HDPE Water Supply And Drainage Pipe
1. Product Overview
HDPE (High-Density Polyethylene) pipes are lightweight, flexible, and corrosion-resistant plastic pipes widely used for potable water supply, drainage, irrigation, and industrial fluid transport.
Key Advantages:
✔ Corrosion-Free – Resistant to chemicals, acids, and alkalis
✔ Long Lifespan – 50+ years under normal conditions
✔ Leak-Free Joints – Heat-fused connections ensure perfect sealing
✔ Flexible & Durable – Withstands ground movement and pressure
✔ Cost-Effective – Lower installation & maintenance costs vs. metal pipes

5. Installation Methods
(1) Butt Fusion (Most Common)
Process: Heating pipe ends and pressing them together
Advantages: Strong, leak-proof, permanent joints
(2) Electrofusion (For Fittings & Repairs)
Process: Using electrically heated couplers
Advantages: Ideal for confined spaces
(3) Mechanical Joints (Flanges, Compression Fittings)
Process: Rubber-sealed connections
Advantages: No welding required, easy disassembly
