Three Reasons Why You Should Replace Something That Seems 'Still Usable' and an Explanation of the Dangers of Asbestos

"The gasket removed during maintenance has no damage; can it be reused?" "I want to reuse a packing that has been used once to reduce costs." This is a common concern on site, but to put it simply, reusing gaskets is absolutely not allowed. Major manufacturers also stipulate that "gaskets are disposable (one-way) parts" as a principle. Why is it not permissible to reuse them even if they look clean? In addition to the physical mechanisms that can cause leaks due to reuse, we will also explain the risks of "asbestos" lurking in old equipment. *For detailed content of the column, you can view it through the related link.
