It is used in mine hydraulic support, oil field development, engineering construction, lifting and transportation, metallurgical forging, mining equipment, ships, injection molding machinery, agricultural machinery, various machine tools, and mechanization and automatic hydraulic systems in various industrial sectors to transport materials with certain pressure and temperature. Petroleum-based (such as mineral oil, soluble oil, hydraulic oil, fuel oil, lubricating oil) and water-based liquids (such as emulsion, oil-water emulsion, water), etc. and pipelines for liquid transmission.
The oil pipes used in the coal industry mainly include hydraulic support hoses. In recent years, the pressure requirements of hydraulic supports in some coal mines have been increased, and some steel wire braided hoses cannot meet their performance requirements, and it is required to use steel wire wound oil pipes instead. In addition, in order to prevent coal dust pollution and improve production safety in the process of underground coal mining, the variety of coal mine tubing has been increased, such as coal seam water exploration and sealing device telescopic tubing, which is used to inject water into coal seams before fully mechanized mining in coal mines. , grouting and other operations. According to reports, domestic manufacturers have already produced it, and it has been tried by more than a dozen coal mines, and can replace similar imported products.
In the 21st century, China's offshore oil development strategy proposes to focus on the development of offshore and shallow oil fields. Therefore, the petroleum industry requires the use of shallow-sea oil pipelines in addition to drilling oil pipes and vibrating oil pipes. Shallow sea submarine oil pipelines have been produced in China, but floating or semi-floating oil pipelines and deep sea submarine oil pipelines still rely on imports. With the implementation of China's offshore oil development strategy, the requirements for oil pipeline performance in offshore oil exploration will continue to increase.
