How Metal Bellows are Made

How Metal Bellows Are Made BELLOWS DESIGN Metal bellows and bellows expansion joints are placed in piping systems to absorb the thermal growth of the pipe. Each time the piping system heats up and cools down the bellows goes through 1 complete cycle.  The manufacturing of a metal bellows starts with the design process. The desired life cycle of the bellows or expansion joint must be determined in order to [...]
