Common degradation process for industrial equipment in power and petrochemical industry is creep.The ultrasonic waves velocities and their ratio can provide feedback on stress-strain conditions generated by heat.Selection of potentially critically affected parts of pressure equipment can be theoretically accessed by their means.

Selection of such critical parts hp pavilion 15-eg1053cl or areas is done by comparison with reference benchmark value.Setting the standard reference value for conventional pressure purpose steel is crucial so it can be later used as a benchmark for selection stickers logos dallas cowboys of critical areas on equipment under operation.The article proposes a benchmark value to be utilized for P265GH pressure purpose steel and steels of similar grade.
