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.
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.

Examples of Sizes
All data in millimeter.
On each seal, profile thickness, outer diameter, recommended pipe measurement and production period are given. The corresponding data are also on the packaging.
Subject to change for technical reasons
The spigot and socket of the pipe should be checked for damage prior to jointing.
The pipe spigot should be chamfered with an angle of 15°, taking care to remove all burrs.
Both spigot and socket including the sealing ring should be free from dirt and other foreign matter.
Lubricant should be applied evenly to the spigot end of the pipe.
Immediately after lubrication, the spigot should be brought into contact with the socket.
Both spigot and socket should correctly aligned and then slide the spigot into the socket, thus compressing the seal until the joint is fully made.
