Useful Info:

Medium density polyethylene, also known as alkathene, is a tough and flexible thermoplastic which is used in the manufacture of water pipe, due to its high chemical resistance, and high prevention of algae, bacteria and fungi build-up.

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.

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.

Frequently Asked Questions:

Q: What's the difference between blue and black MDPE pipe?

A: Blue pipe is used for underground applications and, due to its UV resistance, black pipe is used above ground. However, only blue MDPE pipe is approved for use with drinking (potable) water?

Q: What does MDPE stand for?

A: Medium density polyethylene.

Q: Does MDPE pipe need inserts?

A: Strictly speaking, we would recommend any MDPE pipe up to 63mm is fitted with inserts (also referred to as liners) when being connected to fittings or valves, as this will help maintain the pipe's rigidity and provide a more reliable joint.

Q: Is alkathene the same as MDPE?

A: Yes, the terms alkathene and MDPE are interchangeable.
