The "Underground Artery" of Industrial

2026-01-06

In urban underground pipeline networks, a type of pipe manufactured using advanced winding technology is quietly transforming the landscape of traditional drainage and sewage systems. Through its unique I-beam structural design and hot-melt winding technology, the hollow-walled spiral wound pipe production line offers a more environmentally friendly and efficient solution for modern industrial wastewater drainage and construction projects.

Outstanding Performance in Industrial Wastewater Drainage

In the industrial sector, the hollow-walled spiral wound pipe has become the material of choice for drainage pipelines in industries such as chemicals, hospitals, and environmental protection, thanks to its excellent corrosion resistance. Made from high-density polyethylene (HDPE), the pipe boasts strong resistance to corrosion and chemical erosion, requiring no anti-corrosion treatment when transporting corrosive fluids or being laid in highly corrosive soil. Its performance significantly surpasses that of traditional pipes .

Industrial drainage pipes need to withstand the erosion of various corrosive media, where common pipes are prone to blockage, corrosion, and rupture. Due to their excellent corrosion resistance, resistance to acids, alkalis, and salt spray, hollow-walled spiral wound pipes can maintain long-term stable drainage function even in harsh environments . The Manning roughness coefficient Nof the pipe's inner wall is approximately 0.010. Consequently, the frictional resistance is low when conveying fluids, leading to a significantly higher flow capacity under the same conditions compared to concrete pipes
