First, the overview of Insulated rail joint:Insulated rail joint is gas and oil pipeline transmission and distribution system pipelines indispensable accessories, mainly used in gas transmission and distribution system and gas regulator stations, its role is to gas transmission and distribution pipeline between the paragraphs, transmission and distribution pipelines and gas regulator station mutual insulation isolation, protection from electrochemical corrosion and prolong life, but also the use of direct buried.

 

       Second, the product structure and working principle:Monolithic insulating joints composed of parts from the following: up, down, sleeves, insulating parts, seals, insulation coating.In the insulating joint upper and lower pieces of pipe butt end, there are the pieces of insulation.And seals, to form a double seal structure insulation.Sleeve with groove or welded directly on the catheter in two forms, will insulating parts and the upper and lower tube wrapped in a firmly sealed inside.Surface to form a "closed container", which not only ensures good insulating effect, and also greatly improve the bearing capacity of the insulation.
