1:details: 

Rectangular duct fabric expansion joint is also called non-metallic compensator, non-metallic expansion joint. Is a high performance non-metallic material, advanced structure, reliable performance, it has a universal power compensation and absorb thermal expansion characteristics, with a high resistance, low temperature, pressure, corrosion resistance, enable the role of the left at a fixed point in force is almost zero (in the design calculations can be ignored), installation of large degrees of freedom, axial radial allow greater deviation of up to 10% of pipe diameter, -20%, can muffler isolation, and may from time to by the pipe dimensions and shape of the restrictions, flexible fabric expansion joints can greatly optimize the quality, the ideal metal rigid expansion joint replacement products, various kinds of imported fabric compensator is a good alternative.

The product is now widely used in steel mills, aluminum plants, cement plants, power plants and other industrial enterprises in the hot and cold air pipes, fans import, export and industrial furnaces heat pipes, the use of plant products Huitong plumbing works well, has won user praise.

2:we can supply:

1.Flange - Steel to SABS 1431 Grade 300WA 

2.DN20mm - DN3000mm.

3.The bellows consists of two symmet

3:Advantages:

1) Expansion joint are low cost vibration and deflection absorption components in fluid conveyance pipelines.

2) The bellows consists of two symmetrical connecting ends, either threaded unions for smaller nominal bores or flanged ends for larger nominal bore pipelines.

3) The body of the bellows is essentially a robust rubber cylinder that is capable of absorbing vibration and movement in pipeline components.

4) Bellows are often installed in-line with water pumps as the absorber of the operating vibration of the pump and movements due to pump start up, shut down.

5) Bellows are also able to absorb axial displacement due to pipeline expansion and contraction, and lateral displacement and pipeline angularity.
