Automation Tier Fit — Manual, Semi-Auto or Dual-Pump?
The right tier follows your throughput and pipe mix, not the biggest torque number on the page. Answer three questions and the tool maps you to a WL configuration — including when the cheaper tier is the correct call.
1. Coupling throughput on a working day
Low / irregular — mixed jobs
Steady runs of one size
High volume, continuous line
2. Pipe you buck most
Tubing and small casing (≤7″)
Intermediate casing (7″–13⅜″)
Large OD / conductor (>13⅜″)
3. How torque consistency is judged
Operator judgement is accepted
Consistency across a run matters
Every coupling needs a traceable record
Every WL tier carries the same never-stick grip and ZKN torque recorder — the record does not change when volume does. This tool maps workflow to tier; the OD and torque band still decide the model.
