1. Amapharamitha ayisisekelo we-API Reg Threads

- Uhlobo lwentambo: Intambo ye-bustress (ntambo), ehambisana ne-API 5B standard.

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

- Iphimbo:

- 2 3/8 "Usayizi:Imicu engu-6 nge-inch ngayinye(≈4.24 mm).

- 3 1/2 "usayizi:Imicu engu-6 nge-inch ngayinye(okufanayo ne-2 3/8 ").

- Intambo angle: 60 ° (layisha i-flank angle 3 °, hlaba i-flank angle 10 °).

2. Ukucaciswa okuyisisekelo  

Ubukhulu bubalwa ngokususelwa kububanzi obungaphandle obungaphandle (od) kanye nokuphakama kwentambo okujwayelekile (amayunithi: amayintshi):

| Usayizi wentambo      |Ogatina od      |Ububanzi bezimpande    |Ububanzi be-Base     |Kuphawula  

| I-API 2 3/8 "Reg Pin| 2.375 ku (≈60.33 mm) |≈2.266 in(57.58 mm) |≈2.240 in(56.90 mm) | Intambo Height ≈0.054 ku (1.37 mm), i-TAPER 1:16

| I-API 3 1/2 "Reg Pin| 3.500 ku (≈88.90 mm) |≈3.391 In(86.13 mm) |≈3.365 in(85.47 MM) | Intambo ukuphakama okufana no-2 3/8 ", i-taper efanayo

- Ububanzi bezimpande: Ububanzi obuncane endaweni yentambo (ububanzi obuncane). Ifomula: I-Ominal Od - 2 × umucu ubude.

- Ububanzi be-Base: Ububanzi bereferensi ekuqaleni kwentambo ye-tapered, accounting for the taper umphumela (imvamisa kancane kunesilinganiso sobubanzi).

- Amanani wangempela angaphansi kokukhiqiza ngokubekezelela (e.g., ukuma, i-makeup torque); Ukuqinisekiswa kokugcina kumele kusebenzise ama-gauges we-API 5B Master.

3. Ukucatshangelwa kohlelo lokusebenza  

- I-Seating Mechanism: I-API Reg Ricks ithenge kuphela ekubandakanyeni kwe-Flank kanye nokuhlangana kwe-Complions ukubopha uphawu futhiUkuntuleka kwensimbi ezimele yensimbi-kuya-metal. Ngemithombo yegesi ephezulu kakhulu, ukuxhumana kwe-premium (e.g., Hyd PH6, BGT Series) kuyanconywa.

- Izicelo ezijwayelekile:

- Ukuxhumeka kwe-Drill String (E.G., I-Hammer Drill bit Shanks, Drill Pipe Tool Joights).

- I-Tungsten Carbide Drill Bits, i-CrossOver Subs (E.G., I-Double-Pine Subs).

- Izidingo Zokwenziwa: Ukunemba kwemishini ye-CNC enezindawo zentambo ze-Copper-Plated ukuze zinciphise ubungozi obunentambo.

- I-API 2 3/8 "Reg Pin: I-Root Ububanzi ≈2.266 in, Base Ububanzi ≈2.240 in.

- I-API 3 1/2 "Reg Pin: I-Root Ububanzi ≈3.391 in, Base Ububanzi ≈3.365 in.

Uma unentshisekelo kumathuluzi okumba, woza ukuxhumana ne-GLOBORX.
