Characteristics of HDPE pipe production line
- The PE pipe production line is designed with a spiral die for HDPE and PP large-diameter thick walled pipes. This die has the characteristics of low melt temperature, good mixing performance, low mold cavity pressure, and stable production
- The PE pipe production line adopts proprietary technology for sizing and cooling system, using water film lubrication and water ring cooling to meet the requirements of HDPE and PP materials, ensuring stable diameter and roundness for high-speed production of thick walled pipes
- The PE pipe production line adopts a specially designed multi-stage vacuum sizing box to control the vacuum degree, ensuring the dimensional stability and roundness of HDPE and PP pipes. The extruder and traction machine are controlled by imported speed controllers, which have good stability, high accuracy, and high reliability
- The operation and time of the PE pipe production line are programmed and controlled by PLC, with a good human-machine interface. All process parameters can be set and displayed through a touch screen. A dedicated extruder for marking lines can be assembled to produce pipes with colored markings that meet national standards

Product Introduction
PE water supply pipes are made of specialized polyethylene as raw material and extruded by a plastic extruder. They are used in urban water supply networks, irrigation and water diversion projects, and agricultural sprinkler irrigation projects, and are particularly suitable for plastic pipes that are resistant to acid, alkali, and corrosion environments. Due to the use of hot melt and electric melting connections in PE pipes, the integration of the interface and the pipe material is achieved, and it can effectively resist the circumferential stress and axial impact stress generated by pressure. Moreover, PE pipes do not add heavy metal salt stabilizers, and the material is harmless, without scaling or bacterial growth, avoiding secondary pollution of drinking water.
Performance characteristics of PE/HDPE pipe
- Harmless hygiene: The material of the pipe is harmless and belongs to green building materials. It does not corrode or scale.
- Corrosion resistance: Polyethylene is an inert material that can withstand corrosion from various chemical media except for a few strong oxidants. It has no electrochemical corrosion and does not require an anti-corrosion layer.
- Easy connection: Polyethylene pipes are mainly connected by hot melt and electric melt, making the pipeline system integrated. It has good resistance to water hammer pressure, integrated fusion joints with pipes, and effective resistance to underground movement and end loads of polyethylene pipes, greatly improving the safety and reliability of water supply and increasing water utilization efficiency.
- Low flow resistance: The roughness coefficient of the inner wall of the polyethylene water supply pipe does not exceed 0.01, which can effectively reduce water supply consumption.
- High toughness: Polyethylene water supply pipes are a type of pipe with high toughness, with a fracture elongation rate generally exceeding 500%. They have strong adaptability to uneven settlement of the pipe foundation and are excellent in seismic performance.
- Excellent flexibility: The flexibility of polyethylene pipes enables them to be coiled and supplied in longer lengths, avoiding a large number of joints and fittings and increasing the economic value of the material for pipelines.
- Long service life: The safe service life of polyethylene pressure pipelines is over fifty years.
