Failure Analysis and Remaining Life Estimation

In this section, based on the experiences of Razi Metallurgy Research Center in investigating the causes of failure and corrosion of industrial components with various applications, including the oil, gas, petrochemical, power plant, automotive, and cement industries, necessary studies are conducted on the failed components, and the causes and factors of component failure are precisely identified.

The equipment for failure analysis at this center includes advanced laboratory facilities, an electron microscope, qualitative and quantitative chemical analysis devices, a fully equipped metallurgical laboratory, and a complete mechanical laboratory. Utilizing these facilities by a team of trained engineers and staff with 40 years of experience in failure analysis and conducting over 300 complete failure analyses proves our credibility.

Razi Metallurgy Research Center's failure analysis capabilities allow providing solutions to prevent potential accidents. By combining experimental failure analysis techniques with quantitative methods such as fracture mechanics, fatigue analysis, and numerical modeling, technical solutions are effectively provided. The diverse expertise of the failure analysis team enables delivering the required information to clients in the shortest time and in the simplest form.

For lifespan assessment, the technical knowledge of dominant failure mechanisms on the component and the methodology for predicting the rate of failure propagation is utilized. To estimate the remaining life of components, a research tensile test is performed, and by extrapolating the results and matching them with BS and API standards, the remaining life is calculated.
