A Single Expansion Joint is an assembled product of various components like bellows, liners, flanges, tie rods, limit rods, collars.

Single Expansion Joint come equipped with bellow elements and end connections like pipe ends, flanges, weld necks and other optional features such as collars, liners, and covers. The bellows will deflect in any direction or any plane depend on the pipe movement. It is a cost effective design option but requires that the piping be controlled to the direction of the movements of the bellows unit. The pipe expansion joint should not be expected to control the movement of the pipe. If the piping analysis shows that the pipe expansion joint must accept axial compression, then the piping must be guided and constrained so that only that movement will occur.

Single Expansion Joint are least expensive elements and this Expansion Joint will not resist any deflections with any force other than the resistance of the bellows, which is a function of the spring rate times the deflection amount. Single Expansion Joints do not resist the pressure thrust along its axis, which is the product of the pressure times the effective, or cross sectional, area of the bellows.

Kanwal Industrial Corporation has 20+ years of experience in manufacturing Single Expansion Joint for various industries. Bellows Systems has a flexible manufacturing process that takes your design inputs and develops custom bellows and Expansion Joints for your application. We have experience with both ferrous (304 SS, 321 SS, 304L SS, 347 SS, 310 SS, 316 SS, 316L) and non-ferrous (Inconel 600, Inconel 601, Inconel 625, Incoloy 800, Incoloy 800H, Incoloy 825, Carpenter Alloy 20 c53, Hastelloy C-276, Nickel 200, Monel 400) material.
