Metal bellow expansion joint
Metal bellow expansion joint is the most common and popular, it is mainly used in pipe connection, aborb the extension and compression of pipe, according to different working situation, usually we recommend different structure, but for most common, we recommend general stainless steel metal bellow expansion joint, it is consist of two flanges, tie rods and bellows, according to actual working situation, you can choose to add inner sleeve or change structure, and we can offer you drawing for confirmation, about the material of bellow, we can do SS304, SS316, SS321 and SS310s etc, for working pressure, we can do PN16, PN25, PN32, PN64, PN100 etc. for working temperature,we can do 1000 celsius degree etc. And we can do OEM and ODM production for you.
Metal expansion joint without tie rod
Expansion amount is 20-120mm, no leakage, no padding, good scalability, safe and reliable, can save maintenance workload, the compensator has novel and reasonable structure, without wearing parts, small volume, light weight, easy to install and for transportation, is the ideal product for installation of pipes.
The compensator&metal expansion joints are used in a wide variety of piping application to compensate for thermal expansion or contraction and to absorb equipment vibration or pipe motions.
- We manufacture single, two-ply and multiply testable bellows in different sizes using precision forming technology.
- They are used as an retractable elastic compensation element, has the advantages of the reliable working, good performance, compact structure.
- The compensator&Metal expansion joints absorb movement in piping caused by theraml changes.
- Durability and excellent chemical resistance.
- Widely used to absorb termal expansion in pipe systems carring water, steam, oil and gases.
