RockySea petro : API 5CT L80

‌API 5CT L80 is a specification for the production of seamless steel tubes used in the oil and gas industry. It is a standard set by the American Petroleum Institute (API) that defines the material, dimensions, and testing requirements for these tubes. API 5CT L80 tubes are typically made from high-grade carbon steel and are designed to withstand the harsh environments of oil and gas exploration and production. They are manufactured in a variety of wall thicknesses and diameters to meet the specific needs of various applications. The tubes are seamless, meaning they are formed by drawing a heated metal billet through a die to create a continuous length of hollow metal tubing. This process ensures that there are no weak points or seams in the tube, which is important for the safe transportation and handling of oil and gas. API 5CT L80 tubes must meet stringent quality control standards during production, including dimensional accuracy, material composition, and mechanical properties. They are subject to rigorous testing to ensure they can withstand pressure, corrosion, and other harsh conditions they may encounter in the field. These tubes are used in a wide range of oil and gas applications, including drilling operations, well completion, pipeline transportation, and offshore production platforms. They provide a strong, reliable, and cost-effective solution for safely transporting oil and gas over long distances.

API 5CT L80 is commonly used in the oil and gas industry for constructing wellbore walls during drilling operations. It is also used in casing, production tubing, coupling stock, pup joints, and various downhole accessories.

Here are some other characteristics of API 5CT L80: 

• Minimum tensile strength of 655 Mpa
• Yield strength between 552 to 655mpa
• Higher than J55/K55, and similar with N80
• Equivalent to SAE 4140
