Does the license cover boiler external piping or boiler non-external piping?

The correct answer is that the license specifically covers boiler external piping. In the context of high-pressure piping systems, boiler external piping refers to the piping that connects the boiler to other systems and components outside of the boiler itself. This includes any piping that transports steam, water, or other fluids from the boiler to external equipment or processes, and it is crucial for ensuring the safe and efficient operation of a boiler system.

This designation is important because the regulations and standards governing high-pressure piping systems often treat external and internal piping differently. The training and licensing focus on the unique challenges and safety considerations involved with external piping, including the potential for external environmental factors and the need for proper insulation and heat tracing.

While there may be licenses that cover other types of piping, in this case, the specificity of the licensing makes it clear that the scope is limited to boiler external piping. Thus, understanding this distinction is key for those working in high-pressure piping applications.
