20mm Black PE100 HDPE Pipe

20mm Black PE100 HDPE Pipe is a tough, flexible and corrosion‑free polyethylene pipe supplied in convenient coils, designed for a wide range of water and infrastructure applications. Manufactured from high‑density PE100 material, it offers excellent durability, long service life and ease of installation on site.

This pipe is suitable for almost any non‑potable water application and can also be used for above‑ground potable water distribution networks, subject to local water authority approval. It is widely used across utilities, civil engineering and agricultural projects where reliability and flexibility are essential.

Formerly known as 20mm black MDPE or 20mm black alkathene pipe, this product is fully compatible with JDP push‑fit systems and supports both open‑cut and no‑dig installation methods, making it suitable for new installations and pipeline rehabilitation projects.

Features & benefits include:

• Supplied in 25m, 50m and 100m coils for reduced joints and faster installation
• Flexible and lightweight for easier handling on site
• Corrosion‑free PE100 HDPE material for long service life
• Suitable for non‑potable water and selected potable applications (subject to approval)
• Compatible with 20mm pipe inserts, compression couplings and push‑fit fittings
• Suitable for hydroelectric, geothermal, irrigation, aquaculture and marine outfall projects
• Manufactured to BS EN 12201‑2 and Regulation 31 compliant

Important Information

This product replaces what was previously known as 20mm black MDPE or 20mm black alkathene pipe.

Pipe dimensions are based on the PE water pipe specification BS EN 12201‑2 and are provided for guidance only. For potable drinking water applications, always check with the local water authority, as blue MDPE pipework may be required.
