DWC Corrugated Drain Pipe DN110–DN1200

Description

1. Product Overview

DWC Corrugated Drain Pipe DN110–DN1200 is a double-wall corrugated polyethylene drainage pipe engineered for efficient collection, conveyance, and management of stormwater, groundwater, and subsurface drainage. Its smooth inner wall promotes high flow capacity and reduced hydraulic resistance, while the corrugated outer wall provides high ring stiffness and resistance to external loads. Designed for demanding underground infrastructure, it offers a durable, lightweight, and cost-efficient alternative to conventional rigid drainage systems. Its broad diameter range supports applications from residential drainage networks to major municipal, industrial, and civil-engineering projects.

3. Core Industrial Applications

• Municipal Infrastructure: Stormwater drainage, road drainage networks, culverts, and urban water-management systems.
• Civil Engineering & Construction: Underground drainage for residential developments, commercial complexes, industrial parks, and infrastructure projects.
• Highways & Transportation: Roadside drainage, highway runoff collection, subsoil drainage, and infrastructure protection.
• Agriculture: Land drainage, field water management, and agricultural drainage networks.
• Industrial Facilities: Collection and conveyance of non-process wastewater, groundwater, and site stormwater.
• Mining & Large-Scale Earthworks: Subsurface drainage and controlled water conveyance in demanding terrain.
• Performance Advantage: The lightweight polyethylene construction simplifies handling and installation compared with heavier rigid pipe alternatives, while the corrugated exterior provides structural strength and the smooth inner wall supports efficient hydraulic performance.
• Cost Advantage: Reduced transportation, handling, installation, and maintenance requirements can contribute to lower total installed project costs.

4. Competitive Advantages

• Quality Consistency: Controlled extrusion and dimensional manufacturing processes support consistent wall geometry, stiffness, and hydraulic performance across production batches.
• Supply Reliability: Suitable for project-based procurement, infrastructure programs, and recurring bulk requirements across multiple diameter specifications.
• Logistics Capability: Lightweight construction enables efficient handling and optimized transportation compared with heavier conventional drainage materials.
• Price Competitiveness: Competitive material utilization and simplified installation can provide an attractive total-cost-of-ownership proposition for large-scale drainage projects.
• Durability & Sustainability: HDPE offers strong resistance to corrosion, moisture, and many common chemicals, while its long service life can reduce replacement frequency and associated lifecycle impacts.
• Technical Support: Product specifications, dimensional data, installation guidance, quality documentation, and project-specific technical support can be provided to support professional procurement and engineering requirements.
