We are one of the best manufacturers of Double Bellows with Pipe / Flange. The double expansion joint extends the magnitude of flexibility and is primarily utilized for straight axial motion. When used in combination with other movements, the predominant motion is straight axial. Each bellows acts as a Single Expansion Joint and absorb the movement of the pipe section in which it is installed (independently of the other bellows). Not to be confused with Universal Expansion Joints.
