Universal Ve
UNIVERSAL Ve joint
The UNIVERSAL Ve joint is a push-in anchored joint for laying anchoring pipes.
The anchoring is designed to take up axial forces and allows laying without the need for concrete blocks.
It is suitable for double chamber socket pipes with a weld bead on the UNIVERSAL STANDARD Ve spigot end.
Range DN 300 to 1200 (pipes).
Principle
The basic principle of anchoring joints consists in transmitting the axial forces from one pipeline component to the next, thus ensuring that the joint does not come apart.
Anchored joints can be used to distribute, over one or more pipes, the axial force arising at particular points (bends, tapers, tees, blank flanges, etc.), thus avoiding the need to install concrete anchor blocks.
Description
The UNIVERSAL STANDARD Ve joint requires the use of UNIVERSAL STANDARD pipes with a weld bead and double chamber socket.
Leaktightness is provided by a STANDARD joint gasket.
The axial force transmission takes place through a mechanical arrangement, independent from that providing the seal, comprising :
- works applied weld bead on the pipe spigot,
- a one-piece anchoring locking ring with a curved external profile that abuts against the weld bead.
Applications
Anchored joints are of particular interest in congested conditions that preclude the construction of concrete anchor blocks or in poorly cohesive soils.
Performances
The leaktightness of these joints relies on the proven qualities of push-in joints.
