Part 43

Part 43 is a set of federal regulations in the United States that governs the approval, qualification, and operation of drilling and production equipment used in oil and gas wells. It ensures that equipment such as blowout preventers, valves, and other safety devices meet safety and quality standards before being used in drilling operations. This regulation helps prevent accidents, control well pressure, and protect workers and the environment by establishing procedures for testing, inspecting, and maintaining this equipment throughout its service life.
