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. It is likewise a tunnel that provides petroleum from underground to surface area. This item is a completion tool used after the drilling procedure and in the past well cementation.
4. The sizes of this pipes vary from 41/2″ to 20″. All pipes are produced strictly in accordance with API requirements.
N80 steel casing pipe is an essential tool used in oil well drilling (Other crucial tools consist of drill pipe, core barrel, casing, drill collar, little size steel tube utilized in drilling, and so on). The thread and coupling of this steel casing pipe are specially processed which have smooth surface area without any burr, tear or other problems.
API-5CT N80 casing pipe contains N80-1 and N80-Q types. Those 2 products are definitely consistent concerning the chemical structure and mechanical attributes, they are simply different in the heat treatment.
Throughout heat treatment, N80-1 steel is treated by stabilizing and tempering, while N80Q steel is treated by quenching and tempering. 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. With deeper downhole depth than J55 and K55 types, it can be requested the exploitation of middle-level oil and gas.
Due to the high ability of N80 product, those API-5CT casing pipes are broadly used in gas as well as coal bed methane extraction, and geothermal wells.
|Material:||L80, steel grade|
|Outer Diameter:||4 1/2″-20″, (114.3-508mm)|
|Thread Type:||Buttress thread casing, Long round thread casing, Short round thread casing|
|Function:||It is used to protect the tubing pipe.|
|Any product is subject oil quenching process above, the upper limit of the carbon content of L80 steel grade can be increased to 0.50%.|
API 5CT L80 petroleum casing pipe is the lifeline to preserve the operation of the oil well. The geological conditions are various in addition to the underground dynamics are complicated and disorderly. Pipes undergo be dictated under numerous forces, such as tensile force, pressure, flexing force, and torsional tension. Under such scenarios the need for remarkable quality for the casing pipe is must. In case of any failure, devastating results such as production disturbance or well termination are inescapable.
