Causes of Axial Force Reduction and Behavior by Material Type [Technical Explanation]
Explaining the mechanism of "stress relaxation" in gaskets and tightening management!
"A leak occurred from a flange that was supposed to be tightened to the specified torque a few months later." "After performing a re-tightening (hot bolting), the gasket was damaged." Such troubles are not uncommon in the maintenance of plants and piping systems. The main cause cited is the physical phenomenon specific to gaskets known as "stress relaxation." This article will explain the mechanism of stress relaxation, the differences in behavior depending on the material, and appropriate management methods to maintain long-term sealing performance. *For detailed content of the column, you can view it through the related link.
