1. Coal Industry

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.

2. Petroleum industry

To develop offshore and shallow oil fields, therefore, the oil industry requires the use of shallow oil pipelines in addition to drilling 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.

3. Metallurgical industry

The equipment used in the production of steel includes continuous casting equipment, which is divided into electric furnace converter and hot furnace converter. The requirement for the hose is that it must be armored and used for temperature insulation, cooling and burning resistance. It is used in oil pumps and pumping stations. In addition to the requirement to meet the qualified pressure, the aging resistance must meet the requirements.

4. Farmland water conservancy

The use of farmland water conservancy, especially in the case of negative pressure in the water delivery process, the skeleton high pressure hose can show its own advantages, long service life and easy to carry.
