Product description:

1.Expansion joint is also called bellows or compensators, which are designed for axial, lateral and angular movements, misalignment and/or vibration in piping systems.

2.Expansion joints come with three convolutions as a standard. More than three convolutions can be customized and the more convolutions, the more movement an expansion joint will provide. Various reinforcements of rings and outer shells are available for high pressures, temperatures or vacuum performance. Tie rods and hinges are designed to limit maximum and minimum movements or preventing movement altogether in certain planes.

3.If there is no specific requirement for flange, it will be as per ANSI B16.5 and HG/T 20592 PN1.0MPa standard.

4.Lining material: PTFE, PFA etc.

5.Nominal diameter: DN25~DN3000
When the size of expansion joint is bigger than DN300, the type with stainless steel housing for vacuum resistant is recommend.

 

 

PTFE compensator, can be called as bellow, also known as expansion joint, it can be used to eliminate channels such as container and equipment because of climate change caused by stretching or other reasons leading to the thermal expansion or displacement. PTFE compensator is one type of relief vibration. It can pump installed in the import and export of high-freqency or other machinery at both sides to reduce or eliminate the vibration and improve the life of pipes and sealing performance. Resolve the problem that the metal compensator can not solve, reduce the business costs and improve the production efficiency. In addition, PTFE compensator can be used to absorb the actual design and installation deviation. Working with reliable, compact and strong compensation to all kinds of medium and long service life of corrosion and other advantages.
