900~1200MM HDPE PIPE EXTRUSION LINE

This is a hunge HDPE pipe extrusion line that is used for manufacturing high-density polyethylene (HDPE) pipes with diameters ranging from 900mm to 1200mm. This extrusion line is designed to efficiently and precisely produce large-diameter HDPE pipes, which are commonly used in various applications such as water supply, drainage, and industrial piping.
The function of the HDPE pipe extrusion line is to take raw HDPE material, typically in the form of granules or pellets, and process it through a series of steps to form the final pipe product. The extrusion line typically consists of several key components, including two automatic vacuum loaders, a hopper dryer, a metric weighing systems, an extruder, a die head, a 1.5 meters vacuum calibration tank and a 10 meters vacuum calibration tank, three spray cooling tanks, a haul-off unit, a cutting machine, and a stacker. Each of these components plays a crucial role in the extrusion process, ensuring the production of high-quality, uniform HDPE pipes.
The extrusion process begins with the raw HDPE material being fed into the extruder by automatic vacuum loaders, where it is melted and homogenized. The molten HDPE is then forced through the die head to form the desired pipe diameter. As the pipe exits the die head, it enters the vacuum calibration tank, where it is shaped and cooled to maintain its dimensions and roundness. The shaped pipe will go through three spray cooling tanks for further cooling. The haul-off unit then pulls the pipe at a controlled speed, while the cutting machine precisely cuts the pipe to the desired length. Finally, the stacker collects and organizes the finished pipes for further handling and packaging.
