NDE examinations must be scheduled at intervals that consider the Probability of the NDE method to identify the damage What is the transition temperature of a metal? The temp at which the material fracture code changes from ductile to brittle A primary goal of API 510 internal inspection is to Find damage that cannot be found by monitoring external CMLs When conducting a hydrostatic pressure test special attention should be given when testing low alloy steels especially 2 1/4 cr because T...

What is the description of damage of a brittle fracture? Sudden rapid fracture under stress (residual or applied) where material exhibits little or no evidence of ductility or plastic deformation What type of Steel are of primary concern with brittle fractures? Carbon and low alloy steels. 400 series SS are also susceptible What has a significant influence on toughness and resistance to brittle fractures? Steel cleanliness and grain size In most cases brittle fractures occur only at what t...
