Veritas Stainless Expansion Bellows

expansion joints are the simplest type of expansion joints. They are compact requiring virtually no additional space beyond the length of bellows and weld ends or flanges for installation. They have further advantage of not imposing a change in the direction of flow. Where small thermal movements are involved and where proper anchoring and guiding is possible single axial bellows provide the most economical solution.

The most common application for a single axial bellows expansion joints is to absorb axial movements of a straight pipe between main anchors. This axial bellows expansion joint should be placed near one anchor and guides should be utilized to ensure proper alignment and movement control as shown in adjacent figure
