Understanding OCTG Piping in the Oil and Gas Industry
OCTG (Oil Country Tubular Goods) are specialized steel pipes essential for oil and gas operations, consisting of three main types: casing (structural wellbore lining), tubing (hydrocarbon flow conduit), and drill pipe (connects surface equipment to drill bit). These products must meet rigorous API standards and withstand extreme downhole conditions including high pressures, corrosive environments, and mechanical stresses to enable safe and efficient hydrocarbon extraction.
