Flange gasket is the core component of pipeline and equipment flange sealing system. OnceFailure of flange gasketIt is prone to medium leakage, material leakage, pressure relief and other faults, which can seriously affect the safe and stable operation of the entire equipment. In actual working conditions,Reason for damage to flange gasketVery complex, commonly including improper installation and assembly, uneven bolt pre tightening force, flange sealing surface deviation, high and low temperature alternation, system pressure fluctuations, water hammer impact, medium corrosion aging, incorrect gasket selection, product quality defects, and many other situations. different materialsMetal wrapped gasket, rubber gasket, PTFE gasket, graphite gasketThe failure manifestations of damage, cracking, swelling, and creep relaxation are also different. To completely solve the problem of flange leakage, it is necessary to accurately determine the type of gasket failure and avoid common issues such as installation, working conditions, and material compatibility from the root.
