Reasons for external leakage in ball valves using ethylene oxide as the medium
Thread Content
Ethylene oxide is highly flammable, explosive, and toxic, making it unsuitable for long-distance transportation. Today at Ningbo Saiding Engineering Company, the ball valves made of ethylene oxide, which were under their general contracting in Jilin, experienced leaks during the commissioning phase. Preliminary analysis shows that the gasket used in the valve is fluororubber, rather than polytetrafluoroethylene as specified in the design by the valve manufacturer. The fluororubber has rotted. Please have experts analyze together: with ethylene oxide as the medium, what material should be used for the seals?
The valve manufacturer did not use the polytetrafluoroethylene required per the design. The fluororubber has rotted. ------------------------------ For items with special specifications and design requirements like this, special acceptance procedures are required
