The product is mainly used for injecting chemical agents into the wells. The upcoming 3/8" hydraulic control line is connected to the downhole chemical injection valve, and the cleaning chemicals are discharged from the ground through a certain concentration of 3/8" hydraulic control line and chemical injection valve from the ground into the underground pipeline, effectively clearing the oil pipe scaling, to ensure normal production of oil and gas fields. The present invention may also be used for ground pressure control valve and the other valve surface, and various connecting pipes of large oil drilling and production of large-scale equipment instrument control system.
Stainless steel coiled tubes is widely used in oil drilling, shipbuilding, aerospace and petrochemical oil refining equipment, spiral wound heat exchanger and chemical industry of cold treatment, gas transmission pipeline, fluid pipeline, steam insulation pipe cable, stainless steel heat tracing coiled tubes, high pressure fluid pipeline, stainless steel thermal insulation pipe cable, anticorrosive stainless steel pipe cable and umbilical cord protected by pvc sheath pipe and cable industries.
