The conventional tubing supplied to oilfields with low aggressive environments: with pCO2 up to 0.3 atm and pH2S up to 0.005 atm often shows signs of pitting carbon dioxide corrosion after operation. To solve the problem, a new sparingly alloyed steel of 25KhGB was developed for K steel grade tubing with increased set of performance characteristics obtained after thermomechanical treatment.
