The N80 grade is normally less expensive than L80 grades. L80:A restricted yield-tubing grade that is available in Type 1, 9 Cr, or 13 Cr. Type 1 is less expensive than 9 Cr and 13 Cr but more subject to weight-loss corrosion. L80 Type 1 is used commonly in many oil and gas fields because of higher strength than J55. API Tubular Yield & Tensile StrengthNotes:A lower-cost alternative to standard Quench and Tempered API N80 (walls less than 0.500 inch). Inspection, testing and dimensions are in accordance with API 5CT for grade N80. Charpy v-notch impact test absorbed energy results meet API SR16 and are lower than Quench and Tempered N80. API C90 Minimum Yield Strength:90,000 psi
Mar 16, 2018 · N80-1 or N80Q should be clearly shown by the designer when N80 casing is selected.As its mechanical properties are higher than J55 and K55 types, it may very well be utilized to certain a little more challenging formations. With deeper downhole depth than J55 and K55 types, it can be applied for the exploitation of middle-level oil and gas. Carbon Continental AlloysCarbon. By definition, all steel is a mixture of iron and carbon. Steel to which no alloy elements have been added is called carbon steel.. Carbon steel is used where moderate strength is needed in a non-corrosive environment. When other elements (chromium, molybdenum, nickel, vanadium, etc.) are added intentionally, it becomes an
>>The casing couplings are applied in casing whose sizes are from 4-1/2 to 20inch. >> The steel grade of casing couplings are available with J55, N80, L80, P110 ect. >> Surface has highly polished coating with clearly color band identification. >> Material has excellent performance in hardness and anti-collapse (Charpy test). >> High machining accuracy, with strict internal control precision. Experimental Study on Corrosion of J55 Casing Steel and Nov 18, 2020 · At the same temperature and pressure, the CO 2 corrosion rates of J55 and N80 were measured. The minimum corrosion rates of J55 and N80 are 0.112 mm/a and 0.109 mm/a, respectively, and both of which are moderate corrosion (NACE SP0775-2005) [ 41 ]. The maximum corrosion rates are 2.137 mm/a and 1.434 mm/a, and both are severe corrosion [ 41 ].
