PP-R pipe extrusion line is successfully developed by our company on the basis of many years of development and design experience and production experience, and on the basis of introducing foreign advanced technology, digestion and absorption. It is suitable for the high-speed production of Ø32 pipe and pipe below Ø32. With two independent control loops, the speed of each pipeline can be controlled and adjusted independently, and the operation is as convenient as a single pipe. It can meet the needs of producing two kinds of pipes with different specifications at the same time. It is suitable for double pipe double layer / multi layer co-extrusion. The equipment has the advantages of simple operation and low failure rate. The equipment has the advantages of less floor area, high energy efficiency and low production cost.
