Expansion joint
The PTFE-lined expansion joint refers to lining the interior of the stainless steel bellows expansion joint with tetrachloride to meet the needs of specific working environments. It is a common product type of PTFE expansion joint, please click the link to read our more detailed introduction to PTFE expansion joint. PTFE expansion joints have good elasticity and corrosion resistance, but the pressure-bearing capacity is not high. The strength of PTFE is lower than that of metal materials. For example, the strength of PTFE at room temperature is less than 1/10 of that of stainless steel. So people created PTFE-lined expansion joints to apply to some high-pressure chemical pipelines.
- Higher Pressure Resistance:
Can withstand pressure up to 1.6Mpa - Shock Absorbing:
Flexible Connector with Telescoping Function - High temperature resistance:
the working temperature can reach up to 260 degrees - Corrosion resistant:
acid and alkali resistant and practically insoluble in all solvents - High lubricity:
the smallest friction coefficient among solid materials

The PTFE lined expansion joint inherits the advantages of the PTFE expansion joint and the stainless steel bellows expansion joint at the same time. The PTFE expansion bellows expand and contract with the stainless steel bellows. The stainless steel bellows are used to compensate for the displacement of the pipeline, and at the same time improve the pressure-bearing capacity of the PTFE-lined expansion joint. PTFE expansion bellows are used to isolate the direct contact between the stainless steel bellows and the circulating medium and play the role of anti-corrosion.
There are many choices of corrosion-resistant metal materials, such as 316L, 317L, 904L, 254SMO, 2205, 2507, Hastelloy, Titanium, etc. But most of them are not commonly used and not easy to get. In addition, it is not easy to obtain the material specifications required for forming bellows. The procurement of PTFE raw materials does not have the difficulties mentioned above. As a commonly used anti-corrosion material, PTFE is readily available from many raw material suppliers. And as a non-pressure-bearing component, the PTFE expansion bellows do not need to use different thicknesses according to different design pressures like metal flexible bellows. In the application of large-diameter chemical pipelines, PTFE-lined expansion joints have considerable purchase and cost advantages.
