plastics composite pipeline has following main feature: 1) outside can be born under certain working pressure.2) inside has certain decay resistance.3) because the density of titanium material is lower, thus this multiple tube outside proof strength and corrosion resistance characteristic, can also weight reduction.4) use of alternative single resistant material can reduce the assembling manufacturing cost to a certain extent.5) titanium/composite pipe that has good combination intensity can be avoided directly docking to contact with titanium pipeline and other metals producing galvanic corrosion.Comprehensive above factor, the application prospect of such titanium steel multiple tube is comparatively open.
But because the nature difference of titanium, Steel material, these two kinds of materials cannot effectively be welded.Titanium is high activity metal, at high temperature can violent reaction occur with gases such as oxygen, nitrogen, hydrogen.The melting welding meeting makes its complete embrittlement of weld seam in air.As adopting as the identical butt weld technologies for steel of other single material pipelines connections, will be subject to the serious pollution of outer steel matter at the titanium layer of multiple tube internal layer, cause final can't seam, so this multiple tube pipeline also can't effectively connect.
Summary of the invention
The purpose of this utility model is to avoid direct butt welding between titanium/reinforced plastics composite pipeline to connect that the titanium layer that causes pollutes and can not seam, proposes a kind of joint connection in site structure of simplifying titanium/reinforced plastics composite pipeline.
The technical solution of the utility model is:
Titanium/reinforced plastics composite pipeline joint connection in siteStructure is made of a pair of titanium/steel composite flange, seal washer and clamping bolt nut; Wherein the multiple layer of the titanium of every titanium/steel composite flange is in sealing surface one side, and opposite side is steel multiple layer; A pair of titanium/steel composite flange connects respectively multiple tube, the connecting end of multiple tube all exposes the titanium pipe layer of internal layer before assembling, and the multiple layer of the steel of flange is connected with the steel pipe layer of multiple tube, sealing surface one side is connected with the titanium pipe layer of internal layer, again by clamping bolt nut fastening flange.
The present invention is by multiple tube is existed
Joint connection in siteProcessing is cut in the assembling driving of advancing, so that the outer steel composite bed of multiple tube is excised and the titanium pipe that internal layer is compound comes out in this segment length in a segment length.And with the flange facing side and endoporus carries out chamfering so that follow-up welding.The composite flange of dimension is assemblied on the pipe end, with the GTAW method outside in flange and the multiple tube is welded respectively when being welded to connect.After the cooling to be welded, in the cooperation flange that welding is good respectively, acquire seal washer, and be fixedly connected with bolt and nut subsequently.
The specification of this titanium/steel composite flange can be carried out appropriate design and processing according to the actual specification of titanium/reinforced plastics composite pipeline.Because in reality connected, the titanium layer of multiple tube and the titanium layer of composite flange directly welded, and the steel layer of the steel layer of multiple tube and composite flange welds.The welding of titanium and steel is independently carried out respectively, and assembling is lower hereinto, and welding can be carried out under the protective atmosphere preferably, has avoided because the multiple tube that welding characteristic causes of titanium is difficult to assemble by the mode of welding.
The beneficial effects of the utility model are: the utility model structure can bear certain working pressure, sealing better without leak, that tension is taken off ability is strong, fill, tear open rapidly, easy to use, and can effectively avoid the problem that occurs in the direct welding process of titanium/reinforced plastics composite pipeline.

Fig. 4 is the utility model assembling schematic diagram.
The multiple layer 1 of the titanium of flange, the multiple layer 2 of steel, titanium pipe layer 3, steel pipe layer 4, soldering point 5, bolt 6.
Embodiment
Concrete execution of the present utility model is as follows:
1 makes titanium/steel composite flange.Determine the relative dimensions of flange according to the size of pipeline.And the A side in titanium/steel composite flange carried out interior chamfering, chamfer dimesion is decided according to the titanium layer thickness of titanium/reinforced plastics composite pipeline.Referring to Fig. 1;
The sides to be connected of 2 pairs of multiple tubes that prepare to connect are carried out the turning of certain-length, the consistency of thickness of turning length and stand-by composite flange, and the diameter of tubing should be advisable guaranteeing to closely cooperate with the flange endoporus preferably after the turning.Referring to Fig. 2;
3 install, and the pipeline that turning is good is connected with flange.Require the flange back side to contact with Steel pipe end surface well in the connection procedure, without larger space.Such as Fig. 3;
4 adopt the GTAW welding method that flange and titanium/reinforced plastics composite pipeline are welded.The welding of steel layer and the composite flange steel interlayer of multiple tube is carried out first in requirement.After this carry out the welding of titanium layer part, i.e. the welding of flange chamfering place and composite pipe internal layer.And to guarantee that weld reinforcement is no more than the height of sealing surface when requiring the welding of internal layer titanium layer, and then avoid too high because of weld seam, cause the situation of poor sealing to occur.
5 put into suitable sealing gasket, carry out sealing and reinforcing;
6 put into clamping bolt at the flange upper bolt hole, and fastening nut, thereby finish the connection of on-the-spot titanium/reinforced plastics composite pipeline.Such as Fig. 4.
