Mechanisms of "Thermal Degradation" and "Crazing"【Technical Explanation】
An explanation of the risks of "over-tightening" that should never be done, based on technical materials from Nichias!
In the field of plant maintenance, issues with steam line leaks are never-ending. Many of these problems stem from a "selection mistake" where "joint sheets for general piping (water and oil)" were carelessly used in steam piping. "I thought it would be fine because the catalog said it was heat-resistant up to 150°C." This complacency can be fatal. There are clear physical reasons why only "steam-specific" materials should be used for steam piping. This article will explain the mechanism of "thermal degradation (hardening)" that occurs when the wrong gasket is used, as well as the risks of "re-tightening," which should absolutely be avoided, based on technical materials from Nichias. *For detailed content of the column, please refer to the related links.
