English
API 5CT L80 tubing pipe is a medium-grade steel pipe used in the oil and gas industry, adhering to the API 5CT standard. It has a minimum yield strength of 552 MPa and a minimum tensile strength of 655 MPa.
This pipe is designed to provide structural support and transport fluids such as oil and gas from the reservoir to the surface. It is particularly suitable for wells with corrosive fluids, especially those containing hydrogen sulfide (H2S), due to its enhanced corrosion resistance.
The L80 grade is available in different types, such as Type 1, 3Cr, 9Cr, and 13Cr, with varying chromium content to meet specific corrosion resistance needs.
