Teflon lined compensator failure treatment

Teflon lined compensator failure treatment
Teflon lined compensator is better than stainless steel seamless pipe in material and mechanical properties, but the key problem is the removal of internal and external weld residual height, especially the internal weld residual height. In this case, it is necessary to use internal weld seam leveling technology. Teflon lined compensator with internal and external weld residual height is rolled through horizontal roller to remove the residual height, and the cross section becomes horizontal ellipse, and the failure treatment is stuck within the failure treatment to follow; after the vertical roller is rolled, the cross section becomes positive circle, and the failure treatment is separated from the separation, and the frame is pulled back to the proper position by the cylinder when it returns, and then two rolling cycles are carried out. The welded PTFE-lined compensator is conveyed to the deactivation processing machine, and the PTFE-lined compensator is bent by the machine or other deactivation processing device, and when one deactivation processing is completed, it is conveyed to two more to be deactivated for deactivation processing, and so on continuously until all the PTFE-lined compensator deactivation processing is completed, in the form of a single piece of continuous deactivation processing, and then cut, and the length of the single piece of coiled pipe made is 15-133 meters. In the production process of PTFE-lined compensator, the organization and mechanical properties of the deactivation treatment will change greatly due to the high temperature effect of rolling, stretching and welding, which will seriously affect the quality of PTFE-lined compensator. In order to improve the processing efficiency, ensure the surface brightness of tetrafluorine lined compensator up to standard, remove residual stress and obtain tetrafluorine lined compensator, online bright solution treatment is used. When the teflon lined compensator is heated to 1080℃±10℃, the carbide in stainless steel can be fully dissolved and then rapidly cooled to get carbon supersaturated solid solution, thus realizing the online bright solution treatment of teflon lined compensator.
