Restrained Joint Ductile Iron Pipe

We provide three types of Restrained Joint Ductile Iron Pipe:

1. Tooth Gasket Restrained Joint

2. Outer Anchored Restrained Joint

3. Internal Anchored Restrained Joint

Tooth Gasket Restrained Joint Ductile Iron Pipe

Tooth Gasket Restrained Joint is a little different than the regular T type Joint, it need specially manufactured steel teeth inserted in place of normal gasket, when the spigot is fully inserted, the teeth bite into the spigot and restrict the spigot to come out, and the Tooth Gasket Restrained Joint could be used to connect any T type Ductile Iron Pipe.

The product range is DN80-700, and allowed Max. Angular Deflection is 1.5-2°, and PFA is 10-16Bar.

Outer Anchored Restrained Joint

Outer Anchored Restrained Joint, also namely Bolted Restrained Joint can withstand high pressure, it need the factory to make welding bead on the spigot, and retainer ring, gland, rubber gasket and bolts&nuts are needed to achieve the restraint, it is easy to assembly and disassembly when required.

The product range is DN80-1200, and allowed Max. Angular Deflection is 1-2°, and PFA is 20-30Bar.

Internal Anchored Restrained Joint

Internal Anchored Restrained Joint can withstand very high pressure, it need long socket with two chambers one for sealing and the other for restraining axial movement, the restraining is done by weld bead on the spigot, and it is easy to assemble and disassemble when required.

The product range is DN80-2000, and allowed Max. Angular Deflection is 1-3°, and PFA is 15-40Bar.

Flanged Joint Ductile Iron Pipe

Flanged Joint Ductile Iron Pipe is Ductile Iron Pipe with flange end, the flange comply with EN1092-2 or ISO7055-2.

The Product Range is DN80-2000, Flange Class: PN6, PN10, PN16, PN25, PN40. The puddle flange is available when required.

Jacking Ductile Iron Pipe

Jacking Ductile Iron Pipe is to make a tubular reinforced concrete protective jacket on T type pipe, it is applied to cross road, railway, rivers or buildings when trench excavation is not allowed and the traffic is not affected.

The product range is DN300-DN2000, allowed jacking force is 1200-17000KN.
