For Duo-Pro® Double Wall Environment Piping Systems
Alternative method of installing Duo-Pro® double contained piping systems. The coupling slips over the outside diameter of the pipe, allowing the carrier to be welded and pressure tested before sealing the containment.
Ideal Applications Include:
For use with Duo-Pro® double containment piping systems.
3″ (90mm) – 8″ (200mm)
- Ideal for DuoPro staggered welding
- Dis-similar material U
- Independent carrier pressure test
- Conforms to ASME B31.3
- Slips over SDR pipe
- Use existing welding equipment
