Material & Specifications

Key Advantages

• Leak-Free Joint System – Butt fusion and electrofusion welding create monolithic, fully restrained joints that eliminate leak points. Zero leakage significantly reduces water loss and non-revenue water—a critical advantage for municipal water networks.

• Corrosion & Chemical Resistance – Immune to electrochemical corrosion, rust, and chemical attack. No external coatings, cathodic protection, or internal linings required, reducing installation and lifecycle costs.

• Flexibility & Seismic Resilience – High flexibility allows the pipe to accommodate ground settlement, soil movement, and seismic activity without joint failure. Ideal for earthquake-prone regions and challenging terrains.

• High Flow Capacity – Smooth inner surface (Hazen-Williams coefficient C = 150) maintains consistent flow characteristics over time with no scaling, pitting, or biofilm accumulation.

• Lightweight & Cost-Effective – Approximately one-eighth the weight of steel pipe, enabling faster installation with reduced labor and equipment requirements.

• Long Service Life – Designed for service life exceeding 50 years with minimal maintenance, backed by extensive field performance data worldwide.

• NSF/ANSI 61 Certified – Meets international standards for potable water applications, ensuring safe drinking water quality with no leaching or contamination.

Applications

• Municipal water distribution networks

• Transmission mains for potable water

• Water treatment plant piping

• Rehabilitation and trenchless installation (slip lining, pipe bursting)

• Industrial water supply systems

• Rural and agricultural water supply

• Fire protection water mains

Connection Methods

Installation Methods

HDPE water pipes can be installed using:

• Open Trench – Conventional installation with fusion welding

• Horizontal Directional Drilling (HDD) – Trenchless installation under roads, rivers, and obstacles

• Slip Lining – Rehabilitation of existing deteriorated pipelines

• Floating or Submerged – River crossings and intake lines

Standards & Compliance

Our HDPE Water Supply Pipe is manufactured in compliance with:

• ISO 4427 (international standard for polyethylene piping systems)

• ASTM D3035 / D3350 (US standards)

• EN 12201 (European standard)

• NSF/ANSI 61 (certification for potable water safety)

Quality Assurance

All products undergo rigorous quality control, including raw material testing, dimensional verification, pressure testing, and visual inspection, ensuring consistent performance and full traceability.
