Hello everyone.
I have a pressure vessel with an acceptable LTA and remaining life >10 years. It will be inspected in 5 years from now. I used 5 years to calculate the FCA. Should I use 10 years?
FCA definition says that is: "the corrosion allowance required for the future operational period...
Hello everyone.
I did a research in the design code trying to find a specific minimum distance between welds of re-inforcements. It seems that there is no restriction in how closer a nozzle can be put from another, just beware of the HAZ zone.
Does anyone know if there is a specific distance in...
Hello everyone,
I have a Rerated and Altered pressure vessel (i.e. MAWP increased and replacement of reinforcement pads in nozzles were done). The Rerating point of API 510 (8.2.1 (d)) says that the pressure test could be avoid if "the vessel integrity is confirmed by special nondestructive...
Hello. My case is a pressure vessel with no design data (0,70 by default). An ultrasonic inspection of welding were performed in order to increase this value. However, there were found laminations in shell, reaching the shell-head weld, so increasing vessel joint efficiency is not that easy...
