In order to improve the circular economy of polymers in terms of sustainability and reduced carbon footprint, the increased use of recyclates has become a topic of major importance. Due to their long design lifetimes, pipe applications represent an excellent opportunity to create added value to non-virgin polymers. In...

Historically, the procedure for butt fusion joining of polyethylene (PE) pipe in the United States has been qualified on the basis of two fundamental tests that are widely recognized within the North American industry. These are the tensile impact (TI) test method found in ASTM F2634 and the bend-back or reverse-bend...

ISO CD 29561 applies to glass fibre reinforced polyethylene pipes and fittings intended to be used for the conveyance of water under pressure for general purposes, as well as for the supply of drinking water. The pipeline may be buried, above ground, or outside buildings. The temperature of the medium to be...

Historically, polyethylene (PE) gas pipe systems in the United States have operated at service conditions for which the likelihood of a failure due to a rapid crack propagation (RCP) event has been nearly non-existent. The exceptional safety record for PE piping systems in this critical application has resulted in a...

Washington Gas has been researching a number of innovative methods for the repair and replacement of older large diameter cast iron mains. We considered direct burial, rolldown, U Lining, PIM, and guided boring. The ideal replacement technique would allow for a fully rated (64 psi or 5 bar) system which would have a...
