Which code does this activity belong in?
This code covers establishments that manufacture power boilers and heat exchangers, which are heavy gauge pressure vessels designed to generate steam or transfer thermal energy. The boundary with Metal Tank Manufacturing is that power boilers and heat exchangers are specialized equipment engineered for high-pressure or high-temperature applications, whereas metal tanks are general-purpose storage vessels. Light gauge metal containers formed by other establishments are fundamentally different in construction method and intended use, involving thinner materials and simpler forming processes rather than the heavy gauge fabrication required for boiler and heat exchanger production.
