PE water supply pipe is mainly made of food-grade virgin HDPE resin mixed with antioxidants, UV stabilizers and other additives. This extruded high-performance pipe ensures safe and pure drinking water, mainly used for urban & rural tap water transmission, community water supply, landscape irrigation and factory purified water pressure delivery.

A: Remove sharp stones at the trench bottom and lay a 10cm fine sand cushion; backfill fine soil or sand symmetrically in layers within 50cm on both sides and above the pipe, then compact.
A: Advantages: Light weight, good toughness, settlement resistance, corrosion resistance and low cost.
Disadvantages: Poor high-temperature resistance (prone to creep under long-term exposure above 40℃); aging under long-term outdoor exposure, buried installation is required.
A: Pure PE pipe for low pressure, small diameter and limited budget;Steel wire mesh skeleton composite pipe for DN110 and above, 1.6MPa high pressure and long-distance large-flow delivery.
