DWC (Double Wall Corrugated) fabrication fittings are specialized components used mainly with DWC pipes for drainage, sewer, cable protection, and utility networks. Their key specialties include:
Dual-layer strength
Corrugated outer wall for high ring stiffness and load-bearing capacity
Smooth inner wall for excellent flow efficiency and low friction
Custom fabrication
Can be fabricated into bends, tees, reducers, manholes, inspection chambers, and special connectors
Ideal for non-standard layouts and complex site conditions
High durability
Resistant to corrosion, chemicals, abrasion, and soil aggressiveness
Long service life compared to RCC or metal fittings
Leak-proof joints
Designed for rubber ring joints, welded joints, or couplers ensuring tight sealing
Minimizes infiltration and exfiltration
Lightweight & easy installation
Easier handling and faster installation than traditional materials
Reduces labor and equipment costs
Excellent load & impact resistance
Performs well under heavy traffic loads and buried conditions
Versatile applications
Stormwater and sewer systems
Underground cable & telecom ducting
Industrial effluent and drainage systems
Cost-effective & low maintenance
Lower installation and lifecycle costs
Minimal maintenance over time
