A DWC pipe is a plastic pipe with an only difference is its internal and external surface. DWC stands for Double Wall Corrugated, which means the pipe has high strength and stiffness. Plastic, like HDPE, is generally used in the production of this kind of light weight pipe with a longer life. The pipe can be installed underground for sewerage and drainage. Industries, like wastewater treatment, also demand this kind of pipe for their treatment plants. This kind of pipe is segregated by colour as well. We have black and orange DWC pipes in sizes, ranging from 50mm up to 300mm.
