There are many plastic pipe products, and different plastic pipe production equipment such as city water pipes, gas pipes, sewage pipes, agricultural sewage pipes, industrial chemical pipes, petroleum pipes, and electrical insulation pipes for communication are required. The equipment used to produce these pipes is basically the same, as long as it includes an extruder, a pipe extrusion head, a shaping device, a traction device, a cooling device, a traction device, a label printing device, a cutting and winding device, a flaring and a stacking device.
The model and specification of the pipe extruder should be selected according to the type of plastic used, the state of the material, and the size of the product. Selection principles should be considered in terms of extrusion quality, production efficiency, energy consumption, machine life, reliability, general purpose or specificity. At present, the extruder produced by various plastic machinery factories in China has formed a series, and the diameter of the extruder screw capable of producing pipes is 30-200mm. If a single-screw extruder is used for production, the diameter of the plastic pipe can be controlled at 30% -130% of the screw diameter, and when a parallel twin-screw or conical twin-screw extruder is used, the pipe diameter can be controlled at 45 Within the range of% -450%.
