N80,L80,P110 etc. The Casing pipe length range is R1,R2,R3, with threads of BTC, LTC, STC.

According to the strength of steel, casing pipe steel can be divided into different steel grades. Different

steel grade is used in oil well with different well depth. In corrosive environment also requires the casing

itself has corrosion resistance. In the complicated geologic condition place also asked the casing

having a anti-collapse performance.
