Professional FAQ: Technical Insight on DN500 HDPE Doule Wall Corrugated Drain Pipes

1. What material is used in the production of DN500 HDPE doule wall corrugated drain pipes?

They are fabricated from high density polyethylene (HDPE) resins, typically PE100 or PE80 grade, in full compliance with ISO 4427 and ASTM D3350 standards.

2. What is the significance of SN (Ring Stiffness Number), and which classes are available?

SN numbers (e.g., SN8, SN10, SN12.5 kN/m²) indicate pipe wall’s resistance to soil and external pressures. DN500 HDPE doule wall corrugated drain pipes are most commonly provided in SN8–SN12.5, enabling robust underground applications.

3. Are these pipes suitable for pressurized flow?

No. DN500 HDPE doule wall corrugated drain pipes are engineered for gravity drainage (non-pressure scenarios) such as surface water or sewers.

4. What are the installation and connection methods?

They use integral socket/spigot joints with elastomeric rubber gaskets (per EN 681-1), allowing push-fit assembly and excellent leak resistance. Installation follows ASTM D2321 and EN 1610 methodologies.

5. What is the expected service life under standard operating conditions?

Generally, 50 years or more when correctly installed, thanks to polyethylene’s immunity to rust, scaling, and aggressive soils (Journal of Cleaner Production).

6. Which international standards are these pipes compliant with?

EN 13476-3 (Europe), ISO 21138 (international), and ASTM F2648/D3034 (USA) are commonly met. HORON INTERNATIONAL pipes also pass rigorous in-house tests.

7. How does HDPE compare to concrete or steel for large diameter drainage?

HDPE pipes offer dramatic weight reduction (up to 80% lighter), improved flow due to smooth walls, are inert to corrosive chemicals, and are easier to transport and handle (PPCA).
