OCTG, or oil country tubular goods, refers to steel pipes specifically designed for oil and gas extraction, commonly known as oil well pipes in China. These pipes are primarily seamless, although welded variants also constitute a significant portion. They are categorized into four main types: oil pipes, casing pipes, drill pipes, and pipeline pipes, with various grades based on their material properties. The API classification system divides oil well pipes into four groups, encompassing 11 steel grades and 19 specifications, with distinctions based on chemical composition, tensile properties, yield strength, and hardness.
These grades can be classified as low, medium, or high based on yield strength and other properties. In addition to API grades, non-API oil well pipes exist, developed for specific challenges like ultra-deep wells, high temperatures, and corrosive environments. Production companies must adapt the composition of metal elements or employ different processing techniques to ensure the steel pipes meet performance requirements for various conditions.
