PTFE Expansion Joints

PTFE Expansion Joints
Our PTFE expansion joints are supplied and successfully used by a wide range of worldwide process industry customers. Their uses cover organic and inorganic chemical processing and production, including such demanding applications as agrochemical and pharmaceutical chemical production, acid processing and food manufacture.

Capabilities
25mm - 800mm nominal bore
Available in 2-10 convolutions
PTFE expansion joints are hot formed from PTFE tube made by a tape wrapping process.
The PTFE tubes have a low level of crystallinity which confers an improved flex life.
The seamless PTFE tube has a controlled wall thickness ensuring optimum hoop strength and excellent pressure/vacuum versus temperature relationship in the finished bellows.
End fittings have ductile cast iron flanges drilled and tapped to ANSI and DIN standards.
Other standards and materials can be accommodated.
Expansion joints are also fitted with stainless steel support rings and limit bolts with lock nuts.
