The Forsheda 601 Power-Lock™ integrated system uses the mandrel together with the seal as a tool to form the pipe socket during the manufacturing process. The seal becomes part of the socket forming tool used to shape its own seal groove reducing irregularities and tolerances in the socket.
Seal design & function
The Power-LockTM is a composite seal consisting of:
A flexible rubber element to seal effectively against spigot and socket
A polypropylene reinforcement element, bonded to the rubber, which holds the seal firmly in place
The seal is equally effective under both positive and negative pipe pressure (vacuum). Under positive pressure the higher the pressure the greater the sealing force.
Under vacuum the seal maintains a positive sealing force against spigot and socket to prevent sand or soil entering the joint.
F-601 Power-Lock™ seal meets or exceeds current European and ISO standards for pressure, vacuum, deflection and shear load.
The seal design gives low assembly forces making pipe jointing easier. Improved productivity and lower scrap during belling process for the pipe producer when compare to traditional integrated seals.
Power-LockTM tolerates ovality effects caused by transportation or storage of the pipe better than other integrated seals. Eliminates the risk of corrosion by removing metal inserts.
