Introduction of reinforced thermoplastic pipes
The reinforced thermoplastic pipe is a composite pipe which use reliable high strength materials (such as glass fiber, aramid fiber, carbon fiber, steel wire, steel belt, etc.) to strengthen the traditional thermoplastic pipe. It combines the unique advantages of thermoplastics such as flexibility, corrosion resistance and abrasion resistance with the high strength of the reinforcing material. RTP was originally developed in the 1990s as a replacement for medium pressure steel tubes to meet the growing demand for corrosion resistant pipes in the oil and gas industry (Corrosion of steel pipes costs the oil and gas industry billions of dollars every year). In the past few decades, such pipelines have been used by oil companies and oil service companies as a standard solution to replace steel pipes. It is widely used all over the world, especially in the Middle East.
China has been very active in reinforced thermoplastic pipes (RTP) and started early. The past 10 years can be said to be the exploratory period and incubation period of China's RTP. Through exploration and continuous development, RTP has been applied to liquid injection pipes and gathering and transportation pipes of onshore and offshore oil and gas fields in China's oil and gas industry, which has opened up a large market. At the same time, RTP has been successfully applied in the fields of urban and rural water transportation, industrial and mineral fluid transportation, brine field transportation, submarine pipeline, and hot spring utilization in China. Through independent innovation, China has accumulated a lot of experience and lessons from foreign technology. At present, all kinds of RTP production technology, machinery and equipment, special materials, and laying construction conditions have preliminary supporting, with the basic conditions to accelerate the development and growth. It is expected that the next ten years will be the development period and growth period of China's RTP.
