single axial expansion joint

The Single Axial Bellows Expansion Joint is a fundamental component designed to compensate for pipeline expansion or contraction along its centerline. It specifically absorbs axial movement (compression and extension) generated by thermal changes. This simple yet robust design, typically featuring one bellows element with end pipes or flanges, is ideal for straight pipe runs where lateral displacement is minimal. It's widely used in heating networks, steam lines, and general industrial piping to reduce stress on fixed points and equipment. Internal liners (flow sleeves) are often included to protect the bellows from media turbulence and heat.
