Zhenjiang Rongcheng Pipe Industry Co., Ltd. was established on January 5, 2006. It is a national high-tech enterprise and a professional production base for various plastic pipes (PE, UHMW-PE, FRPP, PPH, PVC, CPVC, MPP, etc.), HDPE pipes, HDPE fittings, HDPE valves, FRPP pipes, FRPP fittings, FRPP valves, FRPP tanks, PPH pipes, PPH fittings, PPH valves, PVDF pipes, PVDF fittings, PVDF valves, and PPH sheets. The company covers an area of 3,600 square meters and owns nearly 100 million yuan in assets. It has 10 pipe production lines, 5 fitting production lines, and a variety of molds including butt-welded elbows, socket-welded elbows, 45° elbows, butt-welded tees, socket-welded tees, gaskets, butt-welded flanges, socket-welded flanges, blind plates, and reducers. There is also one sheet production line, enabling the production capacity of over 4,000 tons of various anti-corrosion products. The maximum production diameter of pipes reaches 1,200 mm, while the maximum production width of sheets can reach 2,400 mm, with no limit on length. The company boasts strong technical capabilities, with 28 professional technicians, including 6 senior engineers, 6 assistant engineers, and 10 technicians. In 2006, the company obtained ISO9001 Quality System Certification, ISO14001 Environmental System Certification, ISO45001 Occupational Health and Safety System Certification, CMMI Certification, and IEC7001 Information Security System Certification. The annual designed production capacity is 1,200 tons, and the promised yield rate of products leaving the factory is 99.9%. The company is equipped with professional testing equipment and full-time quality inspection personnel to conduct comprehensive multiple tests. A full-process quality control system has been established, covering raw material procurement, production processing, process management, finished product inspection, and delivery. The raw material inspection protocol specifies that particle appearance is evaluated according to SH/T 1541-2006, mass flow rate of the melt is based on GB/T 3682.1-2018, tensile properties follow GB/T 1040.2-2006, melt flow rate is determined by GB/T 3682-2000, yield tensile strength is measured according to ISO527, yield elongation rate is based on ISO527, and thermal deformation temperature is assessed using ISO75/B standards. One sample (1.2 m per sample) of each specification is sent to third-party authoritative institutions for inspection reports. In 2006, the company obtained the “National Mine Safety Mark Certificate” issued by the National Mine Product Safety Mark Office. The company’s PE water distribution pipes received the “Sanitation Permit” for drinking water issued by the national health department. The company has also secured multiple invention patents, including a degassing tower, a mixing and stirring device for producing polyethylene materials for PE pipes, a rapid welding device for high-temperature resistant PP pipes, and a water-cooling device for PP pipes with its usage method. Additionally, it has patented a composite flame-retardant board, a silicon core pipe, a flame-retardant board, a wire protection sleeve, wear-resistant ultra-high-molecular-weight polyethylene pipes, a reinforced plastic pipe, a plastic pipe connector, an ultra-high-molecular-weight polyethylene pipe for chemical plants, a spray pan, a steel-plastic composite pipe, an MPP bellows, an MPP power pipe, a connection elbow used for connecting polyethylene pipes, a cutting device for PE pipes, a pressure testing device for PE pipes, a steel-plastic flange for connecting PE pipes, a PE pipe with inner wall cleaning function, a quick-release power pipe support, an auxiliary support device to improve the precision of PP pipe cuts, a positioning clamping tool for PP pipes, and a large-scale PE pipe handling and clamping device. The pipes produced by the company feature high technical content, superior performance, low overall cost, and long service life. The FRPP glass fiber-reinforced polypropylene pipe fittings are manufactured in accordance with the standards of the Ministry of Chemical Industry (HG20539), while the homopolymer polypropylene β-PPH pipe fittings are produced according to the standard QB-T5099-2017. The PE polyethylene pipe fittings are produced in compliance with the standard GB/T13663-2018. The PVDF polyvinylidene fluoride pipe fittings are produced according to the standard ISO1031. The pipe production design is innovative, the structure is reasonable, and the manufacturing process is advanced. Using single-extrusion molding, the products exhibit high strength, corrosion resistance, good airtightness, long service life, and easy installation and maintenance. The fully plastic valves made of FRPP, PPH, and PVDF are essential components for controlling the flow of corrosive media in chemical pipelines. The types of valves include ball valves, butterfly valves, check valves, diaphragm valves, and stop valves. All these valves feature simple structures, low fluid resistance, good sealing performance, and strong anti-corrosion properties.

A strict quality control system has enabled the company’s products to gain widespread recognition in the market due to their high stability, cost-effectiveness, and durability. The repeat purchase rate and customer reviews have consistently ranked at the top of the industry.

Adhering to the principle of “integrity as the foundation, technological innovation,” the company continuously introduces and adopts advanced plastic production technologies and equipment from renowned foreign enterprises. It also works closely with multiple domestic research institutions and has signed long-term cooperation agreements with Jiangsu University. The company recruits scientific and technical talents, establishes the “Science Research” base, and develops high-tech products such as anti-static flame-resistant PE pipes, fiber-reinforced polypropylene, ultra-high molecular weight polyethylene pipes and fittings, independently.
