With the exploration and innovation of company people, gradually formed four major advantageous products: steel plate, steel pipe, stainless steel, special steel.
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.
N80. 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.
API color code: 1 red (N80-1), 1 red band + 1 bright green band (N80-Q) R95. Same yield strength range and tensile strength as grade T95, but without the requirement for SSC or hardness tests. Steel grade R95 therefore is a better-priced alternative to T95 in wells without the risk of sulfide stress cracking. Yield strength: 655-758 MPa (95-110 ksi),
N80 Casing Pipe Description. N80 steel casing pipe is a crucial tool utilized in oil well drilling (Other important tools consist of drill pipe, core barrel, casing, drill collar, little size steel tube used in drilling, etc.). This casing tube is made from steel of N80 grade. It is used for reinforcing the well wall.
Grade N80 Steel Casing Tube. As a specialized Grade N80 steel casing tube manufacturer and supplier in China, we also provide Grade J55 oilfield steel casing pipe, Grade P110 oil and gas tubing, and seamless steel boiler pipe, among others. As well as we are a specialized Grade N80 steel casing tube supplier across the world,best n80 pipe grade
API K55 is a general purpose pipe manufactured to API specification 5CT. Usually, this grade is most often used in casing applications. API N80 Type I is a lower cost alternative to standard Quench and Tempered API N80 (walls less than 0.500 inch). Charpy V-notch impact test absorbed energy results meet API SR16 and are lower than quenched-and-tempered N80.
Yaosheng is grade N80 steel casing tube supplier in China. This API 5CT grade N80 steel casing tube can be used for the oil well drilling process and can also support the wall of a well after the well completion, in order to ensure the normal operation of the whole oil well.
OCTG Tubing pipe goes inside the casing pipe because it is the pipe through which oil makes its way out. Tubing is the simplest part of OCTG and it is normally found in the segment of 30 ft (9 m), with threaded connection at both ends.
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.

Tubing grade guidelines. Thus L-80 grade steel has a minimum yield strength of 80,000 psi. In other words, it can support a stress of 80,000 psi with an elongation of less than 0.5%. The letter in conjunction with the number designates parameters such as the maximum yield strength and the minimum ultimate strength which for L-80 pipe are 95,000 psi.
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:
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.
Sour Service Steel Grades offered by U. S. Steel Tubular Products: API L80 is manufactured to API specification 5CT. This is a controlled yield strength material with a hardness testing requirement. L80 is often used in wells with sour (H2S) environments. API C90 is an API controlled yield strength grade generally for use in sour condensate best n80 pipe grade
Steel Grade (Casing Grades, Tubing Grades): J55, K55, N80-1, N80-Q, L80, P110. Type of Screw Thread: Non upset threaded end(NUE), External upset threaded end(EUE) Specialties: Threading; Heat treating; External upset; Drifting (Full-length, or just ends) Hydrostatic Testing; Full third-party inspection capabilities (EMI, SEA, and Weld Line)
Historically, N80 was introduced first. Some users preferred the quenched and tempered version. They didn't want to change the grade to require Q & T since the normalized product was popular (and a lower cost), so they introduced the L80 grade. Since most performance calculations are based on minimum yield, they can often be interchanged.
N80 is divided into N80-1 and N80Q, the same point of the two steel grades is the similar tensile properties and the difference between the two points is the delivery status and impact performance. N80-1 steel grade is in delivery state under normalizing state or when the final rolling temperature is greater than the critical temperature Ar3 best n80 pipe grade
Tubing steel grade. H40, J55, N80, L80, C90, T95, P110. N80 is divided into N80-1 and N80Q, the same point of the two steel grades is the similar tensile properties and the difference between the two points is the delivery status and impact performance.

J55, commonly used grade for most wells, has been the "standard" grade for tubing in most relatively shallow (< 9,000 ft) and low-pressure (< 4,000 psi) wells on land. N80, a relatively old grade with open chemical requirements, is susceptible to H2S and acceptable for sweet oil and gas wells in design conditions.
It is acceptable for sweet oil and gas wells when it meets design conditions. The quenched-and-tempered heat treatment is preferred. 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.
