(44) Molded PTFE Expansion Joints API‘s molded expansion joints and flexible couplings were specially developed to withstand the higher pressures and temperatures in today’s piping systems. Each molded bellows contain the properties required for fatigue-proof operation.
High density for low permeability.
High tensile strength for greater working pressures.
Low crystallinity for longer flex life.
Material orientation for reduced stress concentrations and / or premature fatigue failure.
API PTFE expansion joints are available in 2, 3, 4 & 5 convolutions.
Note: Nom-Length is approximate and may vary. Each PTFE expansion joint comes with metal flanges and tapped bolt holes that ...
