Oil Casing and Tubing is a important equipment for oil drilling, its main equipment also include a core drill pipe, casing, pipe, drill collar and small caliber drilling pipe. Domestic casing is made of geological drilling steel after hot rolling and cold drawing , the number of steel expressing by geological" ( DZ ), commonly used in the grade of steel DZ40, DZ55, DZ753.

  Oil special pipe is mainly used for oil, gas well drilling and oil, gas transportation. It consists of petroleum drillpipe, Oil Casing and Tubing. Oil drill pipe is mainly used to connect the drill collar with the drill bit and transmits drilling power . Oil casing is mainly used for shaft support in the middle and completion of drilling , to ensure that the drilling process and the completion of the well after the normal operation. Pumping oil pipeline is main transported the oil and gas on bottom to the ground.

  We have adopted advanced production equipment and technologies to manufacture our seamless pipes and erwsteel pipes which can not only improve product quality, but also save raw materials. Our products have high strength, good toughness and resistance to corrosion.
