I got my PSI-PCI training two years ago, and I dunno if I'd do it again. The class was interesting, and the knowledge that I gained was useful...but ye gods...the itself class was expensive, so breaking even on that will take more than a few years. Plus, the cost of the tools and specialized viz gear is f***ing
obscene.
- Crows-foot wrench sets that will fit tank valves are at least $100. Ain't no getting around that expense.
- The torque wrench for the crows-foot heads can run beyond $100 if you get a high-quality one.
- Internal-inspection lights run $150-280 unless you get the cheap-ass piece-of-s**t rope light sold on Amazon for $80.
- The periscope-thingy for thread inspection sells for $185, and that's just for 3/4" necks. Got a 3/8 neck? That'll run you an extra $65.
- And then let's not mention the other doodads like picks, angled mirrors, pit gauges, official PSI-PCI stickers, and the like. Estimate $20 per unit on those.
The first year I did my own inspections, I got lucky when another inspector loaned me his toolkit. That was free, but I shelled out for the crows-foot heads and bought a cheapie Harbor Freight torque wrench for about $20 (the owner of my LDS would undoubtedly deride it, and loudly).
This year, the other inspector moved out of town, and I was facing a $400 expense for inspection gear. I got smart, though, and piecemeal-ordered the minimum necessary doodads and built my own inspection lights (both visual-spectrum and UV) for about $40.
Even so, I'm still in the hole financially on tank inspections, and I will be for a few years to come.
Oh, and don't get me started on all the necessary equipment for oxygen-cleaning that I just plain don't have, such as a tumbler and a rack for hanging the tanks upside-down and a nitrox-clean tank full of O2-clean air and a whip with a nozzle for air-drying the cleaned tanks' insides...
