Product Description

 

SS316 stainless steel flexible bellows expansion joint introduction:

Steel bellows expansion joint are also named for the expansion joints, bellow expansion joint, bellows compensator, is a kind of flexible, thin wall, a transverse corrugated device with telescopic functions, it is made up of metal corrugated pipe and components. Bellows compensator’s working principle is mainly using their elastic scaling, to compensate the axial, angular, lateral and combined compensation due to pipes’ thermal deformation, mechanical deformation and all kinds of mechanical vibration, the role of compensation has pressure, sealing, corrosion resistance, temperature resistance, impact resistance, anti-vibration noise reduction function, it could reduce the pipe deformation and prolong the service life of pipelines.

 

multi-layer hydraulic-formed bellows specially designed to eliminate movements in piping where high requirements are  made of working life and safety. Where the standard bellows have a working life of 1000 cycles, the HP bellows are designed for at least 2000 cycles. With the hydraulic movement of the bellows large movement absorptions and small
fitting lengths become possible. The multi-layer bellows construction guarantees a high rate of flexibility by its high waveform and low spring constant. Liwei bellows are particularly suitable for the absorption of large movements, vibrations and high pressures.

 

SS316 stainless steel flexible bellows expansion joint working principles:

1) Compensating and absorbing pipeline axial, lateral and angular to the thermal deformation.

2) Absorbing equipment vibration, reducing equipment vibration effects on pipelines.

3) Absorbing earthquake, subsidence deformation of pipeline.

 

SS316 stainless steel flexible bellows expansion joint classification:

1)  According to whether can absorb piping within the medium pressure generated by the thrust (blind plate force), steel bellows expansion joint can be divided into no constraint bellows expansion joint and constraint bellows expansion joint;

 

2) According to the displacement type of bellows expansion joint, it can be divided into axial type, horizontal type bellows expansion joint, and angular type bellows expansion joint and pressure balance type bellows expansion joint.

 

SS316 stainless steel flexible bellows expansion joint application:

 

1) Large deformation and the deformation but spatial location limited pipeline.

2) Large deformation and displacement but low pressured large diameter pipes.

3) Be restricted to take over the load equipment.

4) Asked to absorb or high frequency mechanical vibration of pipeline.

5) To absorb seismic or foundation settlement of the pipeline.

6) Shock absorption pipeline pump exports.

 

SS316 stainless steel flexible bellows expansion joint installation:

 

1. According to the need to connect both ends of the joint and dislocations, choose accurate product and the right length;

 

2. when installation, back off on both ends of the connector first, and the joint respectively installed on the tube for the fan (back) on pipe interface, should be closed tightly

 

3. The corrugated pipe bending, looping nut should be placed at both ends of the corrugated pipe, so as to avoid corrugated pipe bending die the nut on the card. Pay attention to in the process of installation, don't hit crowded with hard objects, do not damage the sealing surface.
