Fluid temperatures and pressures are linearly applied. When that force hits a gasket, it strikes as either positive or negative energy. Vacuum or outward force, steam or cryogenic, the energies rise and fall. Sudden transient forces or cycling effects are a little different, of course, but they still impact system seals as energy. For chemical […]
Gaskets, especially those used on industrial equipment, prevent fluid leaks. The sealing rings are fitted between pipes. They’re also installed between pipes and their fittings. On hoses, in pressure vessels and fuel tanks, on fluid processing equipment, all of these fluid-networked parts require gaskets. To all intents and purposes, the seals are mechanically durable, but […]
Polytetrafluoroethylene is a man-made compound that serves the flange sealing industry very well indeed. PTFE, to use the synthetic material’s abbreviated title, is a thermally stable material. Gaskets made from the fluoropolymer also feature a high level of chemical resistance. Hot and chemically caustic fluids simply slide past the ring gaskets without impacting the substance […]
Elastomers are clearly malleable but not flimsy. They’re compressible, not fragile. You see, just because an elastic seal can deform, that doesn’t mean it’s mechanically weak. It’s the same with chemical resistance, a feature elastomer gasket materials possess in abundance. Stretchy cross-linked molecular chains deform and recover while they repel the effects of corrosive chemical […]
Imagine the following unacceptable case study. An O-Ring is seated within an equally sized groove. What’s wrong with this picture? Well, the rubber won’t compress as it’s installed. Instead, the identically sized O-Ring and circular groove create a snug fit. An effective seal can never form. To create that seal, the cross-sectional width and depth […]
