Secondary-contained large diameter

Secondary-contained system offers a pipe-in-pipe solution for larger diameters within industrial fuelling applications. The primary polyethylene pipe has an internal permeation barrier specifically designed to offer maximum environmental protection, and is held centrally by spacers to a secondary pipe offering environmental protection in the event of a leak. Secondary-contained is used for above and below ground applications in bulk transport refuelling applications such as rail and marine where high volumes of fuel are transported from tank to dispenser.
