Metal expansion joint as a flexible pressure-resistant pipe fittings installed in the liquid conveying system, to compensate for the mutual displacement of the pipeline or machine, equipment joints, absorb vibration energy, can play a role in vibration damping, muffling, etc., with good flexibility, light quality, corrosion resistance, fatigue resistance, high and low temperature resistance. Mainly used in the pipeline is mainly to ensure that the pipeline thermal expansion and contraction when there is an expansion, otherwise it is a hard connection will be a problem. There are other roles such as used in the valve inside, to do the effect of packing seal.
Uses:
1. Expansion joint installed in the water supply and drainage professional pipeline, expansion joints play a thermal expansion and contraction, to protect the role of pipelines.
2. Hydraulic system pipeline installation requires the use of bellows, stainless steel expansion joint corrosion resistance, and to protect the hydraulic system installation.
3. Stainless steel expansion joints are suitable for urban heating pipelines, as well as a variety of pipeline networks for heating. Expansion energy saving to withstand the axial reciprocating movement of the pipeline.
4. Stainless steel expansion joints are used in chemical installation pipeline projects to play the role of hot and cold strain compensation, that is, bellows expansion joints.
5.Stainless steel expansion joints are more often used in the construction of petroleum, chemical, smelting, shipping, power plants, and pipeline installation.
