Both PPR and PERT pipes are produced using "plastic extrusion molding" and have similar core equipment (both require extruders, molds, cooling and shaping systems, etc.). However, due to differences in raw material characteristics, there are subtle differences in screw design, temperature control precision, and shaping methods, which directly affect the physical properties of the pipes (such as high temperature resistance and pressure resistance).
The core design of equipment (including production equipment and installation tools) for PPR and PERT pipes revolves around the material characteristics of the two pipes (PPR is highly rigid and requires high-temperature precision processing; PERT is highly flexible and allows for more flexible processing). These characteristics and advantages directly determine the production efficiency, product quality, and on-site construction reliability of the pipes.
Both PPR and PERT pipes are produced using a "plastic extrusion molding process," but due to differences in raw material melting temperature and physical properties (such as rigidity/flexibility), the production equipment is specifically optimized in terms of temperature control precision, screw design, and shaping methods, resulting in different characteristics and advantages.
PPR pipes (random copolymer polypropylene pipes) and PERT pipes (heat-resistant polyethylene pipes) are two commonly used plastic pipe materials in home decoration and engineering projects. They differ significantly in material, performance, and applicable scenarios. PPR pipes are made from polypropylene (PP) and a small amount of ethylene monomer through random copolymerization, and are currently the mainstream choice for hot and cold water pipes in home decoration, known for their "high temperature resistance and strong stability." PERT pipes are made from polyethylene (PE) through a special process, with their core advantages focusing on "flexibility and low-temperature crack resistance," making them more suitable for scenarios requiring high adaptability to pipe deformation.
