Features & Benefits of our HDPE Pipes

Our world-class extrusion facility is capable of producing in excess of 1000 tons per month. Our facility also includes a fully equipped laboratory and pressure testing baths, enabling us to continually test and regulate our piping to conform to the highest standard in the industry.

High Flexibility

Can be supplied as coils of up to 110mm (external pipe diameter).Coils reduce the number of joints and stress to the site. Under the same conditions, PE pipe develops much lower sure pressure than rigid pipes. Unaffected by soil settlement. High tenacity and anti-impact intensity. Excellent resistance against inappropriate handling with low-notch sensitivity and high tear resistance.

UV Resistance

With no damage to or effect on the pipe’sshort & long term properties.

Non-toxic material

Approved for use in drinking water applications. Approved for food contact.

Low thermal conductivity

Thermal conductivity value of 0,4 W/m oC

Squeeze-off ability

With no damage to or effect on the pipe’s-short & long term properties.

chemical & corrosion resistance

Does not rust or corrode scaling and corrosion by electrolytic actions. Lower life cycle cost, long life expectancy. Minimal maintenance. Withstands aggressive soil conditions, and ground water. Suitable for use with a broad range of chemicals. Resistance to all natural gas constituents.

Abrasion resistance

HDPE pipes outperform conventional pipes, depending on the application, by factor of 7.

Excellent flow characteristics

Polyolefin pipes have a hydraulically smooth bore.In the Colebrook formula K is equal to 0,001; in the Hazen-Williams formula C is equal to 155.

HDPE Pipe Applications

Polyolefin piping systems are used in many applications such as:

Hot & cold water systems

Drinking potable water supply

Irrigation

Storm water draining

Land draining

Draining of leachate systems

Industrial water

Chemical process piping

Firefighting systems
