Steel pipe expansion joint SF-32

roundflangeweld-on

Structure: Steel bellows with hinge restraint and flanges or welding ends. The rotating axis of the hinge restraint is in the middle of the bellows. Movement absorption: Angular movement of the expansion joint is possible. The angular joints regulate a defined angular movement, absorb axial reaction force and relieve the pressure on the pipe‘s fixed points. We differentiate between angular expansion joints with a hinge (bellows angular movement guided on one plane) and angular expansion joints with a cardan hinge restraint (bellows movement guided on two planes). Fixed points: Only light fixed points are required to absorb angular movement force and friction force.
