　　Oil Pipeline can be used in excavator, loader, rollover, hydraulic boost, hydraulic support, cement conveyor, agricultural irrigation hose, hydraulic tubing of construction machinery, undersea natural gas transportation, oil transportation and other fields.

　　I. Oil Pipeline For the Coal Industry

　　The main oil pipeline used in coal industry are hydraulic support rubber pipes. In recent years, the pressure oil pipeline requirement of some coal mine hydraulic support has been improved, and some steel wire braided hoses can not meet the performance requirements, requiring the use of steel wire wound oil pipeline. In addition, in order to prevent coal dust pollution and improve production safety during coal mining, the variety of oil pipeline used in coal mines has been increased, such as expansion oil pipeline of seam water seeker and sealing device oil pipeline, which are used for water injection and grouting in coal seams before fully mechanized mining in coal mines.

　　II. Oil Pipeline For the Petroleum Industry

　　In the 21st century, China's offshore oil development strategy puts forward the emphasis on offshore and shallow oil fields. Therefore, in addition to drilling and API 5L Grade B SCH 40 Oil Pipeline, the oil pipeline industry also requires the use of shallow oil pipelines. Shallow-sea oil pipelines have been produced in China, but floating or semi-floating oil pipelines and deep-sea oil pipelines still rely on imports. With the implementation of China's offshore oil development strategy, the requirements of offshore oil exploitation on the performance of oil pipelines will continue to improve.
