1. Basic parameter eAPI reg

- Thread mhando: Buttress Thread (reg tambo), inoenderana neAPI 5b chiyero.

- Toper: 1:16 (62.5 mm / m).

- Pitch:

- 2 3/8 "saizi:6 tambo pane inch(≈4.24 mm).

- 3 1/2 "saizi:6 tambo pane inch(zvakafanana ne2 3/8 ").

- Thread angle: 60 ° (Load Flank Angle 3 °, Stab Flank Akona 10 °).

2. Key Dimensional Dudziro  

Zvidimbu zvinoverengerwa zvichienderana neNominal Out Diameter (OD) uye Standard Speed Height (Units: Inches):

| Thread size      |Nominal od      |Midzi midzi    |Base diamita     |Kutaura  

| API 2 3/8 "Reg Pin| 2.375 in (×60.33 mm) |≈2.266 in(57.58 mm) |≈2.240 mukati(56.90 mm) | Thread kureba ≈0.054 mu (1.37 mm), Taper 1:16

| API 3 1/2 "Reg Pin| 3.500 in (≈88.90 mm) |≈3.391 In(86.13 mm) |≈3.365 In(85.47 MM) | Tambo kureba kufanana ne2 3/8 ", yakafanana taper

- Midzi midzi: Minimum Diamita pane iyo tambo midzi (diki diki). Fomula: Nominal od - 2 × Yekureba kureba.

- Base diamita.

- Chaizvoizvo tsika dzinoenderana neyekugadzira mishonga (i.e., yakangomira, makeup torque); Kupedzisira kuongororwa kunofanira kushandisa api 5b Master Gagus.

3. Kufunga kwekushandisa  

- Kuongorora Mechanism.kushaya chisimbiso chakazvimirira chesimbi-kune-yesimbi. Kune yakakwirira-yakadzvanywa gasi matsime, premium inobatanidza (i.e., hyd ph6, bgt series) inokurudzirwa.

- Chaizvoizvo Zvikumbiro:

- Drill tambo kubatana (i.e., nyundo yekukwevera zvishoma shanks, drill pombi tool majoini).

- Tungsten Carbide Drill Bits, Crossover Subl (i.e., kaviri-pini subs).

- Kugadzira zvinodiwa.

- API 2 3/8 "Reg Pin: Midzi midzi ≈2.266 in, base diameter ≈2.240 mukati.

- API 3 1/2 "Reg Pin: Midzi midzi ≈3.391 in, base diameter ≈3.365 mukati.

Kana iwe uchifarira zvishandiso zvekukwevera, uya uchionana nejasi.
