API Thread Gauges for Rotary Drilling Equipment

API Thread Gauges for Rotary Drilling
Equipment API 5B and API 71 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
71, 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 71
covers the specifications for thread connections
in rotary drilling equipment. To Know More
