coal industry
Oil pipes used in coal industry mainly include hydraulic support hose. In recent years, the pressure request of some coal mine hydraulic supports has been improved, and a part of steel wire braided hose can not meet its performance request, so it is requested to use steel wire to wind the tubing instead. In addition, in order to avoid coal dust pollution and improve the safety of consumption during underground coal mining, the types of oil pipes used in coal mines have been increased, such as the expansion oil pipes of the coal seam water detection hole sealer, which are used to stop water injection, grouting and other operations on the coal seam before the comprehensive mining of the coal mine underground working face. It is reported that there are already manufacturers in China who have tried it out in more than ten coal mines and can replace similar imported products.
petroleum industry
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 requests the use of shallow oil pipelines in addition to drilling pipelines and vibrating pipelines. Shallow sea subsea oil pipelines have been consumed domestically, but floating or semi floating oil pipelines and deep sea subsea oil pipelines are still imported. With the implementation of China's offshore oil development strategy, the requirements of offshore oil exploitation for tubing performance will be improved from time to time.
