Universal 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 Universal standard double chamber socket pipes and smooth spigot ends.
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 inserts in the Universal Vi anchoring gasket hook onto the pipe spigot, and thus avoid having to install concrete anchoring blocks.
This anchoring system also avoids the need for a weld bead on the spigot, and so can be used with all smooth spigot ends and in double-chamber sockets.
Description
The Universal standard Vi joint requires the use of Universal standard pipes with double chamber socket. Leak tightness is provided by a Standard joint gasket. The axial force transmission takes place through an anchoring ring with inserts embedded in the elastomer. They hook onto the spigot end when the pipe is pressurized, thus ensuring joint anchoring.
Range
Universal pipes, DN 80 to 600, to be used with UNIVERSAL fittings with similar DN (except DN 350 and 450, use fittings with Standard joint and Standard Vi anchoring solution.)
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 leak tightness of these joints relies on the proven qualities of push-in joints.
- Anchored Without Weld Bead
Unlike some systems, UNIVERSAL Vi provides anchorage without requiring a weld bead on the pipe spigot, simplifying installation and reducing preparation time. - High Pressure Capability
Designed for demanding conditions, it can operate up to 60 bar (depending on diameter), making it suitable for high-pressure water networks. - Secure Anchorage System
Uses a rubber carrier with moulded stainless steel teeth to grip the pipe spigot, preventing joint separation under pressure or ground movement. - Boltless Design
No bolts are required for restraint, reducing installation complexity and maintenance needs. - Flexibility and Deflection
Allows angular deflection (up to 3° for most sizes), accommodating ground settlement and thermal expansion without compromising integrity. - Wide Diameter Range
Available for DN 80–600, covering a broad spectrum of pipeline applications. - Environmental and Cost Advantages
Eliminates the need for concrete thrust blocks, reducing excavation, concrete use, and associated environmental impact.
