The conventional tubing supplied to oilfields with low aggressive environments: pCO 2 up 0.3 atm and pH S 0.005 often shows signs of pitting carbon dioxide corrosion after operation. To solve the problem, a new sparingly alloyed steel 25KhGB was developed for K grade increased set performance characteristics obtained thermomechanical treatment.

An elaborative study was carried out on the growth mechanism and properties of the passive film for a new kind of alloyed corrosion-resistant steel (CR steel). The passive film naturally formed in simulated concrete pore solutions (pH = 13.3). The corrosion resistance was evaluated by various methods including open circuit potential (OCP), linear polarization resistance (LPR) measurements, and ...

A novel sintered cutting stainless steel fiber felt with internal channels (SCSSFFC) composed of a stainless-steel fiber skeleton, three-dimensional interconnected porous structure and multiple circular microchannels is developed. SCSSFFC has a jagged and rough surface morphology and possesses a high specific surface area, which is approximately 2.4 times larger than that of the sintered bundle...
