ASME Code Structure

▣ Code & Standard Characteristics

  • Developed, integrated, or modified as needed.
  • Comprise both mandatory and optional requirements.
  • Involve a wide range of stakeholders with numerous producing entities.
  • ASME regulations are legally adopted and enforced by individual states in the U.S.
  • Focused primarily on Mechanical Engineering but play a leading role as codes and standards across all technical fields.
  • Classified into four categories:
    • Professional Societies
    • Trade Associations
    • Test and Certification Organizations
    • Standards Developing Organizations

▣ Overview

  • ASME Code : Established to ensure public welfare and system safety for users.
  • Code Case: Issued swiftly by the committee when there is a need for interpretation of existing codes or to address topics not covered in the current code.
  • ASME: The American Society of Mechanical Engineers is responsible for certification and standardization in the mechanical field.

 

▣ ASME Code Structure I

  • Contains sections with common applications.
  • Classified by function: Sections for manufacturing and maintenance.
  • Includes regulations for the design, fabrication, installation, testing, and inspection of boilers, pressure vessels, and other components.

 

▣ ASME Code Section II

  • Contains information on various materials.
  • Includes tables and charts according to regulatory requirements.

 

ASME Code Section III

  • Items exempted in ASME III (NCA-1130b): valve operators, controllers, position indicators, pump impellers, instruments.

 

ASME Code Grades

▣ ASME Qualification Certification System

  • Establishes procedures to certify companies that can engage in design, fabrication, and construction according to ASME Boiler and Pressure Vessel Code requirements.
  • Differentiates items with specific stamps from those without.
  • Applicable items:
    • General Industry: All pressure vessels above 5 psig, including heat exchangers, columns, drums, etc.
    • Nuclear Industry: Reactor pressure vessels, tank containment vessels, pumps, valves, core supports, structures, piping, etc.

 

▣ ASME Authorized Certification System

  • Ensures pressure-containing equipment related to safety is designed, fabricated, installed, and operated according to design requirements and relevant standards (ASME Code).
  • Authorized Inspection Agencies (AIA)
  • Authorized Nuclear In-Service Inspector (ANIS)
  • Authorized Nuclear Inspector (ANI)
