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

Description: Elbow pressure balanced expansion joint is composed of a working bellows or two working bellows connected by an intermediate pipe and a balanced bellows and elbow or tee, head, tie rod, end plate, spherical and tapered washer and other structures. It is mainly used to absorb the combined axial and lateral displacement and can balance the pressure and thrust of the bellows. Usually, the pipeline expansion joint is a constrained general-purpose type that can accept lateral movement. Because there is also axial deflection, pressure balanced elbows are usually required. Feature: Absorbs axial and lateral movements Eliminates main anchors Minimum guiding required Pressure forces remain in balance No volume change Balance-pressure thrust remains constant Application: Elbow pressure balanced expansion joints are used in pipelines with a change of direction. Elbow pressure balanced expansion joints are used with low pressure turbines, with condensers and also with pumps and other equipment, that may be susceptible to pressure loads.

Type: single gimbal expansion joint Composed of a bellows and pin shaft, hinge plate, universal ring and vertical plate and other structural parts, it can absorb the angular displacement in any plane and can bear the pressure and thrust of the bellows. universal gimbal expansion joint Composed of two bellows connected by the middle pipe, cross pin shaft, hinge plate and vertical plate and other structural parts, it can absorb lateral and angular displacement in any plane and can withstand the pressure and thrust of the bellows. universal gimbal in-line pressure balanced expansion joint It consists of two working bellows at both ends, a balance bellows in the middle, and structural parts such as pin shafts, hinge plates, universal rings and vertical plates, which are mainly used to absorb axial displacement and lateral displacement in any plane. And it can balance the pressure and thrust of the bellows. Feature: 1.Absorbs angular movements in all planes, And angular rotations, or any combinations of these. 2.Eliminates pressure thrust loads. 3.Positive control over the movements. 4.Can support the dead weight of the Intermediate Piping. 5.Transmits external loads like wind loading and shear loading. 6.Prevents torsion on the bellows elements. 7.Minimum guiding required. Application: Dilatation points of the buildings Area that seismic movements are occur Fuel tanks Filling Facilities Fire pipelines All pipelines
