Hinged Expansion Joints

Product Description

Type: 
single hinged expansion joint
Composed of a bellows, pin shaft, hinge plate and vertical plate and other structural parts, it can only absorb the angular displacement in a plane and can withstand the pressure and thrust of the bellows.
universal hinged expansion joint
Composed of two bellows connected by the middle pipe and structural parts such as pin shafts, hinge plates and vertical plates, the expansion joint can only absorb lateral and angular displacement in one plane and can withstand the pressure and thrust of the bellows.
universal hinged in-line pressure balanced expansion joint
It consists of two working bellows at both ends and a balance bellows in the middle, and structural parts such as pin shafts, hinge plates and vertical plates. It is mainly used to absorb axial displacement and lateral displacement in a plane and balance the pressure and thrust of bellows.
Feature:
1.Absorbs angular movements in only one plane.
2.Eliminates pressure thrust loads.
3.Positive control over the movements.
4.Can support the dead weight of the intermediate piping.
5.Prevents torsion on the bellows elements.
6.Minimum guiding required.
7.Eliminates main anchors.
8.Low forces on piping system and adjacent equipment.
Application:
Air, Steam, Flue Gas Ducts, Power Plants
Chemical Industry, Petrochemical Industry
Gas Turbine System
Primary reformer ducts & burners
Steel Plants
