HDPE Pipe Black Coils
What is Black HDPE Pipe Used For?
Black HDPE pipe coils are primarily used in non-potable water applications, including agricultural irrigation, industrial usage, and stormwater drainage. The black coils are particularly designated for applications where it's crucial to differentiate the piping used for non-potable water from that used for potable water systems.
Key Features
- Material Quality: The coils are manufactured from high-density polyethylene (HDPE) for diameters from 90mm to 180mm, ensuring durability and resistance to environmental stressors. Sizes 20mm to 63mm are made from medium-density polyethylene (MDPE), offering a balance of flexibility and toughness.
- UV Resistance: Black pigmentation provides excellent UV protection, making these pipes suitable for exposed installations.
- Flexibility and Ease of Installation: The coil design facilitates easier handling and installation, reducing the need for multiple joints.
- Pressure Capability: With a pressure capability of 10 bar, these pipes are adept for an extensive array of water supply needs.
- Environmental Consideration: HDPE is recyclable, aligning with green and sustainable practices.

Installation Overview for HDPE Black Pipe
Installing HDPE Black Pipe requires careful handling and adherence to best practices to ensure a durable and effective pipeline system. These pipes, designed for various non-potable water applications, can be installed both underground and above ground, benefiting from UV-resistant properties that make them suitable for exposed conditions.
Key Steps for Installation:
- Pre-Installation Checks: Inspect the pipe for any damage prior to installation. Ensure the trench and installation site are clear of debris and hazards.
- Uncoiling: Gently uncoil the HDPE Black Pipe, preventing kinks or stress, and handle it with care to avoid any damage.
- Pipe Placement: Lower the pipe into the trench or position it for above-ground installation, ensuring it is laid out straight without any twists.
- Joining: Utilise butt fusion or electrofusion for connecting pipe sections (mechanical fittings can be used up to 125mm), following meticulous cleaning and preparation of the ends to ensure robust joints.
- Backfilling (for underground installation): Carefully backfill the trench, compacting the soil around the pipe to provide stability and protect the pipeline.
- Pressure Testing: After installation, conduct a pressure test to verify the integrity of the pipeline and its joints.
- Final Inspection: Ensure the installation complies with all standards and the pipeline is free from leaks or any installation-related defects.
