Metal bellows expansion joints (also called compensators) are compensating elements for thermal expansion and relative movement in pipelines, containers and machines. They consist of one or more metal bellows, connectors at both ends, and tie rods that de
PTFE Expansion Joints also offer low spring rates resulting in low reaction forces on adjacent piping, nozzles, structures, and equipment. Expansion Joints are well suited for use on non-metallic piping systems such as FRP, glass-lined, PTFE-lined, Kynar, and other corrosion-resistant piping materials.
This expansion joint combines the properties of metal and PTFE into the most advanced expansion joint available for highly corrosive piping systems. Normal design temperatures are from -300F to +400F, and they will retain their pressure carrying capacity up to 1,200F in an upset condition, sufficient time for system shut-down and replacement.
