In what aspects are high-pressure hoses used

coal industry
The oil pipes used in the coal industry mainly include hydraulic support rubber pipes. The pressure requirements for some coal mine hydraulic supports have been increased, and some steel wire woven rubber pipes cannot meet their performance requirements, requiring the use of steel wire wrapped oil pipes instead. In addition, in order to prevent coal dust pollution during underground coal mining and improve production safety, the variety of oil pipes used in coal mines has been increased, such as the expansion oil pipe of the coal seam water probe hole sealer, which is used for water injection, grouting and other operations on the coal seam before the comprehensive mining of the coal mine underground working face. According to reports, domestic manufacturers have produced and tested it in more than ten coal mines, which can replace similar imported products.
petroleum industry
In the 21st century, China's offshore oil development strategy proposes to focus on developing offshore and shallow oil fields. Therefore, in addition to using drilling oil pipes and vibrating oil pipes, the petroleum industry also requires the use of shallow oil pipelines. Shallow sea subsea oil pipelines have been produced domestically, but floating or semi floating oil pipelines and deep-sea subsea oil pipelines still rely on imports. With the implementation of China's offshore oil development strategy, the requirements for pipeline performance in offshore oil extraction will continue to increase.
Metallurgical industry
The equipment used in the production process of steel includes continuous casting equipment, which is divided into electric furnace converter and hot furnace converter. The requirement for rubber hoses is to have an armored surface for temperature insulation, cooling, and burning resistance. In addition to meeting the requirements of qualified pressure, oil pumps and pump stations must also meet the requirements of aging resistance.
Farmland water conservancy
The top document of the 12th Five Year Plan put forward a proposal for water conservancy and passed it, investing one trillion yuan in reform. Among them, in the process of water transportation, especially under negative pressure, the skeleton high-pressure rubber hose can show its advantages, long service life, and easy to carry.
