Reinforced thermoplastic pipe (RTP pipe) has excellent performance and my country’s production strength continues to improve

Reinforced thermoplastic pipes, referred to as RTP pipes, are manufactured by extrusion molding, winding and weaving processes. They usually have a three-layer structure. The inner and outer layers are generally made of high-density polyethylene, polyvinyl chloride, polypropylene, polyvinylidene, etc. Thermoplastics such as vinyl fluoride are used as materials. The outer layer serves as a protective layer and has aging resistance and UV resistance. The middle layer generally uses aramid fiber, glass fiber, etc. as reinforcing materials.

According to the “2021-2025 Reinforced Thermoplastic Pipe (RTP Pipe) Industry In-depth Market Research and Investment Strategy Suggestions Report” released by the Industrial Research Center shows that there are various types of RTP pipe products. Due to the different materials of the inner and outer layers and the materials of the middle layer, there are certain differences in the performance of each product. Under normal circumstances, RTP pipes have the advantages of good flexibility, high pressure resistance, corrosion resistance, impact resistance, not easy to crack, long service life, long-distance pipe production, convenient transportation, and simple laying.

RTP pipe was first used in the UK in the mid-1990s. Since then, its application scope has expanded rapidly due to its excellent performance. At this stage, RTP pipes can be used as oil transmission pipelines, natural gas transmission pipelines, gas transmission pipelines, high-pressure water pipelines, hot spring water pipelines, special fluid pipelines, etc., and are widely used in petroleum, natural gas, chemical industry, agricultural irrigation, urban pipeline networks, Scenic spots and other areas.

RTP pipe is an excellent pipe with good flexibility, high pressure resistance and can transport materials over long distances. The market demand is constantly increasing. Compared with Europe, my country’s RTP pipe industry started late. It was not until 2009 that Nanjing Chenguang Composite Pipe Engineering Co., Ltd. introduced production lines from Germany that my country had production capabilities. Nanjing Chenguang Composite Pipe Engineering Co., Ltd. became the fifth company in the world with RTP pipe production capabilities. of enterprises.

After continuous efforts, the number of RTP pipe manufacturers in my country has begun to increase. In addition to Nanjing Chenguang Composite Pipe Engineering Co., Ltd., there are also Aerospace Chenguang (Fujian) Pipe Industry Technology Co., Ltd., Guangzhou Lijin New Technology Co., Ltd., and Shanghai Jwell Pipe Equipment Manufacturing Co., Ltd., Changchun Gaoxiang Special Pipe Co., Ltd., Jiangsu Liangguan High-tech Co., Ltd., Cangzhou Mingzhu Plastic Co., Ltd., etc. With the continuous accumulation of technology and experience, my country’s RTP pipe production line independent research and development capabilities continue to increase. Guangzhou Lijin New Technology Co., Ltd. independently developed my country’s first RTP pipe production line, breaking the monopoly of domestic technology by German companies.

Industry analysts said that pipeline transportation has the advantages of a wide variety of transportable products and low transportation costs, and has become one of the five major cargo transportation in my country. One of the ways is that oil, natural gas, and chemicals are its main transportation substances. According to data from the National Bureau of Statistics, my country’s pipeline oil (gas) pipeline mileage was 126,600 kilometers in 2019 and 134,100 kilometers in 2020, a year-on-year increase of 5.9%. Since 2015, the mileage of pipelines transporting oil and gas in my country has continued to increase, and is expected to maintain a growth trend in the next five years, which will benefit the development of my country’s RTP pipe industry.
