Where are the ASME code markings usually found on a fire tube boiler?

The ASME code markings on a fire tube boiler are typically found on the right side near the front by the water column. This location is strategic for visibility and to ensure compliance with safety regulations. The code markings provide critical information regarding the boiler's design, construction, and safety standards, which are essential for maintenance and operation.

Locating the markings near the water column allows for easy access and inspection, ensuring that operators and maintenance personnel can readily verify that the boiler meets the required codes and standards for safe operation. This placement is important for both regulatory compliance and for the safety of personnel working with or around the boiler.
