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.
To better ensure the safety of your goods, professional, environmentally friendly, convenient and efficient packaging services will be provided.
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.
We are a professional manufacturer of all types of metal flexible metal hose and machinery with more than 35 years of history,such as PTFE hose ,corrugated metal hose, square lock and interlock hose/ conduit, expansion joint, hose making machine, etc...
The hoses are widely used in energy, petroleum, petrochemical, machinery, refrigeration, construction, hydropower, nuclear power,cement, paper, medicine, transportation, mining, metallurgy, urban central heating, shipbuilding, city gas, pipeline construction,central air conditioning, aerospace and other industries. Our products have exported to many countries such as Russia, Ukraine,USA, Australia, New Zealand, Poland , etc..
Protect the corrugation from being damaged by the medium with high corrosion concentration.
The medium conveyed by PTFE bellows is strong acid, strong alkali, high salt and alkali.
