gnee pipe team
API 5CT N80 casing is a high-strength, high-toughness petroleum casing that is widely used in oil field exploration and development around the world.
What is the specification of API N80 pipe?
Specification includes 1.9 inch(48.3mm), 2 7/8 inch(73.03mm), 2 3/8 inch(60.3mm), 3 1/2 inch(88.9mm), 4 1/2 inch(114.3mm), 4 inch(101.6mm) etc. N80 mechanical properties are higher than other types of API 5CT. The oilfield tubing can be classified as EUE type and NUE type.
What is the difference between N80 and L80 tubing?
The big difference is that N80 may be normalized, normalized and tempered, or quenched and tempered where L80 must be quench and tempered. Since it is quenched and tempered, L80 can be suitable for some sour environments, particularly if the hardness is kept below 23 HRC.
