It seems like you're asking about what "DWC pipe" contains or refers to.
DWC (Double Wall Corrugated) pipe is a type of plastic pipe commonly used in applications like drainage systems, sewage systems, and telecommunications. It typically consists of two layers:
Outer Layer (Corrugated): This is the thicker, ridged outer layer, providing durability and strength. It's designed to resist crushing and physical damage.
Inner Layer (Smooth): The smooth inner layer allows for efficient flow of liquids or gases, reducing friction and making it ideal for drainage.
These pipes are often made from materials like HDPE (High-Density Polyethylene) or PVC, which makes them resistant to corrosion, chemicals, and weather conditions.
Is this what you're referring to, or are you asking about something else in relation to DWC pipe
