Earthquake-Resistant DI Pipe, R.J. Pipe

Reliable Investment

R.J.Pipe is an advanced design of Push-in flexible restrained Joint that its locking system prevents from pipe separation during earthquake or subsidence. Notably, increased safety in water supply networks and a significant reduction in water loss are among the most important advantages of using these pipes.

The use of restrained fittings ensures pipeline integrity and helps distribute stress and strain among the various pipeline components. A key feature of this connection type is the ease of assembly and disassembly, eliminating the need for nuts and bolts.

Standards

Ductile iron pipe is designed in accordance with ISO 16134, and the connection is tested according to ISO 10804.
External coatings are applied per ISO 8179, and internal linings follow ISO 4179 and EN 598.
The rubber gasket sealing is similar to the Tyton joint and complies with ISO 4633 and EN 681 standards.

Applications

Suitable for seismic zones and unstable soils, without the need for concrete blocks at the joint.
Ideal for trenchless application systems, especially horizontal directional drilling.

Advantages

Allows for axial displacement and angular deflection with complete sealing
Quick and easy installation without bolts or nuts
High resistance to hydraulic forces
