L80

API 5CT L80 pipe is manufactured by American Petroleum Institute (API) authorized manufacturers. API 5CT L80 is a well casing steel pipe primarily used in petroleum industries. It helps to protect the well from collapse and other damage while drilling. It is also used in the production of casing and tubing for oil and gas wells. OCTG (oil country tubular goods) refers to a family of steel pipes that are used in the oil and gas industry, including API 5CT L80. These pipes are typically used to transport oil and gas from the wellhead to the surface, as well as to carry fluids within the well. Steel pipes like API 5CT L80 are essential components of the oil and gas industry, and they play a vital role in ensuring the safety and efficiency of operations.

  • THE APPLICATIONS OF API 5CT L80 CASING AND TUBING

    The well casing pipe is used to support the wellbore and protect it from collapsing. The petroleum industry typically uses API 5CT L80 tubing to extract oil and gas from wells. The L80 casing and tubing are known for their high yield strength and tensile strength. The L80 grade of steel is one of the most commonly used in the oil and gas industry. This type of steel is strong and durable, making it an ideal choice for well casing and tubing applications. Additionally, the L80 grade of steel has good weldability properties, making it easy to connect pieces of pipe.
