MDPE Pipe

Medium Density Polyethylene (MDPE) pipe is a robust and reliable solution for water distribution, offering excellent resistance to shock, impact, and environmental stress cracking. Commonly used for both new installations and the replacement of outdated lead pipework, MDPE is non-toxic, durable, and microbiologically inert under standard conditions. Available in blue for below-ground potable mains water and black for above-ground general water applications, MDPE provides a safe, long-lasting infrastructure solution for residential, commercial, and industrial settings.

• Potable Water Distribution: Approved for mains water conveyance below ground (blue) and general water systems above ground (black).
• Lead Pipe Replacement: Safe, non-toxic alternative for older domestic plumbing systems.
• Agricultural & Irrigation Systems: Resists chemical and microbial attack in rural installations.
• Industrial Water Conveyance: Suitable for transporting non-aggressive fluids in controlled environments.
• Geothermal Piping Systems: Recognised use in ground source heat pump applications (as per MSDS documentation).

• Storage & Handling: Store away from direct contact with oxidising agents. Avoid excessive heat and direct sunlight for extended periods (particularly for blue pipe).
• Pipe Cutting: Cut with suitable plastic pipe cutters or fine-toothed saws. Ensure ends are clean and square.
• Jointing Method: Typically joined using compression fittings or electrofusion welding (specialist tooling required). Ensure pipes are free from dust and debris before jointing.
• Safety Considerations: Wear gloves and eye protection during cutting or jointing. Use dust masks if fine particles are produced during cutting. Provide adequate ventilation when using heat-based jointing methods.
• Commissioning: After installation, flush the system and pressure test according to site requirements and local regulations. Confirm full sealing of all joints before final backfilling.
