Thought tube rolling was a lazy shortcut until a 30 year hand at the Gary job walked me through it
I figured rolling tubes by hand gave a better seat than the expander, but after watching him pull and re-roll 6 tubes on a boiler feedwater heater with zero leaks at hydro, I switched. Anybody else running a torque-controlled roller, and what psi are you setting it at for 3/4 inch tubes?
