HDPE Double Wall Corrugated Culvert Pipe Durable 300 400 600 SN8 with Rubber Ring Connection Available for Sale
HDPE Double-Wall Corrugated Pipes are plastic drainage pipes/culverts. HDPE double-wall corrugated pipes are double-layered drainage pipes made of high-density polyethylene (HDPE). They are formed in one piece by extruding internally and externally using separate extruders. The inner wall is smooth and flat, while the outer wall is corrugated. The outer wall has a ring-shaped corrugated structure, forming a hollow layer between the inner and outer walls. This unique pipe structure results in high strength. The entire production process includes: extrusion-composite-molding-cooling-cutting-finished product.
1. It features lightweight, high ring stiffness, convenient construction, transportation, and installation, low installation cost, high UV resistance, and good flexibility. Compared to other pipes of the same diameter, HDPE double-wall corrugated pipes have a higher flow velocity due to their smooth inner wall.
2. HDPE double-wall corrugated pipes utilize a ring-shaped wall structure and optimized corrugated structure, giving the pipe greater strength and appropriate flexibility per unit weight, thereby improving raw material utilization.
3. Reliable connection, preventing leakage: HDPE double-wall corrugated pipes adopt a sleeve-reinforced design and are connected with sealing rubber rings, making the pipe connection more robust and reliable. Strict control of sleeve joint dimensions makes installation easier and leakage prevention more effective.
4. Complies with the standard "Buried Polyethylene (PE) Structural Piping Systems Part 1: Polyethylene Double-Wall Corrugated Pipes"
