HDPE pipes for sale
HDPE (High-Density Polyethylene) is a thermoplastic with a high level of impermeability and strong bonds between molecules. As a result, it is used for pressure pipelines. It is soft and bendable and is suitable for both fluid and gas transfer. HDPE is resistant to impacts and with it, you do not have to worry about damages on the exterior. HDPE is safe for drinking water so much so that some countries have HDPE jugs for milk.
HDPE VS PVC
How is HDPE made?
It is made under extremely controlled conditions. During a process called cracking petroleum is heated to produce ethylene gas. The gas molecules then combine to form polymers which will result in polyethylene. The polyethylene granules are then made by putting the sludgy polyethylene into a series of moulds. By the end of the moulding process, different forms of HDPE would have been produced. The technology used by most manufacturers is called the Hoechst Slurry Polymerisation Technology which
What does PE100 mean for HDPE pipes?
It refers to the class of HDPE, 100 will be referring to the Minimum Required Strength(MRS) which is 10.0Mpa. The most common standards are PE80 and PE100. PE120 will be the grade after PE100 but it is still being developed.
How do you join HDPE?
There are a number of ways of joining HDPE, these include, using mechanical parts such
as clamps or compression fitting flanges or using heat in the form of welding. The welding used for HDPE include, extrusion welding, butt welding, socket welding, and electro-fusion welding. Butt fusion because it is cheap and easy to perform is the widely used method.
Notable Facts on HDPE
• It can be recycled
We stock SABS spec HDPE pipes from 16mm up to 630mm with pressure range from PN4 up to PN34.
HDPE Pipes are available in rolls, or 6m lengths.
Our HDPE pipes are chemically inert and unaffected by soil conditions. They can be fusion welded, ensuring absolutely leak free systems.
