Process systems don't forgive guesswork
Industrial work runs at pressures, temperatures, and consequences commercial buildings never see. Steam is the clearest example: a live steam line carries enormous energy, condensate management decides whether a system runs quietly for decades or destroys itself with water hammer, and trap selection is a craft in its own right. CraftIQ's industrial track drills that reasoning — steam and condensate behavior, compressed-air systems and the pressure drops that quietly tax every tool on the line, and the process-cooling and heat-exchanger logic that keeps production equipment alive. Demand-race puzzles make plant capacity concrete: watch which section runs out of air first and understand what undersized distribution actually costs. Process cooling rounds out the mechanical side: heat exchangers, cooling loops, and the flow logic that keeps production equipment inside its temperature window.
Classified areas and process piping
Two code frameworks give industrial work its edge. Piping splits by service: ASME B31.1 governs power piping — the boiler-adjacent, high-energy systems — while ASME B31.3 governs process piping, with a philosophy shaped by chemical service. Knowing which book a line falls under is itself an exam question and a jobsite question. On the electrical side, hazardous locations under the NEC change everything: Class and Division reasoning determines what equipment can legally live where flammable gases, vapors, or dusts may be present, and wiring methods that are routine elsewhere become violations. CraftIQ drills both through code-checks and spot-the-violation puzzles set in real plant scenarios, every answer cited to its standard. Knowing where a classified area ends is as valuable as knowing what belongs inside it.
Who the industrial track is for
This specialty serves UA fitters and welders heading into plants, mills, and process facilities, and IBEW electricians facing classified-area work — plus the maintenance techs who keep those facilities running and inherit every code decision the installers made. Journeyman-level fundamentals are assumed; the track adds the industrial layer on top. It is free for individual players, bilingual English/Spanish, and code-audited like the rest of CraftIQ. Industrial contractors can license it for crews, with per-topic dashboards that show who is ready for classified-area work before the plant orientation does — cheaper feedback than a failed inspection or a shutdown.

Frequently asked questions
What is the difference between ASME B31.1 and B31.3, and does CraftIQ cover both?
B31.1 is the power piping code — boiler and high-energy steam service — while B31.3 is the process piping code shaped by chemical and refinery work. Which code governs a given line is a real jobsite question, and CraftIQ covers both in its industrial piping puzzles.
Does CraftIQ cover hazardous-location (Class/Division) wiring?
Yes — classified-area reasoning under the NEC is a core industrial topic: what Class and Division describe, how classification changes acceptable equipment and wiring methods, and spot-the-violation puzzles where ordinary commercial practice is exactly what is wrong.
Is the industrial track useful for plant maintenance technicians?
Yes. It was built for construction trades, but maintenance inherits every one of these systems — steam traps, compressed-air distribution, heat exchangers, classified-area equipment. The reasoning drills translate directly to troubleshooting, and the code library doubles as a plain-language reference.
Does CraftIQ cover steam systems?
In depth for a training app — steam and condensate behavior, why condensate management makes or breaks a system, water hammer as a predictable failure rather than a mystery, and the reasoning behind distribution sizing. Puzzles cite the governing ASME piping codes throughout.
