Expansion joint installation

The bellows of an expansion joint is manufactured from relatively thin material in order to provide the flexibility needed to absorb the specified movement. The life of the Expansion Can be shortened if the unit is improperly handled and / or installed. This can arise from direct physical damage to the bellows through stresses imposed during installation, or by the factors. Therefore some basic instructions must be followed having safe and proper installation of Expansion joints. There are several other things to consider when choosing whether or not to use a flow liner. Due to lateral movements, the gap between the bellows and the internal sleeve must be designed appropriately in order to prevent contact or binding against the inside diameter of the pipe or fitting. Also, making sure the inside diameter of the internal sleeve does not create back pressure or restrict the flow of media is extremely important, and usually can be avoided by utilizing an oversize bellows. Stainless steel bellows, as a flexible pressure-resistant pipe fittings, are installed in the liquid transportation system to compensate for the mutual displacement of the connecting ends of pipes or machines and equipment, absorb vibration energy, and can play the role of vibration reduction and silencing. They have many characteristics, such as good flexibility, light weight, corrosion resistance, fatigue resistance, high and low temperature resistance.
