YUXI vent pipe is a plastic pipe made of polyvinyl chloride (PVC) resin without plasticizer. Perforated PVC vent pipe is designed for use in cathodic protection deep anode wells to displace chlorine gas generated by the discharge of DC current from the impressed current anodes. Vent pipe can also be used to add water to a deep well if drying occurs. 

Vent pipe connection methods include socket rubber ring connection, adhesive connection and flange connection.
