PE100 Water Supply Pipe

High-Density Polyethylene Piping System for Potable Water & Municipal Applications

Product Overview

The PE100 Water Supply Pipe is a high-performance piping system manufactured from PE100 (Polyethylene, Grade 100), the latest generation of high-density polyethylene engineered for superior pressure resistance, long-term durability, and exceptional environmental stress crack resistance. Designed for potable water distribution, municipal water mains, industrial fluid transport, and irrigation systems, PE100 pipes offer a reliable, cost-effective alternative to traditional materials such as ductile iron, steel, and PVC. With a proven service life exceeding 50 years and unmatched resistance to corrosion, chemical attack, and ground movement, PE100 has become the global standard for modern water infrastructure.

Material & Classification

PE100 is a high-density polyethylene (HDPE) material classified according to its Minimum Required Strength (MRS) of 10.0 MPa at 20°C for 50 years. This classification indicates the material's ability to withstand sustained internal pressure, making it suitable for demanding pressure pipe applications.

The homogeneous wall construction ensures consistent mechanical properties throughout the pipe, with no risk of delamination or layer separation.

Applications

Our PE100 Water Supply Pipes are widely used in:

• Municipal Water Distribution
  Primary water mains, secondary distribution networks, and transmission lines

• Potable Water Supply
  Residential, commercial, and industrial drinking water systems

• Industrial Fluid Transport
  Process water, cooling water, and chemical conveyance

• Irrigation Systems
  Agricultural, landscape, and golf course irrigation networks

• Fire Protection Systems
  Fire water mains and hydrant supply lines (where approved)

• Trenchless Installations
  Horizontal directional drilling (HDD), pipe bursting, and slip lining for pipeline rehabilitation

• Water Treatment Plants
  Intake, discharge, and process lines

• Seawater Intake & Outfall
  Corrosion-resistant piping for marine applications

• Mining & Slurry Lines
  Abrasion-resistant fluid transport

Installation Methods

PE100 pipes offer multiple installation options, providing versatility for diverse project requirements:

1. Butt Fusion Welding
The most common joining method for PE100 pipes. Pipe ends are heated using a thermostatically controlled fusion machine, then pressed together under controlled pressure to form a homogeneous, fully restrained joint that matches the strength of the pipe.

2. Electrofusion Welding
Electrofusion fittings contain embedded heating coils. The pipe is inserted into the fitting, and an electrical current is applied to melt the material, creating a permanent, leak-proof connection. This method is ideal for repairs, tie-ins, and confined spaces.

3. Mechanical Connections
Flanged adapters, compression fittings, and transition fittings are available for connections to valves, pumps, and other piping materials.

Technical Specifications

Sizes & Dimensions

PE100 pipes are available in a wide range of diameters to suit diverse applications:

SDR = OD / wall thickness; lower SDR indicates higher pressure rating

Quality Assurance

All PE100 water supply pipes are manufactured under strict quality control systems in accordance with international standards. Our products undergo rigorous testing for:

• Hydrostatic pressure resistance at elevated temperatures

• Long-term creep rupture strength (extrapolated to 50+ years)

• Environmental stress crack resistance (ESCR)

• Melt flow index and material homogeneity

• Dimensional accuracy and wall thickness uniformity

• Carbon black dispersion and UV resistance

• Oxidative induction time (OIT)

• Compliance with drinking water safety standards

Compliance with applicable industry specifications ensures consistent quality, safety, and reliable performance across diverse water infrastructure applications.
