Useful Info:

Medium density polyethylene, also known as alkathene, is defined by a density range of 0.926-0.940 g/cm3 making it a thermoplastic which is tough and flexible. It is suitable for industrial applications with benefits over steel pipework including installation time and its immunity to corrosion.

MDPE has good shock and drop resistance properties, it is lightweight, is not notch sensitive, has excellent resistance to chemicals and stress cracking, and is designed to protect against surge and fatigue conditions. It provides a cost-effective solution for creating reliable water transportation systems.

MDPE pipe is typically used for transporting both water and gas, but the pipe in this section is only suitable for the distribution of water, including clean potable water for human consumption, waste water, general purpose water transportation, drainage and sewerage. For pipes suitable for the transportation of natural and LPG gas, please visit our Gas page.

MDPE is renowned for its good resistance to chemical attack. It does not rot, rust, pit, corrode or lose wall thickness through chemical or electrical reaction with the surrounding soil, nor does it normally support the growth of, or is affected by algae, bacteria or fungi. It is not resistant to certain oils, organic solvents, halogens and acids, depending on the concentration, temperature and pressure.

Our MDPE pipe is available in blue for below ground, and black for above ground applications.

For MDPE pipe dimensions and sizes, visit the relevant blue or black pipe section.

Pipestock are one of only a few suppliers who stock the Protecta-Line range of MDPE barrier pipes, as developed by GPS PE Pipe Systems.
