Heat treatment has become a key step in the manufacturing of sealing springs, making significant contributions to improving their efficiency, durability, and service life. This treatment involves strategic applications of heat and cooling methods, intentionally altering the physical and chemical properties of the material. It is mainly applied in the metallurgical field and also greatly beneficial...

In liquefied natural gas (LNG) applications, valves can regularly encounter temperatures below -320 F (-196 C) and pressures above 750 pounds per square inch (psi). The equipment faces constant thermal cycling, conventional seals risk failure, leading to dangerous leaks and operational shutdowns. Lip seals excel in these extremes by maintaining elasticity and sealing integrity even under cryogenic...

A ball valve may look simple from the outside, but sealing becomes much more demanding when the valve operates under high pressure. The seal must maintain contact with the sealing surface while dealing with pressure changes, temperature variation, media compatibility, and repeated valve operation.   So, how does a high-pressure lip seal work in a ball valve, and what makes it different from a...
