HDPE Pipe Performance vs. Other Materials
Material strength, corrosion and chemical resistance, and leak-proof fusion joints contribute to HDPE’s 100-year product life and virtually maintenance-free performance. HDPE is lighter than steel, ductile iron or concrete for easier, faster and lower-cost installation, with a superior flow rate that lowers diameter requirements and material costs.
| Compare | HDPE Advantages | Why HDPE? |
|---|---|---|
| HDPE vs. Carbon Steel / Ductile Iron |
|
Steel and iron corrode, often causing leaks over time. HDPE is virtually corrosion free, with leakproof fusion joinery; HDPE’s much lighter weight offers easier installation and environmental benefits. Higher flow ratings reduce pumping and pipe diameter requirements in HDPE solutions. |
| HDPE vs. PVC |
|
Unlike HDPE, PVC is brittle, prone to crack runs, often requiring long section replacement. PVC uses bell & spigot joints; HDPE’s fusion joining system is longer lasting and leakproof. PVC has been known to have parts availability issues. |
| HDPE vs. Concrete / Clay |
|
HDPE is lighter weight and longer lasting, with significantly higher flow rates, crack resistance and leakproof joints, offering significant cost and environmental advantages over traditional concrete or clay pipe solutions. |
| HDPE vs. Fiberglass |
|
Fiberglass often requires expensive coatings to extend design life. HDPE offers a much more durable, simpler and less costly solution. |
| HDPE vs. PEX |
|
PEX, a cross-linked polyethylene, is not widely adopted; often requires testing prior to specific application, which increases complexity and cost. PEX is appropriate only for smaller diameter applications. |
