For insulating joint standards, the insulating joint plant, insulating joints Price insulating connector is buried steel pipeline requires sealing performance, strength properties and electrochemical corrosion to the requirements of insulation properties of the pipe joints collectively at the same time. It contains the assembly of the insulating plate, packing, sealing rings, short tube. It is the alternative insulating flange. Product use insulating joints are widely used in gas transmission and distribution systems and gas regulator station, the surge tank. Can effectively between gas transmission and distribution pipelines and regulator stations, surge tank are insulated from each other, protect against galvanic corrosion, to ensure the safety of the medium transport, to extend the life of the pipeline, with a maintenance-free, adaptable, life long is the indispensable parts in the pipeline cathodic protection chaotic system. Features insulating joint overall extrusion welded, not bolted flange connection type. Insulating joints is a reference to the German standard technology to produce products pass four parts to complete both ends of the steel structure insulation, the insulating layer is sandwiched between the insulating joints of the upper and lower catheter, catheter on addition insulation between sets, jackets and under between the catheter together as one, and eventually formed between the upper and lower conduit insulated from each other by a certain process, and external seal.
