13CR oil casing
Export 13CR oil casing, special buckle casing. Commonly used special buckle replacement buckles are VAM TOP, NEW VAM, chrome 13Cr tubing shorting / casing coupling, HYD buckle type, etc. With the continuous development of oil and gas fields in China. A large number of 13Cr steel grades (L80-13Cr) have appeared in deep wells, ultra-deep wells, high-pressure oil and gas wells, thermal recovery wells, directional wells, and corrosive media wells containing CO2 or H2S. Each production plant has established its own non-API steel grade. Take Kawasaki Steel as an example, 13Cr tubing short joint / 13Cr casing, its non-API 13Cr has 8 levels,
Among them, the last 4 steel grades are called super 13Cr. In the environment where CO2 and H2S coexist or the H2S partial pressure does not reach the critical value but Cl- is very high, 13Cr steel (including super 13Cr) cannot meet the requirements, and 22Cr duplex stainless steel (ASF2205) or super duplex stainless steel is required. 25Cr, even high Ni, Cr stainless steel and Ni-based alloys containing more than 20% Cr and more than 30% Ni. Forged (rolled) and cast heat-resistant stainless steel and nickel alloys used in the petroleum and petrochemical industries Type characteristics Application areas The above-mentioned steel grade pipes are expensive, and generally cannot be produced in low-yield gas fields. Therefore, in recent years, domestic and foreign countries are researching and developing economical CO2 corrosion-resistant oil well pipes containing Cr2-5%.
