Background technology
With being growing more intense for composite steel tube market competition, producer starts to open up composite steel tube in non-oilfield market in industry Application.In composite steel tube connection procedure, the pipe end processing mode of composite steel tube directly affects the joint quality of composite steel tube, The final service life for influencing composite steel tube.Composite steel tube manufacture industry is handled for composite steel tube port at present, is generally used Two methods of pipe end soldering and sealing and built-up welding, both approaches require that comparison is high to welding procedure and welder's operation technique, and scene is applied Work difficulty is larger.
Utility model content
The purpose of this utility model is to provide for the socket joint welding system of lined composite steel tube, which can be multiple Close pipe end it is not damaged it is expanding in the case of, coordinate novel pipeline interconnection technique, overcome pipe end soldering and sealing and technique for overlaying technique, The defects of operation technique is more demanding, and site operation difficulty is larger.
To achieve the above object, the technical solution of the utility model is:
A kind of lined composite steel tube socket joint welding system, it includes fixed steel pipe clamping equipment, the steel pipe clamping of movement is set Standby, pedestal, driving mechanism and slide, the slide are arranged on the pedestal, and the fixed steel pipe clamping equipment fixation is set It puts in pedestal one end, the steel pipe clamping equipment of the movement is arranged on slide, the driving mechanism and the fixed steel pipe Chucking device connects.
The driving mechanism includes drive cylinder and pull rod, and pull rod one end is fixed at mobile steel pipe clamping equipment On, the pull rod other end is connected by fixed steel pipe clamping equipment with drive cylinder, and the drive cylinder is connected by the pull rod Connect the steel pipe clamping equipment for the movement that can be moved on slide.
The drive cylinder has 2, and the pull rod has 2.
The utility model has the advantage of:Conventional composite steel-pipe welding mode is changed, avoids the various of welding point Defect, connection mode is simple, and socket joint intensity is high, internal lining pipe without corrugation, craftsmanship is required it is relatively low, it is applied widely.

Specific embodiment
As shown in Figure 1, 2, the utility model discloses a kind of lined composite steel tube socket joint welding system, it includes fixed steel Tube grip device A 1, mobile steel pipe clamping device A 2, pedestal A3, driving mechanism and slide A4, the slide A4 are arranged on institute It states on pedestal A3, the fixed steel pipe clamping device A 1 is fixed at pedestal A3 one end, and the steel pipe clamping of the movement is set Standby A2 is arranged on slide A4, and the driving mechanism is connected with the fixed steel pipe clamping device A 1.
The driving mechanism includes drive cylinder A5 and pull rod A6, and pull rod A6 one end is fixed at mobile steel pipe folder On holding equipment A2, the pull rod A6 other ends are connected by fixed steel pipe clamping device A 1 with drive cylinder A5, the drive cylinder The steel pipe clamping device A 2 for the movement that A5 can be moved by the pull rod A6 connections on slide A4.
As shown in Fig. 2, wherein drive cylinder A5 has 2, the pull rod A6 has 2.
The method for connecing lined composite steel tube using lined composite steel tube socket joint welding system socket joint disclosed in the utility model, Step is as follows:
First, a lined composite steel tube one end is expanding, it is processed into and accepts steel pipe A7, expand as shown in figure 3, accepting steel pipe A7 The pipe end internal diameter of path portion divides internal diameter of tube body transition position to form intermediate incline A71 with non-wide diameter portion;
Second, by the necking of another lined composite steel tube one end, grafting steel pipe A8 is processed into, as shown in figure 4, grafting steel pipe contracts Mouth end outer wall forms taper angles A 81, as shown in figure 5, taper angles A 81 is consistent with the undertaking steel pipe A7 pipe end intermediate incline A71 angles;
Preferably, the taper angles A 81 of grafting steel pipe A8 pipe ends is formed using lathe process;
3rd, it is applied in the undertaking expanding end inner walls of steel pipe A7 and 81 outer wall of grafting steel pipe A8 necking ends taper angles A Smear dope;
The dope used in the present embodiment is random carboxylic butyl- epoxy corrosion resistant fluid sealant;
4th, using above-mentioned lined composite steel tube socket joint welding system, by the undertaking steel pipe A7 flared ends and the grafting Steel pipe A8 necking ends dock, and apply pressure, two lined composite steel tubes is made closely to connect.
Specifically as shown in Figure 1, being clamped in steel pipe A7 is accepted in fixed steel pipe clamping device A 1, by grafting steel pipe A8 It is clamped in mobile steel pipe clamping device A 2, starts driving mechanism, drive cylinder A5 pulls pull rod A6 to drive mobile clamping Steel pipe equipment A2 is close to fixed clamping steel pipe equipment A1 on slide A4, so that it is tight to accept steel pipe A7 and grafting steel pipe A8 Close socket joint connection.
It is only the preferred embodiment of the utility model in summary, is not used for limiting the implementation model of the utility model It encloses.The equivalent changes and modifications that i.e. all contents according to present utility model application the scope of the claims are made, all should be the utility model Technology scope.
