Bellows and lined with corrugated section shall be made of stainless steel metal tube compensation, on the 20th end structure using steel corrugated section shall be rounded negative resistance compensation, should have good anti-stretch and higher fatigue strength, structural design should take full account of the stiffness and strength of the product, there should not be a circumferential weld ripples. rectangular compensation for rounded corners of the structure. corrugated compensation except absorb axial expansion, the subject should be able to absorb a certain angular distortion amount, in addition to meeting all directions outside the compensation amount should still be considered 20% of the amount of deformation margin. Each volume has been set out in the direction of expansion specification table. In order to ensure the quality bellows compensator, assembly personnel should be familiar with compensator works, the role of the parts and quality requirements, assembly quality control methods and so on. Prior to assembly, should compensator with magnetic parts matching sleeve valve compensation, determine the assembly process. If the modification with the process, to ensure the quality of welding, to correct and reasonable control of geometric tolerances, and to keep for inspection, just the quality of assembly will be guaranteed.
