Forsheda 601 Power-Lock™ is a sealing system for
plastic pressure pipes. It is an integrated system
where the seal and mandrel act together as a tool
to form the pipe socket during pipe manufacture.
Detailed information is available on request.
F-601 Power-Lock™ seal meets or exceeds current
European standards for pressure, vacuum, deflection
and shear load.
Furthermore the seal design gives low assembly
forces making pipe jointing easier.
Test reports are available from Trelleborg Forsheda
Pipe Seals on request.
Seal Design and Function
Forsheda 601 Power-Lock™ 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 becomes part of the socket forming tool
used to shape it´s own seal groove reducing irregularities and tolerances in the socket.
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.
