PP-R pipe extrusion production line process flow

The process flow of the PP-R pipe extrusion production line mainly includes the following steps:

Raw material preparation: First, the raw materials are mixed and screened to ensure the quality and uniformity of the raw materials.

Heating and melting: The mixed raw materials are fed to the extruder and melted by heating to prepare for subsequent extrusion molding.

Extrusion mold molding: The molten raw materials enter the mold through the extruder head, and after diversion and compression, they are compressed into a double-layer thin-walled tube, and then blown up by compressed air between the module and the sizing sleeve to form the initial molding of the inner and outer walls.

Cooling and shaping: The molded pipe is shaped by cooling water to ensure the stability of the size and shape of the pipe.

Traction cutting: After the continuous pulling pipe is demoulded, it is cut to obtain a pipe of a specified length.

Quality inspection: The cut pipe is quality inspected to ensure that it meets the quality standards.

Finished product stacking: The qualified pipes are stacked and ready to leave the factory. ‌

PP-R pipe extrusion production line ensures the dimensional accuracy and stable performance of the pipe. During the production process, strict quality control of raw materials and products is also required to ensure that the quality of the final product meets the standard requirements. ‌
