PETROSYSTEM SrlGRIP LOCK PIPE PLUGS NS General function and application: PE's grip-lock pipe plugs are used as a pipe end seal to prevent the outflow of line product or the inflow of debris. They can also be used for emergency isolation while a repair or inspection is carried out. Manufacture The bodies are made from carbon steel and the seals from PE's proprietary low hysterisis elastomer formulation. The tools are fully tested and certified prior to mobilisation. Application and operation As the grip lock plug is tightened inside the pipe the seal expands and the vice rings progressively grip against the pipe wall. The seal is self-energising in that as internal pressure is applied the seal is further compressed. A section of the seal package is abrasive coated to improve grip. Plugs feature a by-pass port to allow pressurisation, filling, venting or pigging. Typically sizes up to 6 " are mechanically tightened and 8 " and above are hydraulically tightened. Configurations, sizes and pressure ratings Plugs are available for sale or rental up to 16 " diameter. The safe working pressure of the grip-lock pipe plugs is up to 207 bar. For equipment above 16 ", specified pressures and specialised applications, please contact our Sales Team or Technical Office.
