API 5CT J55 TUBING SIZES OD 2-7/8”-- 4-1/2” LENGTH R1, R2
API 5CT Casing Tubing OCTG J55 Yield strength: 379-552 MPa (55-80 Ksi), Minimum tensile strength: 517 MPa (75 Ksi) J55 color code: 1 bright green band
API 5CT Casing Tubing OCTG K55 Yield strength: 379-552 MPa (55-80 Ksi), K55 Minimum tensile strength: 665 MPa (95 Ksi) K55 API color code: 2 bright green bands
API 5CT Casing Tubing OCTG N80 (N80-1, N80-Q) Both N80-1 and N80-Q have the same yield strength and tensile strength, but N80-Q, which is quenched and tempered, shows higher resistance to internal pressure and collapsing. On the other hand, casing N80-1 is cheaper to produce and the first choice was a higher collapse resistance is not needed. N80 Yield strength: 552-758 MPa (55-80 Ksi), N80 Minimum tensile strength: 689 MPa (100 Ksi) N80 API color code: 1 red (N80-1), 1 red band + 1 bright green band (N80-Q)
PROPERTY OF API 5CT Casing Tubing OCTG P110 With the highest yield strengths among all API 5CT casing grades, P110 are ideally suited for high-pressure formations in deep wells.
However, as steel becomes more susceptible to sulfide stress cracking the higher the yield strength, both grades should not be used in H2S environments.
P110 Yield strength: 758-965 MPa (110-140 Ksi ) P110 Minimum tensile strength: 862 MPa (125 Ksi ) P110 API color code: 1 white band
L80 grades L80-9Cr and L80-13Cr are suitable for application in CO2 environments, mainly because of their higher chromium content. L80 (L80-1, L80-9Cr, L80-13Cr)
L80 Yield strength: 552-665 MPa (80-95 ksi), L80 Minimum tensile strength: 655 MPa (95 ksi) L80 API color code (bands): 1 red + 1 brown (L80), 1 red + 1 brown + 2 yellow (L80 9Cr), 1 red + 1 brown + 1 yellow (L80 13Cr)
