STANDARD Ve Joint

Technical solutions

STANDARD Ve joint

The STANDARD Ve joint is a push-in anchored joint.
The anchoring mechanism takes up the axial forces and allows concrete anchor blocks to be dispensed with.
Range : DN 80 to 1200.

Principle

The principle of joint anchoring consists in transmitting the axial forces from one pipeline component to the following one, thus ensuring that the joint does not come apart.
Anchored joints allow the axial thrusts arising at particular points (bends, tapers, tees, blank flanges) to be distributed over one or more pipes, thus avoiding installation of concrete anchor blocks.

Description

The seal is provided by a STANDARD gasket.
The axial force transmission is through a mechanical arrangement, independent of that providing the seal, comprising :
- works applied weld bead on the pipe spigot,
- a one-piece or segmented anchoring locking ring (depending on the diameter), with a curved external profile, which abuts against the weld bead,
- a special gland (different from the EXPRESS gland), which blocks the locking ring
- iron bolts (possibly special steel with bearing plates in iron for high pressure and large diameter applications).

Range

The anchored STANDARD Ve joint must be used only on STANDARD pipes class K9 and STANDARD fittings DN 80 to 1200.

Applications

NATURAL pipes DN 60 to 300 (class 40) cannot be used for this anchoring solution.
To use it on C30 pipes from NATURAL range DN 350 to 600, please consult us.

The use of anchored joints is of particular interest where congested conditions preclude concrete anchor block construction or in poorly cohesive soils.

Performance

Anchored joints combine the advantages of flexible joint pipes and welded joint pipes.
