13Cr-L80 casing and tubing for CO2 oil and gas wells
This product covers 13Cr-L80 casing and tubing under API 5CT. The existing excerpt positions the application for oil and gas wells with carbon dioxide environments. Published size ranges on this page include casing OD from 114.3 mm (4.5″) to 339.7 mm (13.38″) and tubing OD from 60.3 mm (2.38″) to 114.3 mm (4.5″).
Chemical composition limits already listed include C 0.150–0.220, Mn 0.250–1.000, Cr 12.000–14.000, Ni max 0.500, Cu max 0.250, P max 0.020, S max 0.010, and Si max 1.000 (other elements as shown on the current page). Mechanical properties published here include tensile strength 655 MPa min (95,000 psi min), yield strength 552 MPa min to 655 MPa max (80,000–95,000 psi), total elongation under load 0.500%, and hardness 23 Max HRC / 241 Max HBW. Keep these published values as the on-page baseline.
Confirm OD, wall thickness, thread, and heat-lot documentation against your tubular design before order. Share the well CO2 / corrosive-service basis so CNPS can align 13Cr-L80 supply to the program.
Key applications
- Oil and gas wells with carbon dioxide environments
- API 5CT 13Cr-L80 casing strings within the published OD range
