Ningbo Fangli Technology Co., Ltd. is a mechanical equipment manufacturer with over 30 years of experience in plastic pipe extrusion equipment, as well as new environmental protection and new materials equipment. Since its inception, Fangli has been committed to meeting user needs through continuous improvement, independent R&D in core technologies, and the digestion and absorption of advanced techniques. The company has developed PVC pipe extrusion lines, PP-R pipe extrusion lines, and PE water supply/gas pipe extrusion lines, which were recommended by the Chinese Ministry of Construction as replacements for imported products. Fangli has also been honored with the title of "First-class Brand in Zhejiang Province."
PPR (polypropylene random copolymer) is a type of tripropylene polyethylene, also known as random copolymer polypropylene pipe. It is joined using heat fusion and requires specialized welding and cutting tools. The material offers high plasticity, good thermal insulation, and a smooth inner wall surface. It is economically priced, typically ranging from RMB 6 to 12 per meter (for 1/2-inch pipes), excluding fittings. PPR pipes are commonly used in embedded wall installations or as buried pipes in deep well applications.
PPR pipes are moderately priced, exhibit stable performance, and offer heat resistance, thermal insulation, and corrosion resistance. Their smooth inner walls prevent scaling, and the pipeline system is safe, reliable, and impermeable, with a service life of up to 50 years. However, installation requires high technical expertise, and the use of specialized tools and trained professionals is essential to ensure system safety and integrity.
Five advantages of the PPR composite pipe production line:
I. The production line is equipped with a PLC control system, ensuring a high degree of automation and user-friendly operation.
II. Precise synchronous control technology ensures consistent and balanced operating speeds across all tractors.
III. The adoption of outer-layer co-extrusion technology enhances the interlayer bonding strength of the pipe.
IV. The line is fitted with internationally renowned argon arc welding equipment and a welding torch cooling system, ensuring long-term, continuous production.
V. The PPR composite pipe production line offers outstanding resistance to high pressure and high temperatures, and prevents delamination between the aluminum and plastic layers.
