The STANDARD joint is a push-in joint. The seal is assured during assembly by radial compression of an elastomer joint gasket. Their main features are:
– ease and rapidity of installation,
– high pressure resistance,
– possibility of gap and angular deflection.
Range: DN 1200 to 2 000
The seal is provided by radial compression of the joint gasket, simply achieved during assembly by introduction of a spigot into the socket.
The socket chamber contains:
– a deep housing with an annular anchor groove for the gasket,
– an annular cavity allowing pipe angular and longitudinal movements.
The gasket has:
– an anchoring heel,
– a bulky body with a centring chamfer.
Pipes: DN 1200 to 2,000.
Fittings: DN 1200 to 2,000.
Laying below the water table.
These joints can also be used above ground because of their ability to accommodate expansion and contraction movements.
The STANDARD joint is designed so that the contact pressure between the gasket and metal increases as the water pressure increases. A perfect seal is thus guaranteed.
When tested to destruction the pipe bursts before there is any joint leakage.
A feature of the STANDARD joint is its resistance to external pressure : resistant to 3 bars (30 metres head). Please consult us for higher pressures.

Angular deflection and gap
The degree of angular deflection afforded by the STANDARD joint allows great flexibility in design and laying, enabling elimination of some bends.
The STANDARD joint accepts gap, enabling it to accommodate small expansion and contraction movements.
The gap must be regarded as a safeguard and not be used to accommodate repeated backward and forward movements.
The degree of angular deflection and withdrawal afforded by the STANDARD joint gives it an excellent performance in cases of ground movement or undermining by soil scouring.
