API Thread Gauges for Rotary Drilling Equipment API 5B and API 7–1 are both standards set by the American Petroleum Institute (API) for thread gauges used in the oil and gas industry. API 5B specifies the dimensions, tolerances, and marking requirements for thread gauges used for the inspection of threaded connections in oilfield equipment such as casing, tubing, and drill pipe. These gauges ensure that the threads meet the required specifications for proper fit and sealing. API 7–1, on the other hand, is a standard that covers the requirements for rotary drilling equipment, including rotary subs, rotary tables, and drill stem components. It includes specifications for the threads used in these components, ensuring compatibility and proper connection during drilling operations. In summary, API 5B thread gauges are used for inspecting threaded connections in oilfield equipment, while API 7–1 covers the specifications for thread connections in rotary drilling equipment.
