High-density polyethylene (HDPE) pipes are widely used in sewage, water supply, drainage, and water transportation due to their high strength, low temperature resistance, corrosion resistance, non-toxicity, and wear resistance. HDPE pipes are gradually replacing traditional materials like steel and cement pipes in the market, especially because they are lightweight, easy to install, and move, making them a preferred choice for new materials.
Specifications include diameters of 315, 355, 400, 450, 500, 560, 630, 710, 800, 900, 1000, 1200, 1400, and 1600 mm. The nominal pressure for PE-6 is 0.32MPa~1.0MPa, for PE-80 is 0.4MPa~1.25MPa, and PE-1C is suitable for large diameter and high-pressure water supply projects.

Installation Instructions
There are various connection methods for polyethylene pipes, such as hot melt, electrofusion, flange, and steel-plastic transition joints. The selection depends on pipe diameter, working pressure, and usage environment. Hot melt involves heating the connection area under pressure until it melts and connects. Electrofusion uses specialized fittings with embedded resistance wires to heat and fuse the connection area. Flange connections involve securing with bolts and nuts, suitable for connecting polyethylene pipes to metal pipes, valves, and meters.
1. Excellent health performance: No heavy metal salt stabilizers are added, non-toxic material, no scaling layer, and no bacterial growth, effectively preventing secondary pollution of urban drinking water. 2. Superior corrosion resistance: Resistant to various chemical media, except for a few strong oxidizers, and no electrochemical corrosion. 3. Long service life: Can be safely used for over 50 years under rated temperature and pressure conditions. 4. Good impact resistance: High toughness and impact strength, can withstand heavy loads without breaking. 5. Reliable connection performance: High strength of hot melt or electrofusion joints, not affected by soil movement or crustal movement. 6. Good construction performance: Lightweight, simple welding process, easy construction, and low comprehensive project cost.
