The hottest fiberglass pipeline will shine brightl

Glass fiber reinforced plastic pipes will shine brightly. The development of composite materials has promoted a great revolution in the material industry. The birth of glass fiber reinforced plastic pipe (GRP pipe for short) marks the rise of non-metallic pipes in the material industry, and also indicates that the application field and market of non-metallic pipes in national economic construction will continue to expand and become broader

glass fiber reinforced plastic pipe is a new type of composite material pipe, which is mainly made of glass fiber yarn as reinforcement and resin as matrix, and is widely used in many fields. With the popularization and application of glass fiber reinforced plastic pipe, sand filled glass fiber reinforced plastic pipe (abbreviated as RPMP) has appeared. This kind of pipe not only improves the rigidity of the pipe in terms of performance, but also reduces the cost of the pipe

current situation of glass fiber reinforced plastic pipes

glass fiber reinforced plastic pipes are widely used in the construction industry. In recent years, most of the pipes used in new urban water supply projects in China are metal pipes and prestressed reinforced concrete pipes. As metal pipes need to be treated with anti-corrosion treatment, long-distance pipeline anti-corrosion not only increases the cost, but also the quality is difficult to guarantee; Prestressed reinforced concrete pipes are prone to explosion, which can not meet the load requirements of aviation and aerospace, pipe leakage and other quality problems, and the energy-saving effect is poor

GRP pipes are composed of inner liner, structural layer and outer protective layer. The inner liner of the pipe contains rich resin, which is corrosion-resistant and smooth on the inner wall. The friction coefficient of the transmission medium is small. The structural layer is glass. In 2010, the world's medical device industry was composed of 27000 medical device companies, which were reinforced with glass fiber. It is a stress-bearing layer bearing all loads, and it is safe and reliable to use

compared with other pipelines such as metal pipelines, FRP pipelines have low running resistance and energy consumption when transporting media. When the water delivery volume is the same, the diameter of the required FRP pipe can be at least one grade smaller. If pipelines with the same pipe diameter are used to transport the same amount of water, the power consumption of FRP can be 30% - 40% lower than that of steel pipes, cast iron pipes and cement pipes, or the transmission capacity can be increased by more than 20% under the same transmission energy consumption. The quality of FRP pipes is only 1/6-1/3 of steel pipes with the same diameter and length, 1/9-1/7 of cast iron pipes and 1/15-1/10 of concrete pipes, so the construction cost can be greatly reduced

transportation of glass fiber reinforced plastic pipes

Niu Xiaohui, an industry analyst of Shangpu consulting, believes that because glass fiber reinforced plastic pipes have many superior properties that cannot be replaced by other pipes, they are widely used in many fields such as corrosive medium transportation, sewage discharge, oil and gas transportation, agricultural irrigation, seawater transportation, circulating water of power plants, and urban water supply and drainage projects in chemical enterprises

oil field

FRP pipes for oil fields mainly include water injection pipes and oil well pipes. Since 1994, FRP pipes have been used in oil fields and have been widely used in Daqing oil field, Jilin oil field, Shengli oil field, Changqing oil field, Liaohe oil field and other large oil fields

chemical industry

since the 1990s, FRP pipes have been used more and more widely in the chemical industry. Although there have been problems in the use of FRP pipes in a few occasions, the overall situation is good. So far, it has been widely recognized in the field of chemical industry. Many domestic chemical enterprises or projects have selected a large number of FRP pipes, such as China Wuhuan Chemical Company, Yueyang Chemical Plant, Shanghai Petrochemical polyester plant, Jinhua Chemical Group, Suzhou chemical group, etc

water supply and drainage

in recent years, the use of FRP pipes in the field of water supply and drainage has shown an upward trend, and the market competition is fierce. Most of the FRP pipes used in the water supply field are medium and small caliber, and most of the pipes used in the drainage field are large and medium caliber. The pressure is generally very low when the water supply and drainage is not suitable for human habitation. Therefore, the (sanding) FRP pipes with good corrosion resistance, light weight, convenient installation, excellent hydraulic performance, but generally unable to withstand high pressure are particularly suitable for this field. With the development of China's economy and municipal construction, FRP pipes will be used more and more in this field

power station

FRP pipes are generally used as circulating water pipes, chemical water pipes, make-up water pipes, rainwater pipes and seawater desulfurization pipes in power stations (plants). At present, their use is in the ascendant. However, due to the limited number of power stations (plants) in China at this stage, and the many advantages of FRP pipes have not been recognized and accepted by the power industry, in the whole application of FRP pipes, This part of the market has not yet occupied a large share, but there is great market potential to be tapped
