Driscopipe - Model 8100 - Polyethylene Pipe
From Gas Distribution
This high density polyethylene (HDPE) PE4710/PE100 (PE3408) solution is black with a solid yellow exterior shell. HDPE gas pipe is the preferred option for those applications where pressures up to 125 psi may be encountered, or where higher operating temperatures may be experienced. The yellow shell provides a unique color differentiation of the fusion bead as well as a visual indication of OD scratches or gouges, while keeping the OD surface cooler during exposure to direct sunlight.
