Base Material: Same Polymer
Both pipe types are produced from HDPE (High-Density Polyethylene), which is a thermoplastic polymer in the polyethylene family.
Typical characteristics of HDPE include:
Density: 0.941–0.965 g/cm³
Excellent chemical resistance
Good impact strength
Corrosion resistance
Differences in Raw Material Grade
Although both are HDPE, water supply pipes usually require higher-grade materials.
HDPE Water Supply Pipes
Typical resin grades:
PE80
PE100
Sometimes PE100-RC (crack-resistant)
Requirements:
Certified drinking water safety
High hydrostatic pressure resistance
Excellent slow crack growth resistance
Long-term pressure performance.
HDPE Conduit Pipes (Cable Protection Pipes)
Conduit pipes are used for:
Electrical cable protection
Telecommunication conduits
Underground cable ducts
Material requirements focus more on:
Impact resistance
Crush resistance
Flexibility
Environmental stress resistance
Resin grades may include:
PE80
General pipe-grade HDPE
Sometimes recycled or blended materials (depending on standards)
