Recently, China's first independent research and development of "Flexible thermoplastic reinforced plastic pipe composite pipe" (RTP pipe) production technology and equipment successfully developed in Guangzhou, marking China's RTP pipe production technology has entered the international advanced ranks, in one fell swoop to the exclusive monopoly of German companies The international market situation.
It is understood that RTP pipe is a high-pressure plastic composite pipe, composed of three layers, the inner and outer layers are more than PE80 material, the middle layer is reinforced by reinforced composite material, the reinforcing material can be polyester fiber, aramid fiber or steel wire, etc. . As the RTP pipe realizes the packaging and transportation of large and medium-diameter high-pressure pipe into packages, the length of each roll ranges from 200 to 2000 meters. Compared with the previous supply of straight tubes of 6 to 9 meters in the medium and large diameter pipes, it not only reduces the transportation costs, More importantly, the connection between the pipe and the pipe is greatly reduced, and the reliability is greatly improved. However, the construction speed is increased by several dozen times, and the transportation and construction costs are reduced by about 70%. Therefore, the RTP pipe has been in many foreign countries. A large number of successful use in the fields of oil transportation and natural gas transportation. Prior to this, only one German company in the world was able to manufacture and produce RTP production equipment.
Guangzhou Lijin New Technology Co., Ltd. has invested heavily in RTP production equipment that has been successfully developed for 3 years. It has pioneered the world's leading one-step production process for RTP tubes and continuously produces 3 to 6-inch RTP tubes, avoiding the two-step process. The plastic inner tube repeats the winding and reel conveying process; the advanced chemical fiber reinforced material with a variety of structures is used for winding and reinforcing the pipe, so that the working pressure of the production pipe is increased to a maximum of 15 MPa or more. The equipment has independent intellectual property rights in RTP structural design, tape making equipment, four-layer winding technology, and process control software.
Some experts indicated that the successful development of RTP pipe production equipment is important for improving the level and economic efficiency of China's pipeline equipment manufacturing industry, promoting the construction of oil, natural gas, and tap water pipelines, promoting the development of green chemical building materials, and exploring the international market with high technology. significance.
