Products Description
API 5CT oil casing tube is designed specifically to support the wall of oil and gas wells, and prevent formation collapse. Its quality and performance directly determine the safety, stability, and service life of oil and has drilling. API 5CT standard provides detailed requirements for various steel grades to cope with complex working conditions, such as shallow wells, deep wells, ultra deep wells, and sulfur-containing gas fields, etc.
We supply API 5CT oil casing tubes of multiple dimensions to meet clients' different application needs. API 5CT oil casing tubes are made by seamless process, the dimension range is within 4-1/2" to 20" (114.3mm to 508mm). We can provide fixed length processing services according to project requirements.
Steel Grades of Oil Casing Tube
The API 5CT standard specifies multiple steel grades, which are adjusted through chemical composition optimization and heat treatment processes to adapt to different well depths, pressures, and medium environments. Among them, J55, K55, N80, L80, and P110 are the most widely used models. The key performance and applicable scenarios of each steel grade are as follows.

J55/K55 |
379MPa / ≥517MPa (J55),≥655MPa (K55) |
Shallow wells with depth ＜3000m, low-pressure formations, non-corrosive environments; surface/intermediate casing for onshore conventional oil and gas wells |
|
N80 (N801/N80-Q) |
552MPa / ≥689MPa
|
Medium-deep wells with depth 3000-5000m, non-acidic working conditions |
|
L80 |
552MPa / Strength ratio adapted to corrosive working conditions |
H₂S/CO₂-containing acidic environments |
|
P110 |
758MPa / ≥862MPa |
Deep/ultra-deep wells with depth 5000-7000m and high-pressure formations |
|
C110 |
758-828MPa / ≥793MPa |
Ultra-deep wells with depth ＞7000m, high-temperature and high-pressure sour gas fields, subsea oil and gas wells |
