Insulation joints excellent insulating performance and anticorrosion measures rigid big Overall buriedand and the unique seal

WS-QDQ-JD insulating joints can be eddectively used to provide electrical sectioning and passive protection against corrosion oninlet and outlet pipes of meters,cisterns,tanks,pumping stations,etc...With the optimization of their characteristics,they improve the cathodic protection of gas,water,and petroleum pipeline with considerable savings in operationg and maintenance costs.
