API 5B covers dimensions, tolerances, and marking for API threads and the gauges that control the acceptance criteria for the threads. It includes thread element gauges, instruments, and requirements for the inspection of threads for line pipe, casing and tubing (round threads), and buttress casing connections.

To change from inches to mm multiply by 25.4. The pictures below are typical API fittings and are only shown as examples. The theoretically correct distance for measuring pitch diameter is 5/8"/ (.635" to .620") from the shoulder of an external thread.
This specification covers dimensions, tolerances, and marking requirements for API threads and the gauges that control the acceptance criteria for the threads. Thread element gauges, instruments, and requirements for the inspection of threads for line pipe, round thread casing, round thread tubing, and buttress casing connections are included.
The API round thread is defined in two different lengths, one as a Short Round Thread (STC) and one as a Long Round Thread (LTC). The LTC thread is used for axial loads and especially when there are no high temperatures or extreme pressure in the borehole.
7 paź 2022 · The API connections include 8rd (pronounced “eight round”-implying eight threads per inch), 10rd, Buttress (BTC), and Extreme-Line (XL) designs. API Standards 5B and 5CT contain the geometric, performance, and gauging specifics for the available API connections and address tubing and casing sizes 1.050″ through 20″.
