What is NBIC?

NBBI NB 23 or NBIC as its commonly known, is a standard developed by the National Board of Boiler and Pressure Vessel Inspectors (NBBI) to regulate the design, fabrication, installation, and inspection of boilers and pressure vessels. It is made up of 4 parts and was originally published as a guide for chief inspectors in 1946.

The standard emphasizes the importance of considering the potential risks associated with the use of NBIC in boilers and pressure vessels, and outlines the necessary safety measures to mitigate these risks. It also encourages the use of NBIC to improve the efficiency and performance of boilers and pressure vessels, while maintaining their safety.

What is the purpose of NBIC?

The purpose of the NBIC is to maintain the integrity of pressure-retaining items after fabrication by providing common rules for: Installation, Inspection, Repairs and Alternations and Pressure Relief Devices. and has since become an internationally-recognized standard. It provides guidelines and requirements for the safe use of NBIC in the design and manufacture of boilers and pressure vessels, ensuring their reliable operation and preventing accidents.

NBIC is regularly updated to ensure that it remains current with the latest technological advancements in NBIC and related fields. Compliance with this standard is mandatory for all manufacturers and users of boilers and pressure vessels in the United States, who must demonstrate that their products meet the requirements of NB 23 before they can be used.
