metal pipe expansion joint / round / flange / weld-on
for the chemical industry
Max.: 3,400 mm (133.858 in)
Min.: 15 mm (0.591 in)
Steel bellows with hinge restraint and flanges or welding ends. The rotating axis of the hinge restraint is in the middle of the bellows.
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).
Only light fixed points are required to absorb angular movement force and friction force.
