Wholesale Industrial Stainless Steel Compensator Pricelist, Company

Main Parts And Materials Flange：Q235 End pipe: 304 Corrugated pipe Right:304 Pull rod: Q235 Usage: The working principle of the compensator is mainly to use its own elastic expansion function to compensate the axial, angular, lateral and combined displacement of the pipeline due to thermal deformation, mechanical deformation and various mechanical vibration. The compensation has the functions of pressure resistance, sealing, corrosion resistance, temperature resistance, impact resistance, vibration and noise reduction, reducing pipeline deformation and improving the service life of the pipeline. Application : chemitry industry , oil and gas industry etc.
