About this publication

Overview The NB 23 NBIC 4‑Volume Set brings together all four parts of the National Board Inspection Code in one comprehensive package, covering the full lifecycle of boilers, pressure vessels, piping, and related pressure‑retaining items after initial construction. Developed and maintained by the National Board of Boiler and Pressure Vessel Inspectors, the code is updated on a two‑year cycle and published as a new edition in July of odd‑numbered years, including the 2025 edition. This set is an essential reference for jurisdictions, inspectors, owner‑users, manufacturers, repair organizations, and engineering firms responsible for maintaining pressure equipment safety and regulatory compliance. Contents of the 4 Volumes Part 1 – Installation Provides rules, requirements, and guidance to ensure all types of pressure‑retaining items are installed correctly and operate as intended. Topics include construction references, materials, design, supports, safety devices, operation, testing, and maintenance criteria for installation. Part 2 – Inspection Covers the procedures and documentation needed to perform in‑service inspections of boilers, pressure vessels, and other pressure‑retaining items. It addresses personnel safety, nondestructive examination, testing, common failure mechanisms, fitness‑for‑service, risk‑based assessments, and performance‑based inspection methods. Part 3 – Repairs and Alterations Defines acceptable methods for repairing and altering pressure‑retaining items, regardless of the original construction code. It includes rules for welding, examination, testing, heat treatment, and alternative methods when original construction requirements cannot be fully met, along with proven repair techniques. Part 4 – Pressure Relief Devices Provides detailed guidance for the installation, in‑service inspection, testing, and repair of pressure relief valves and other pressure relief devices used to protect pressure‑retaining items from overpressure. It covers device definitions, construction references, inspection requirements, repair procedures, performance testing, and documentation of pressure relief device activities. Key Features and Benefits Comprehensive post‑construction coverage across installation, inspection, repairs/alterations, and pressure relief devices in a single coordinated code set. Consensus‑based requirements developed by an expert NBIC Main Committee, supporting uniform administration and enforcement across jurisdictions. Clear organization with parts, sections, tables, charts, and figures that support practical use in the field and in engineering offices. Direct references to other codes and standards where additional detail is needed, helping users tie NBIC requirements into broader code compliance programs. Suitable for use by authorized inspectors, repair organizations, owner‑user programs, and regulatory bodies who must document compliance and maintain safe operation of pressure equipment. Typical Users and Applications This 4‑Volume Set is ideal for: Authorized inspection agencies and individual inspectors performing in‑service inspections and reviews. Repair and alteration organizations, including shops with National Board “R” or “VR” certificates, who must follow recognized methods and documentation practices. Owner‑users operating fleets of boilers, pressure vessels, and piping systems who require a structured program for integrity management. Consulting engineers and plant engineers who design, specify, or evaluate post‑construction activities on pressure equipment and pressure relief systems.
