Applications :

They are used for transporting drinking water and gas, fire extinguishing systems and irrigation systems.

Advantages :

In addition to what mentioned above in corrugated pipes we would like to list the following:

• Easy handling,  transporting  and storing.
• High chemical and temperature resistance.
• Impact and fracture resistance because of its flexibility.
• UV  resistance.
• Smooth surface prevents sediment.
• Good for cold weather and ice doesn’t affect.

Joining :

We have two techniques :

• But fusion
• Mechanical joints

Polyethylene systems offer significant advantages over ductile iron, steel and cement systems.

• Corrosion Resistance: Polyethylene is basically chemically inert Systems do not rust nor corrode and resist chemical attacks from aggressive soils. Doesn’t react to salt or acids.  No protective layer or finishing process is required.
• Leak Tight: Butt fused joints create a homogeneous system, the fusion welds as strong as the pipe. Therefore, unlike ring type joints or other mechanical jointing systems, there is no risk of leakage resulting from joint distortion.
• Optimum flow rates: Smooth inside pipe surface allow for a high Hazen-Williams C factor. C remains constant throughout the lifetime of the system due to an innate high resistance to scale and biological build-up. Polyethylene is biologically inert.
• Excellent Water Hammer Characteristics to withstand Surges: the inherent properties of Polyethylene allow the system to significantly lower the effects of surges compared to PVC and Ductile Iron systems.
• Flexibility: allows PE pipes to be coiled and supplied in lengths of up to 200m for small diameter pipes. This feature is one of the many contributors to cost savings during installation.
• Resistance to Geological Conditions: A Polyethylene system has inherent resistance to ground temperature fluctuations and earth instability.
• High strain allowance virtually eliminates failure due to freezing pipes.
• Capable of holding external/outside high pressures
• Easy to transport
• Safe to health

Dimensions:

• Diameters are from 20 mm up to 450 mm with different pressures from 6 bar to 25 bar according to ISO 4427.

• Diameters less than 63 mm are manufactured in coils with 100 m length or 200 m length, these diameters are jointed mechanically.
• Diameters up to 450 mm are manufactured in straight pipes with 12m length.

Thickness

According to bar.

Color

Black with four blue stripes.

All strict procedures are followed in order to control the quality of the

pipes for potable water as per the International Standard; ISO4427.
