HDPE Pipe 1/2 Inch in Kenya

HDPE pipe 1/2 inch is high-density polyethylene water pipe in the 1/2 inch size, commonly sold as 20 mm outside diameter. This size suits household water connections, drip lines and small garden supplies.

It does not rust and handles ground movement. Therefore, it is a long-lasting choice for buried water lines.

What is HDPE pipe 1/2 inch?

HDPE pipe is high-density polyethylene pipe used for water mains, irrigation and borehole lines. It is tough, flexible and does not rust.

It is sized by outside diameter in mm and rated by pressure (PN). Joints are made by butt fusion, electrofusion or compression fittings. Because fused joints are as strong as the pipe, HDPE mains rarely leak at joints.

Key terms explained

HDPE: High-density polyethylene, a tough, flexible plastic used for water and gas pipes.
PE100 and PE80: Grades of polyethylene. PE100 is stronger, so pipes can have thinner walls for the same pressure.
PN rating: Pressure Nominal, the working pressure in bar, such as PN10 or PN16.
SDR: Standard Dimension Ratio: outside diameter divided by wall thickness. A lower SDR means a thicker, stronger wall.
Butt fusion: Joining two HDPE pipe ends by heating them and pressing them together.

Features and benefits

Does not rust, rot or scale.
Flexible, so it handles ground movement.
Tough and impact resistant.
Black pipe resists UV from sunlight.
Fusion or compression joints.
Straight lengths for neat mains and large sizes.
