Useful Info:

Durapipe PLX Pipe-in-Pipe pipework is a dual-contained system, manufactured from black polyethylene with a protective co-extrusion barrier bore layer used in marinas and rail yards where large volumes of fuel are required or where transportation of fuel contaminated water is necessary. Other uses for this pipe system include above and below ground applications.

Due to the secondary containment, the user has the ability to monitor interstitial space for leak detection for added security.

Available within this system are 6-metre pipe lengths and a wide range of electrofusion fittings, pressure rated to 10 bar at an operating temperature of 20°C.
