The HDPE pipe for water supply is a new type of plastic pipe product made from high-quality polyethylene resin as the main raw material, with necessary additives such as antioxidants and ultraviolet absorbers, and processed through extrusion by an extruder.
PE resin is a polymer made from ethylene monomer. Due to different polymerization reaction conditions such as pressure and temperature during the polymerization process, resins of different densities can be obtained, which are classified as high-density polyethylene, medium-density polyethylene, and low-density polyethylene. When processing different types of PE pipes, different grades of resin are selected based on their application conditions, and different requirements are also applied to extruders and molds.
The HDPE pipe for gas adopts the most advanced polyethylene pipe extrusion production line, using high-performance imported polyethylene resin specifically for gas pipelines as the main raw material, with necessary additives such as antioxidants and ultraviolet absorbers, and is processed through extrusion to form a new type of product.
At the same time, the production line is equipped with a fully automatic computer control system, including an ultrasonic scanning device, meter-by-meter measurement control system, and wall thickness monitor, to dynamically control the product during the production process and ensure the production quality of every meter of pipe.
The PE pipe for coal mine underground use (PE mining pipe) is used for gas drainage, water supply and drainage, and spraying in coal mine underground. This product is a pipe for underground coal mine use, made from polyethylene as the main raw material, with suitable additives, and formed through extrusion. It is mainly suitable for gas drainage in coal mine underground boreholes. The PE pipe for coal mine underground can also be used for ventilation and drainage in underground coal mines.
The HDPE steel belt reinforced spiral corrugated pipe is a structural wall pipe made by winding and forming a composite of PE and steel belt, developed by adopting advanced foreign composite technology for metal-plastic pipes. The pipe wall structure consists of three layers. Through a unique manufacturing process, the steel belt is integrated with high-density polyethylene.
This allows the pipe to have both the flexibility of plastic pipes and the rigidity of metal pipes. By using U-shaped steel belt composite PE material, the ring stiffness of the pipe is significantly improved without increasing cost. Under the same weight, its strength is much higher than that of wound pipes and Krah pipes. It solves a series of problems such as heavy loads. The advantages of large-diameter steel belt pipes are more apparent. Currently, the pipe diameter ranges from 300mm to 3000mm, with ring stiffness maintained above 12.5KN/m, lighter in weight and stronger in performance compared to steel pipes and other plastic pipes.
The HDPE double wall corrugated pipe is a new type of lightweight pipe made from high-density polyethylene, with characteristics such as light weight, high pressure resistance, good toughness, fast construction, and long service life. Its excellent pipe wall structural design greatly reduces costs compared to other structural pipes. Moreover, due to its convenient and reliable connection, it is widely used both domestically and internationally. It has been largely replacing concrete pipes and cast iron pipes.
