1. Coal Mining Industry

Coal industry oil pipes are mainly hydraulic support hose. In recent years, the pressure requirements of some coal mine hydraulic supports have been increased, and some steel wire braided hose can not meet its performance requirements, requiring the use of steel wire wound hydraulic hose.

In addition, in order to prevent coal dust pollution in the process of coal mining and improve production safety, the variety of coal mine oil pipes has been increased, such as coal seam water exploration and sealing hole telescopic oil pipes

Water injection, grouting and other operations are carried out in coal seam before fully mechanized mining in coal mine and lower working face. It is reported that the domestic manufacturers have produced, and by more than a dozen domestic and international coal mine long-term application, can be a very stable replacement of similar imported brand products, and greatly reduce the cost of coal mining.

2. Oil drilling and production industry

In the 21st century, China’s offshore oil development strategy puts forward the key development of offshore and shallow sea oil, so the oil industry requires the use of shallow sea oil pipelines in addition to drilling pipelines and vibrating pipelines. 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 of offshore oil production on the performance of pipelines will continue to increase.
