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.
API 5CT seamless steel tubing. Peotroleum and natureal gas industies - Steel pipes for use as casing or tubing for wells. API 5CT is a standard on the oil casing by American Petroleum Institute, mainly for the oil pipe, tubing and casing.
API Tubing Grade & Specifications . Fluids Engineering Data. API Tubing Grade & Specifications . The following guidelines apply to the use of API tubing grades. H40: Although an API grade, H40 is generally not used in tubing sizes because the yield strength is relatively low and the cost saving over J55 is minimal.
General Purpose Steel Grades offered by U. S. Steel: API H40 is a general purpose pipe manufactured to API specification 5CT. API J55 is a general purpose pipe manufactured to API specification 5CT. Similar to K55 except the minimum tensile strength is lower. , best s355jr impact test this grade is most often used in casing applications. API N80 Type I is a lower , best s355jr impact test
1. The yield strength of N80-1/Q is 173 ~ 206 MPa higher than that of J55.. 2. The elongation of N80-1/Q is higher than that of J55 on the same sample area. 3. With the same specification, the same sample orientation, and the same minimum sample size, the absorption energy of J55 steel couplings, coupling blanks, coupling materials, coupling blanks, and accessory materials is lower than that , best s355jr impact test

1. The yield strength of N80-1/Q is 173-206Mpa higher than that of J55. 2. The elongation of N80-1/Q is higher than that of J55 on the same sample area. 3. The same specifications, the same sample orientation, the same minimum sample size, the absorption energy of J55 steel grade coupling, coupling blank, coupling material, coupling semi-finished product and accessory material is lower than , best s355jr impact test
General purpose pipe manufactured to API specification 5CT. Available in both standard Quench and Tempered API N80 and lower cost Normalized API N80 (walls less than 0.5"). 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 in Normalized N80 than Quench and Tempered
API Casing Steel Grades Colour Codes. , best s355jr impact test Common Application Casing (H40, J55, K55, M65, N80, R95) Due to their lower price compared to other steel grades, casing pipes of steel grades J55, K55, and N80 are a popular choice for wells without stringent anti-corrosion or strength requirements.
API 5CT N80 and L80 Oil Casing Heat treatment PSL1 requirements:N80 and L80 same way (both can be rolled-state delivery); PSL2 requirements: N80 and L80product should be normalized or normalized and tempered overall, if thick, should be normalized or normalized and tempered after thickened.
Tubing Grade: Guidelines applied to the selection/use of tubing grades: H40 An API grade, The Yield strength is relatively low and the cost saving over J55 is minimal. This is why H40 is generally not used in tubing sizes, Used only for non-critical, shallow wells,
API-5CT N80 oilfield casing pipe contains N80-1 and N80-Q types. Those two materials are absolutely consistent regarding the chemical composition and mechanical attributes, they are just various in the heat treatment. During heat treatment, N80-1 steel is treated by normalizing and tempering, while N80Q steel is treated by quenching and tempering.
Application of API 5CT piping and tubing: gas, water and oil transportation in both oil and natural gas. Packing of API 5CT piping and tubing: Bare, in bundles,crates, crate protection at the both sides of tubes or according to customers requirements.
Petroleum Tubing main steel grade includes J55, N80, C90, P110 and some others. for more details check below Casing And Tubing Tables, Casing Grade Table, & Casing Data Tables. API 5CT J55 Casing:

J55, K55 and N/L80 casing grades are basically the same carbon steel, and are as good (or as bad) at resisiting sewater corrosion as any other carbon steel. The lower strength grades (H40 J55 K55 etc) would be specified over N80 and L80 if stress corrosion cracking is an issue. In many areas, L80 is more readily available than lower grades.

For that reason, the collapsing strength and internal pressure strength of N80Q are greater than that of N80-1. When N80 casing is picked, n80-1 or N80Q ought to be clearly shown by the designer. As its mechanical properties are higher than J55 and K55 types, it might really well be made use of to certain a little bit more challenging developments.
The N80 grade is normally less expensive than L80 grades. L80A 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.
The most common materials for OCTG pipes are API H40, J55, K55, L80, N80, P110, and Q125 (casing and tubing pipes). These API grades feature increasing mechanical properties (tensile and yield strength). OCTG casing and tubing pipes are available in the following material grades:
