When installing thermal expansion joint, pipe support should be transported to the installation site and installed in place according to the design requirements. Measure the bearing on the pipe rack, elevation, position, and bearing in place after welding. Or is in the pipeline on both sides of the levers of a pipeline slowly pick up two people, then let people will support into the tube, the welding as required.
The expansion of prefabricated double-check before installation, check the model, geometry size and position of weld conformed to the specification requirements, the four square expansion pipe bending Angle should be on a plane, shall not be distorted. Before installing square expansion joint, weld seam of fixed bracket should be welded. Expansion at the ends of the straight pipe and the connection between pipe set aside 1/4 the design of the compensation amount of clearance (plus weld end clearance).With tube stretcher is installed on the two stay welding interface, tighten bolts tube stretcher, pull up force know pipe interface alignment, fixed after welding can weld, weld rear can remove the tube stretcher. This pipe support with thermal expansion pipe installation method is applicable to the heat pipe.
