Gaskets are used as sealing elements for equipment such as pumps, pipe valves, pressure tanks, reaction tower kettles, etc., and are placed between two flanges to strengthen the seal and prevent leakage at the joint. Qishine mainly provides metal gaskets and insulating gaskets. Metal gaskets include spiral wound gaskets and metal ring gaskets, which are mainly used in petroleum, petrochemical industries and food industries. Flange isolation kits are mainly used in cathodic protection systems in pipelines.
