GENERAL

Polyethylene (PE) is a thermoplastic material produced from the polymerization of ethylene. PE plastic pipe is manufactured by extrusion in sizes ranging from ½" to 63". PE is available in rolled coils of various lengths or in straight lengths up to 40 feet. Generally small diameters are coiled and large diameters (>6" OD) are in straight lengths. PE pipe is available in many varieties of wall thicknesses, based on three distinct dimensioning systems:

• Pipe Size Based on Controlled Outside Diameter (DR)

• Iron Pipe Size Inside Diameter, IPS-ID (SIDR)

• Copper Tube Size Outside Diameter (CTS)

PE pipe is available in many forms and colors such as the following:

• Single extrusion colored or black pipe

• Black pipe with co extruded color striping

• Black or natural pipe with a co extruded colored layer
