API 5CT STEEL PIPES CASING PIPES OCTG J55

Yield strength: 379-552 MPa (55-80 ksi),

API 5CT STEEL PIPES CASING PIPES OCTG J55

Minimum tensile strength: 517 MPa (75 ksi)

API 5CT STEEL PIPES CASING PIPES OCTG J55 color code: 1 bright green band

API 5CT STEEL PIPES CASING PIPES OCTG K55 Yield strength: 379-552 MPa (55-80 ksi),

API 5CT STEEL PIPES CASING PIPES OCTG K55 Minimum tensile strength: 665 MPa (95 ksi)

API 5CT STEEL PIPES CASING PIPES OCTG K55 API color code: 2 bright green bands

API 5CT STEEL PIPES CASING PIPES 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 a higher resistance to internal pressure and collapsing. 

On the other hand, casing N80-1 is cheaper to produce and the first choice were a higher collapse resistance in not needed. 

API 5CT STEEL PIPES CASING PIPES OCTG N80 Yield strength: 552-758 MPa (55-80 ksi),

API 5CT STEEL PIPES CASING PIPES OCTG N80 Minimum tensile strength: 689 MPa (100 ksi)

API 5CT STEEL PIPES CASING PIPES OCTG N80 API color code: 1 red (N80-1), 1 red band + 1 bright green band (N80-Q)

PROPERTY OF API 5CT STEEL PIPES CASING PIPES OCTG P110

With the highest yield strengths among all API 5CT casing grades, API 5CT STEEL PIPES CASING PIPES OCTG 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.

API 5CT STEEL PIPES CASING PIPES OCTG P110 Yield strength: 758-965 MPa (110-140 ksi)

API 5CT STEEL PIPES CASING PIPES OCTG P110 Minimum tensile strength: 862 MPa (125 ksi)

API 5CT STEEL PIPES CASING PIPES OCTG P110 API color code: 1 white band

API 5CT STEEL PIPES CASING PIPES OCTG 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)

API 5CT STEEL PIPES CASING PIPES OCTG L80 Yield strength: 552-665 MPa (80-95 ksi),

API 5CT STEEL PIPES CASING PIPES OCTG L80 Minimum tensile strength: 655 MPa (95 ksi)

API 5CT STEEL PIPES CASING PIPES OCTG 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)
