API 5CT L80 Casing Tubing is a API 5CT Oil Casing Pipe & mainly used for oil well drilling. We manufacture API 5CT L80 Casing Tubing in accordance with the SY/T6194-96 standard, it is available as short thread type and long thread type supplied with their couplings. According to American Petroleum Institute Standard API SPEC 5CT1988 1st edition, the steel grade of API 5CT oil casing pipe can be divided into ten types, including H-40, J-55, K-55, N-80, C-75, L-80, C-90, C-95, P-110 and Q-125. We supply the casing pipe & API 5CT L80 Casing Tubing accompanied with thread and coupling, or we offer our product in accordance with the following forms for option. If you are interested in API 5CT L80 Casing Tubing, we will supply you with the best price based on the highest quality.

What is API 5CT L80 Casing Tubing?

OCTG: Oil country tubular goods is the classification used for a variety of downhole products API 5CT L80 Casing Tubing serves to transport both crude oil and natural gas from oil and gas layer to the surface pipeline after drilling is completed. It is able to bear the pressure produced by the exploitation process. After the outer surface is coated with a protective layer, the tubing is marked in accordance with the API 5CT standard and strapped with metal belt. Our oilfield tubing & API 5CT L80 Casing Tubing can be widely applicable to petroleum, construction, shipbuilding, smelting, aviation, electric power, food, paper, chemical industry, medical equipment, boilers, heat exchangers, metallurgy and so on. This oilfield tubing can be classified as NUE type and EUE type. You can find here Casing Dimensions & Casing Wall Thickness. Specifications include 1.9in(48.3mm), 2 3/8in(60.3mm), 2 7/8in(73.03mm), 3 1/2in(88.9mm), 4in(101.6mm), 4 1/2in(114.3mm) etc. The depth of our product for descending the well is basically identical to that of oil casing pipe. Both mechanical property and sealing performance of this tubing are also required to correspond with the oil casing pipe. 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 L80 Casing:
L80 Casing is placed downhole to provide structural integrity to the wellbore and must withstand external-collapse pressure from rock formations and internal-yield pressure from fluid and gas. It must also hold its own deadweight and withstand the torque and transaxial pressure placed on it while running downhole.
API 5CT L80 Tubing:
L80 Tubing is placed within the casing. It is used to transport oil and gas from the source rock to the wellhead.

a. Code is used for ordering reference.
b. The nominal weight of threaded and coupled casing (column 2) is shown for reference only.
c. Martensitic chromium steel (L80 9Cr and 13Cr) differs from carbon steel in density. The shown weight of martensitic chromium steel is not an exact value. The mass correction factor 0.989 can be used.
d. C90, T95 and Q125 steel grade casing should be supplied according to specification, weight and wall thickness listed in the above table or order.

API 5CT L80 Casing Tubing Features

  • API 5CT L80 Casing Tubing is offered with a free length range from 8 to 13m on basis of the SY/T6194-96 norm. However, it is also available no less than 6m length and its quantity should be no more than 20%
  • Any deformation such as crease, hairline, separation, crack or scab is not acceptable on both inner and outer surfaces of the product. All these defects should be completely removed, and the removed depth must not exceed 12.5% of nominal wall thickness.
  • Deformations which mentioned above are not allowed to appear on the outer surface of API 5CT L80 Casing Tubing coupling.
  • The surface of thread of coupling and API 5CT L80 Casing Tubing should be smooth without any burr, tear or other defects that may have a negative impact on the strength and close connection.
API 5CT L80 Casing Tubing Packaging
In compliance with the regulation of SY/T6194-96, the domestic API 5CT L80 Casing Tubing should be strapped with steel wire or belt. The protection ring should be screwed on the exposed part of the thread of each casing pipe and its coupling to well protect the thread.
