PPR pipe production equipment is a special extrusion production line specially designed for random copolymer polypropylene (PPR) and modified materials (such as PPR steady-state tube materials), the core adopts the integrated process of "raw material dehumidification pretreatment - precise melt extrusion - vacuum shaping - uniform cooling - chipless cutting - intelligent winding". Its core principle is: in view of the characteristics of PPR with strong hygroscopicity, easy hydrolysis at high temperature, and hygienic grade, through deep dehumidification, precise temperature control and sanitary plasticization system, the PPR particles are melted and extruded through special molds, vacuum adsorption and shaping to ensure the accuracy of pipe diameter, and after cooling, it is cut into fixed-length pipes to meet the needs of hot and cold water transportation, heating, medical pure water and other scenarios.

Core Advantages and Applicable Scenarios

of the device 1. Core   Advantages

     ◦ Common advantages:

▪     Efficient integration: integrated production, 60% higher efficiency than traditional processes, and ≥ 98.5% scrap recovery rate;

▪     Precise and controllable: pipe diameter accuracy ±0.05mm, wall thickness uniformity error<2%, meeting the requirements of GB/T 18742-2023;

▪     Flexible adaptation: quick mold change (within 30 minutes), support customization of different pipe diameters and wall thicknesses, and some models are compatible with PE/PEX pipe production.

▪     Hygienic guarantee: no plasticizers, food-grade materials (such as 304 stainless steel) for equipment contact materials, in line with the sanitary permit for wading products, can transport drinking water;

▪     High temperature resistance adaptation: precise temperature control and plasticization system to ensure long-term use of pipes at 95°C, pressure resistance up to 1.6MPa, suitable for hot water transportation;

▪     Low energy consumption design: the comprehensive energy consumption per unit product is not higher than 72.67 kg of standard coal/ton, and the energy consumption of some high-speed models is reduced by 15%;

▪     Multi-layer co-extrusion capacity: Support the production of PPR steady-state tubes (outer PPR + inner oxygen barrier layer) to expand the application of heating systems.
