STANDARD V+i Joint

The anchored STANDARD V+i 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: DN350 to 600.

Principle

The basic principle of anchoring joints consists of transmitting the axial forces from one pipeline component to the next, thus ensuring that the joint does not come apart.
The anchored STANDARD V+i joint gasket with its inserts anchor the socket joint by hooking onto the pipe spigot and so avoid having to install concrete blocks.
This anchoring also avoids the need for a weld bead on the spigot, and so can be used with smooth spigots and in all STANDARD sockets.

Description

Leaktightness is provided by a STANDARD joint gasket.
The axial force is transmitted by a mechanical device that is independent from the actual leaktightness, which includes:

• an anchoring gasket with inserts embedded in the elastomer. They hook onto the spigot end when the pipe is pressurized, and so ensure joint anchoring;
• a special gland (different from that used for the EXPRESS joint), which blocks the anchoring gasket in place;
• iron bolts.

Range

STANDARD fittings DN 350 to 600 to be used with UNIVERSAL Vi pipes with similar DN, especially for DN350 and 450.

Applications

Anchored joints are of particular interest in congested conditions that preclude the construction of concrete anchor blocks, or in poorly cohesive soils.

The anchored STANDARD V+i joint cannot be used on FGL iron pipes (grey iron).
STANDARD joint V+i cannot be used on c30 pipes from NATURAL range DN350 to 600.

Performance

The leaktightness of these joints relies on the recognized qualities of push-in joints.
