Rubber Ring Joint Jointing
RRJ Rubber Ring Joint Anatomy
RRJ ASSEMBLED CROSS SECTION
- Suitable for both buried and above ground applications
- Size range from DN 300 to DN 1400
- Allowable angular deflection of up to 3°
Advantages of RRJ over welded joints include:
- Faster laying rates
- Less field plant, maintenance and skilled personnel on site.
- No field wrapping or reinstatement of corrosion protection at joints.
- Joints maintain full seal up to pressures that would rupture the body of the pipe, even with angular rotation.
- No need to X-ray pipe joints.
- Local labour and small contractors can be trained to lay pipes easily.
