Análise comparativa do Código ASME e NR 13: o acompanhamento de inspeção e da elaboração de prontuário de uma caldeira mista

Abstract

This study addresses the inspection of boilers and the preparation of technical documentation from the perspective of the ASME Boiler and Pressure Vessel Code, Sections I and VIII, in comparison with the Brazilian Regulatory Standard NR-13. Considering the importance of steam boilers in industrial processes and the risks associated with their operation, the research aims to critically analyze the regulatory requirements related to structural integrity, operational safety, and technical documentation of such equipment. The methodology is based on a theoretical review of the applicable standards, a technical description of the main components of boilers, and the analysis of a real case study involving a mixed-fuel boiler used in an animal feed industry, including the base calculations for verifying the minimum thickness of shell and end plates, as well as the maximum allowable working pressure. The study also proposes a technical checklist to guide work routines to be followed during inspections, according to the criteria established by NR-13 and ASME, reinforcing the need for standardization and reliability in boiler operation.
