High Density Polyethylene

PNS ISO 4427:2002

A type of flexible plastic pipe used for fluid and gas transfer and is often used to replace ageing concrete or steel mains pipelines. It has a high level of impermeability and strong molecular bond make it suitable for high pressure pipelines.

- Light Weight

- Easy Handling

- Corrosion and Chemical Resistance

- Long service life span

- Heat-fused Joints

- Safe for Potable water

SDR Stands for "Standard Dimension Ratio" and this is used to rate pressure piping. The higher the SDR, the lower the pressure rating. SDR indicates the amount of pressure (in PSI) a HDPE pipe can withstand.

Facts about Standard Dimension Ratio (SDR)

- The Higher the SDR number, the thinner the HDPE Pipe.

- The Lower the SDR number, the thicker the HDPE Pipe.

PSI (Pound-force Per Square Inch) - It is the pressure resulting from a force of one pound-force applied to an area of one square inch.
