STANDARD Vi Joint

Technical solutions

STANDARD Vi joint

The anchored STANDARD Vi 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 all STANDARD sockets and all smooth spigots.

Range : DN 60 to 600

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.
The STANDARD Vi joint gasket with its inserts anchors the socket joint by hooking onto the pipe spigot and so avoids having to install concrete blocks.
This anchoring system also avoids the need for a weld bead on the spigot, and so can be used with smooth spigots and in all STANDARD sockets.

Applications

The anchored STANDARD Vi joint is of particular interest in congested conditions that preclude the construction of concrete anchor blocks or in poorly cohesive soils, as well as laying pipes on a steep slope or in a casing.
The use of the anchored STANDARD Vi joint is not recommended when the joints are subjected to uncontrolled and repeated traction or joint deflection.
The anchored STANDARD Vi joint cannot be used on FGL iron pipes (grey iron).

Performances

The anchored STANDARD Vi joint combines the advantages of flexible joint pipelines with welded joint pipelines.

The anchoring of ductile iron pipelines can be achieved using two technical solutions : insert type anchoring techniques and bead type anchoring techniques.
PAM’s anchoring solutions are designed according to two different levels of performance, plus a supplementary range to cater for some specific situations.
