HDPE Double Wall Corrugated Pipe | High Ring Stiffness Pipe for Municipal Sewage, Rainwater Drainage & Road Construction
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.
Application Scenarios
Urban municipal rain & sewage separation projects, highway subgrade drainage, airport & port drainage pipelines, residential community sewage systems, tunnel underground water collection, chemical park wastewater discharge, farmland garden flood drainage, underground parking lot drainage network
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"
Application Areas
1. Sewers and drainage
2. Front eaves drainage for balconies and other residential units in real estate projects
3. Peripheral drainage systems for commercial, industrial units, and independent factories
4. As sump pits in underground drainage systems for roads, highways, open spaces, stadiums, retaining walls, or parking lots.
5. As sump pits and drainage in groundwater systems, and under sludge drying beds in sewage treatment plants.
