Expansion joints are divided into two kinds of flange connection and welding according to the connection way. According to the model is divided into axial type, horizontal type, angle to the type of the more than and 20 types of three varieties. Refinement: universal type, single axial type and external pressure type single axial, unconstrained, spherical, thick wall, single angle type, single gimbal angle type, double articulated horizontal type, universal type, large angle transverse rod horizontal type, horizontal type, small rod buried, buried type, heating network one expansion joint, straight pipe pressure balance, curved pipe pressure balance type, straight bypass pressure balance type, MZP type, MP-A type gas pipeline for gas pipelines, natural gas, disturbance of the gas pipe valve special elastic expansion device, three coal, power plant, steel lined PTFE duct of rectangular fillet, single power plant air cooling system hinge, power plant air cooling system, double hinge duct expansion joint, sleeve expansion joint;
Expansion joints can be divided into a variety of specifications, our company provides DN65, DN80, DN100, DN125, DN150, DN200, DN250, DN300, DN400, DN500, DN600, DN800, DN1000 and DN3000 specifications for products. The expansion joint is a flexible joint which is arranged on the shell of the container or the pipe to compensate for the additional stress caused by the temperature difference and the mechanical vibration.
