Manager Liu Xiaolei), Product Overview Insulated joints are a general term for pipeline joints that simultaneously have the sealing performance, strength performance required by buried steel pipelines, and the insulation performance required by electrical corrosion. It consists of assembly, insulating plate, sealing packing, sealing ring and pup joint. Structural features: The insulating joint adopts integral extrusion welding type, and bolt and flange connection types are not allowed. The insulating joint adopts a type in which the insulation and sealing materials are clamped and fixed in the sleeve (assembly). After the insulating joint is assembled, each internal component should be fixed in its corresponding position. The entire insulated joint remains intact under soil pressure, specified pipeline operating pressure, and hydrostatic testing in the factory or on site. The sealing element of the insulating joint is close to the insulating plate inside the joint and has permanent elasticity. Both sides of the sealing element are in direct contact with the exposed metal surface and will not move, ensuring the tightness of the joint. .
