Ductile iron pipe with resistant joint (R.J.Pipe)
R.J.Pipe is an advanced design of Push-in flexible restrained Joint that it's locking system prevents from pipe separation while earthquake or subsidence. It is noteworthy that increased safety in water supply networks and significant decrease in water-loss are among the most important advantages of using such pipes.
Using restrained joint leads to the integration of pipeline and distribution of stress and strain that is produced among different components of pipeline. One of the main specification of this kind of joint is ease of assembly and disassembly without bolt and nut.
Standards
:: R.J.Pipe is designed according to ISO 16134 and the joint tested according to ISO10804.
:: Applying external coatings according to ISO 8179 and internal lining according to ISO 4179 and EN 598.
:: Sealing rubber gasket is similar to Tyton joint, following ISO 4633 and EN 681.
:: R.J.Pipe is manufactured according to ISO 2531 or EN 545 standards.
Applications
:: Suitable for earthquake regions and unstable soils, without concrete thrust blocks in the joint place.
:: Suitable for trenchless application systems especially horizontal directional drilling.
Advantages
:: Suitable axial displacement and angular deflection with perfect sealing
:: Easy and fast installation without nut and bolt
:: High resistance against hydraulic forces
Dimensions and weights specifications of R.J.Pipes according to ISO 2531 Standard
