Is it true that all Canadian provinces and most states in the U.S. require boilers and pressure vessels to be inspected during fabrication?

The statement that all Canadian provinces and most states in the U.S. require boilers and pressure vessels to be inspected during fabrication is indeed true. Boiler and pressure vessel safety is regulated through various codes and standards to ensure public safety and operational reliability. In Canada, this is governed by the Canadian Standards Association (CSA) and provincial regulations that mandate inspection at different stages of fabrication. Similarly, in the U.S., the American Society of Mechanical Engineers (ASME) sets standards, and many states adopt these standards into their regulations, which include inspection requirements during fabrication.

These inspections serve several key purposes: they help identify any potential design or material flaws early in the manufacturing process, ensure compliance with safety codes, and verify that appropriate quality control measures are being followed. Regular inspections can prevent failures that might lead to catastrophic accidents once the equipment is operational.

While there can be exceptions based on specific provincial or state laws, the broad requirement for inspection during fabrication is consistent with safety practices aimed at protecting both workers and the public. Such regulations highlight the importance placed on safety in the power engineering field, contributing to the overall reliability of boiler and pressure vessel installations across many jurisdictions.
