API SPEC 5CT-1999 (casing and tubing specifications), released by the American Petroleum Institute (American Petreleum Instiute, referred to as "API") preparation and common around the world.
Including: casing from the ground surface into his drilling as the borehole wall lining the tube between the tube connected by coupling. The main material of steel grade J55, N80, P110, and resistance to hydrogen sulfide corrosion C90, T95 steel grade. Low-grade steel (J55, N80) welded steel pipe. Pipeline: from the ground surface into the pipe casing until the reservoir, through its tube coupling or the overall connection. Its role so pumping unit reservoir oil by pipeline transport to the ground. The main material for the J55, N80, P110, and resistance to hydrogen sulfide corrosion C90 T95 steel grade. Low-grade steel (J55, N80) welded steel pipe.
The oil casing oil drilling equipment, and its main equipment including drill pipe, core pipe and casing, drill collars and small-bore drilling with steel pipes. The domestic casing geological drilling steel hot-rolled or cold drawn made steel "geological" (DZ), casing steel grade DZ40, DZ55, DZ753 kinds.
Oil Casing Pipe,Material : H40, J55, K55, 280, N80, P110
1 Use
  Used in oil well drilling.
2 types
  Oil casing SY/T6194-96 "points short thread casing coupling and the long threaded sleeve coupling two.
Specifications and appearance quality.
  (1) the domestic casing SY/T6194-96 provisions, sleeve length not length, the range 8-13m. But not less than 6m casing can provide their number should not exceed 20%.
  (2) the inner and outer surfaces of the casing shall folding, hairline, separation, cracks, rolling, folding and scarring. These defects should be completely removed, clear depth of not more than 12.5% ​​of the nominal wall thickness.
  (3) the outer surface of the coupling shall have folded, hairline, separation, cracks, rolling off, scarring, and other defects.
  (4) casing and coupling threaded surfaces should be smooth, not allowed to have glitches, tear and impact strength and other defects closely connected enough to thread interrupt.
