Universal Expansion Joint

Universal Expansion Joint suppliers pliant bellows

Universal expansion joint bellows manufactured using stainless steel as an expansion joint material. we design bellows which gives flexible joints. The universal pipe expansion joint consists of two flexible bellows separated by a pipe joint section or spool. The primary purpose of this arrangement is to have a unit which will accept large amounts of lateral deflection. The amount of lateral deflection they can accept is a function of a number of angulations each bellows can absorb and the distance between the bellows. For a given bellows element, the amount of lateral deflection capability can be increased or decreased by simply changing the length of the centre spool.

Since deflections are usually the result of the piping thermal expansion, and universal expansion joints bellows are usually long, our units are designed so that the thermal expansion of the entire unit length is accepted as compression by the two bellows elements. In this way, the overall length of the unit does not change when the piping is heated.

The standard units mentioned in brochure have all been designed to accept the thermal expansion of their length when the high temperature is up to the design temperature shown.
