API 5CT Cr13 L80 J55 N80 P110 oil casing steel tubing is made from carbon and alloy steel gradesthataresuitable for variousoilfieldoperations. The composition of the steel tubing is carefully controlled to ensure highstrength, toughness, and resistance to corrosion. Cr13, L80, J55, N80, and P110 are the different grades of steel used in API 5CT Oil Casing tubing, each with its own unique properties and applications.
Cr13 is a chromium-based alloy steel that offers excellent resistance to corrosion and high-temperature oxidation. It is commonly used in oil and gas wells where the presence of corrosive fluids and high temperatures can degrade the casing string. L80 is a medium-Carbon steel with a higher tensile strength than Cr13. It is suitable for wells with moderate to high pressures and temperatures.
J55 is a low-carbon steel that is widely used in shallow wells and low-pressure applications. It has goodweldability and is cost–effective, making it a popular choice for many oil and gas operators. N80 is a higher-strength steel with improved resistance to corrosion and higher collapse resistance. It is commonly used in deep wells and high-pressure environments.
