NOTES: Per API 5C1:
Sect. 5.2.4
Joints should be made up approximately 2 turns beyond the hand-tight position.
For basic power-tight make-up, the face of the coupling or box advances to the vanish point. (API 5B Fig. 8)
Make-up target should be governed by position rather than torque. (API 5C1 Table 3)

Sect. 5.3.1
1. These values apply to tubing with Zinc-plated or Phosphate-coated couplings, utilizing API Mod Thread Compound.
    Thread compounds other than API Mod, may require different torque values, due to different frictional properties. (API 5C1 Sect. 4.3.4)
2. Connections with Tin-plated couplings can be made up at 80% of the listed torque values.
3. Round thread connections with PTFE seal rings should be made up at 70% of the listed torque value.
