Product Name: metal Expansion Joint Compensator Stainless Steel Uns N08825 Dn1400 Pn6 Bar Doule Walled Model NO.: DN1400 Application: Chemical Warranty: 6 Months Certification: CE, ISO14001, ISO9001 Customized: Customized Surface Treatment: Silver Plating Material: Stainless Steel Head Code: Round Type: Axial Kind: Corrugated Compensator Connection: Welding Trademark: XQ Transport Package: Wooden Case Specification: DN1400 Origin: China HS Code: 7307 Product Description metal Bellows expansion joint (they are also calledcompensator ) are compensating elements for thermal expansion and relative movement in pipelines, containers and machines. They consist of one or more metal bellows, connectors at both ends, and tie rods that depend on the application. They are differentiated according to the three basic types of movement: axial, angular and lateral expansion joints.metal Bellowsare elastic vessels that can be compressed when pressure is applied to the outside of the vessel, or extended under vacuum. When the pressure or vacuum is released, the bellows will return to its original shape (provided the material has not been stressed past its yield strength).Features of stainless steel expansion joint metal bellows1.Reasonable structure, good elasticity, large range of compensation pipeline and little counter force to the brackets of pipeline.2.Shock absorption and noise decrease, heat and dust insulation, environmental protection and simple structure bracket.3.The displacement can be deflected to prevent damage caused by subsidence of connected brackets and equipment base. It can adapt itself to the centrifugal difference of pipeline installation to provide convenience to installation and maintenance.4.Good resistance to milling, heat, aging and corrosion and long service life.5.Little resistance and little weight. Each performance is better than the compensation device of other materials.6.The temperature range of media is wide:-40-300°c
