Pipe Stress Analysis
We offer specialized pipe stress analysis services to ensure the safety, reliability, and compliance of critical piping systems in industrial environments, using industry-standard software like CAESAR II to perform detailed analyses of piping subjected to various load cases, including sustained pressure, thermal expansion, seismic events, wind loads, and equipment vibrations.
Our expertise covers the complete spectrum of stress evaluations—identifying primary, secondary, and occasional stresses—ensuring compliance with international standards such as ASME B31.3, B31.1, B31.4, B31.8, and EN 13480, while verifying nozzle loads against allowable limits in API 610, API 617, and NEMA SM23, safeguarding sensitive equipment like pumps, compressors, and exchangers.
