Product details
Hinged Expansion Bellow are used to absorb angular movement when it occurs in only one plane. They are also called as Angular Expansion Joints or Hinged Bellows. The construction of the hinged bellows consists of two hinges connected by a common hinge pin. These hinges are designed to absorb the full pressure thrust of the expansion joint. In addition they can be designed to support the dead weight of the piping and equipment, wind loads and similar external loads. Since the pressure thrust is absorbed by the joint hinges, only minimal guiding and intermediate anchors are required at each end of the piping system. The bellows reaction force does not act directly up on the anchors. The anchors should be designed to withstand the friction forces at pipe guides, the angular spring rate and friction moment of the hinges.
