PTFE Bellows

PTFE expansion joints are hot formed from PTFE tube made by a tape wrapping process. The tube is processed in such a manner that the PTFE has a low level of crystalline that confers an improved flex life. The seamless PTFE tube has controlled radial thickness and production methods ensure optimum hoop strength which results into an excellent pressure / vacuum with temperature relationship. In most cases, they can match that of PTFE lined steel pipe work and fittings. Applications in process industries for use in both organic and inorganic chemical processing and production, including such demanding applications as agrochemical,  pharmaceuticals, cryogenics, chemicals and food processing. PTFE expansion joints are manufactured in sizes suitable to flanges 1” to 18" with matching flanges of stainless steel, mild steel or as per specifications. In addition to Valve & Line bellows, specially designed bellows are also manufactured as per specifications.
