HDPE hollow spiral pipe is a type of pipe made from high-density polyethylene (HDPE) that is formed through winding and welding. Due to its unique forming process, it can produce pipes with diameters of up to 3 meters, which is difficult to achieve with other manufacturing methods. High-density polyethylene (HDPE) has excellent fusion welding properties that not only ensure the forming process and product quality but also provide various reliable connection methods for construction, such as electric heat fusion welding and heat shrink connections. This is also an important reason why leakage is rare, and because of this, this type of pipe has unique environmental protection functions that other pipes do not possess, which offers very effective solutions for pollution prevention that people are currently concerned about. HDPE (high-density polyethylene) double-wall spiral large-diameter drainage pipe, made from HDPE raw materials and formed twice, has the following advantages: 1. Chemically stable, strong resistance to acids, alkalis, and salts, resistant to corrosion from sewage, wastewater, and chemicals, and resistant to decay from soil, with no rust. 2. Strong impact resistance and pressure resistance; the pipe wall uses a unique I-beam structure, allowing for significant elastic deformation without easy destruction, making it highly adaptable to any base. 3. Aging resistance; the pipe can withstand direct sunlight during storage and construction, and the design and manufacturing process of the pipe fully considers material deterioration factors over a 50-year period. 4. Wide temperature range applicability; can be used within a temperature range of -50°C to 60°C without freezing cracks or expansion leakage. 5. Lightweight; it is one-tenth the weight of cement pipes (for the same water transport efficiency), eliminating the need for large construction equipment. 6. Convenient connections. 7. Superior wear resistance; more wear-resistant than cement and steel pipes, with a service life of over 50 years. 8. Low raw material cost, and low construction, management, and maintenance expenses. 9. HDPE is a non-toxic material, harmless to land, recyclable, and is an environmentally friendly green product.
