Product Description

Reliable Quality Flexible Metal Bellows/PTFE Lined/Rubber Expansion Joints Flange Connection Compensators

Product Description

A: PTFE lined expansion joints combine the properties of metal and PTFE into the most advanced expansion joint available for highly corrosive piping systems.
 

 B: PTFE expansion joints are flexible connectors that allow movement in a rigid piping system.
Our PTFE expansion joints are made from the synthetic material Polytetrafluoroethylene, the non reactive material is widely used in pipelines within the chemical manufacturing industry, acting as a protective agent against corrosive substances.
 

C:Metallic expansion joints are for the chemical industry, metallurgy, electricity, shipbuilding, construction and other industries.

D: Rubber expansion joints can be selected according to the different pipeline transportation media.

1) Natural rubber joint products are suitable for transporting water and sewage media.

2) EPDM rubber joints are suitable for transporting weakly acidic and alkaline media and media with a temperature within the range of 120°C.

Solid-molded PTFE expansion joints are corrosion-resistant and made to withstand the high pressure and temperature in a compact, space-saving design. Standard sizes from 1" to 12" with two, three, or five convolutions; available in sizes up to 48". PTFE expansion joints can operate with temperatures from -300 F to 400 F from a full vacuum to 160 PSI depending on the type and number of convolutions.
