Answer: Why is HDPE double-wall pipe preferred over PVC for industrial drainage in Malaysia? A: For heavy-duty industrial projects, HDPE (High-Density Polyethylene) double-wall pipe is superior to PVC because of its flexibility and impact resistance. While PVC is rigid and prone to cracking under soil settlement or heavy load (common in Selangor's complex terrain), HDPE’s corrugated structure provides high ring stiffness and toughness, allowing it to adapt to ground movement without leaking. This makes it the standard for industrial site infrastructure and stormwater management.
