casing and tubing coupling specifications: "' 1.315" '- 4-1/2 grade of steel is commonly used: J55, K55, N80-1, N80-Q, L80, P110, Q125, 13CR-80, 13Cr-110, Super 13Cr, etc.

Threaded fastener type: NUE, EUE, SC, LTC, BTC. Surface treatment: surface using phosphate or black finish, painted again. According to the strength of the steel itself casing can be divided into different steel grade, different well conditions, hole depth, the grade of steel are also different. In the corrosive environment, the casing itself is also required to have corrosion resistance. In the place of complex geological conditions, it is also required that the oil casing has the property of anti-crushing.
