Polyethylene (PE) Pipes & Fitting

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)


• High stretch capability. By this means, they provide easiness in assembly. Breaking strain is minimum 350%.

• Do not get affected from underground movements and not breakable.

• High impact resistance and crack-spreading resistance.

• Since their internal surface smoothness is low, it provides important advantages while selecting diameter in projecting.

• Appropriate to undersea installation, and do not get affected from sea water and sea movements.

• Due to linking method, no montage loss.

• Serves free-of-problem under nominal operational pressure for minimum 50 years.

• UV-light resistance.

• Do not get affected from harmful substances contained in the earth structure and having corrosive effects.

• Therefore, they do not require cathodic protection.

• Resistant against chemical substances.

• Do not change the smell and taste of the water, therefore it is sanitary.

Uses & Applications

PE pipe offers distinct advantages as a piping material:

• Light weight

• Flexibility

• Chemical resistance

• Overall toughness

• Longevity

These benefits make it an ideal piping material for a broad variety of applications such as potable water service or distribution lines, natural gas distribution, lawn sprinklers, sewers, waste disposal, and drainage lines. PE materials are generally resistant to most ordinary chemicals.

Polyethylene can be used in low temperatures without risk of brittle failure. Thus, a major application for certain PE piping formulations is for low-temperature heat transfer applications such as radiant floor heating, snow melting, ice rinks, and geothermal ground source heat pump piping.
