API 5CT casing pipe

الوصف

API5CT Oil Casing Pipe is the important equipment in petroleum drilling including drill pipe, core barrel and casing pipe, drill collar as well as small diameter drilling with steel tube etc. Domestic steel casing pipe is made with geological drilling steel through hot rolling and cold-drawing, the steel grade is indicated by geological (DZ).
Steel casing tube is a kind of pipe to support the sidewall of oil and gas well to guarantee the drilling process and the whole oil well normally operate after drillings. According to different drilling depth and geological conditions, each well uses several layers casing tube. Different from the oil pipe and drilling pipe, steel casing pipe is the one-time consumption material without repeating using, so it adopts cement to fasten oil well. Therefore, the consumption of casing pipe is accounted for more than *0% of the total oil well pipe.
Based on the applications, steel casing pipe can be divided into catheter, surface casing, intermediate casing and oil-string casing.
API5CT Oil steel tube is mainly used in petroleum industries. Henan Union steel pipe for oil and gas includes drill pipe, tubing, casing, coupling stock, line pipe, and so on. Tubing is a pipe that transports crude and natural gas from the hydrocarbon zone to the pipe on the earth surface after drilling. It is mainly used in oil wells for extracting petroleum and natural gas. Casing is a type of steel tube used for supporting the wall of oil and gas well. This steel pipe is typically used to enclose and surround a carrier pipe installed in the center of this pipe. Coupling stock is mainly applicable in the manufacture of pipe couplings. Drill pipe is a kind of steel tube with screw thread in the pipe end. It is used for connecting ground rig equipment and drill grinding equipment at the bottom of drilling wells. Line pipe is a type of steel pipe that is manufactured from high strength carbon steel. This steel tube can be used to build pipelines that transport a variety of resources including natural gas, oil, petroleum and water in the petroleum and natural gas industry.
API5CT Casing Tube Grades:: H*0， J*5，K*5， N*0， L*0， C*0，T*5， P**0， Q**5 etc.
API5CT Casing Tube End Processing Forms:: flush end, short round thread, long round thread, buttress thread and special shackle.
