2 Νοε 2017 · In this article, we shall discuss API drill pipe specifications (specs), classification & drill pipe connection thread types & tables.
1, API Spec 5DP, ISO 10424-1 and ISO 11961, such as tool joints for drill pipe and HWDP, bits, or boxes that mate with bits. Unless otherwise specified, bevel diameter tolerances shall be ±0,4 mm (± 0.016 in).
1 Δεκ 2017 · 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.
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.
