Is an ultrasound examination required within the reinforcement area of the embedded fitting?
Thread Content
I see on the drawings for high-voltage equipment that ultrasonic testing is to be carried out within a range twice the size of the opening at the mounting fitting. Where does this statement come from? Seek a solution
GB/T150.3P296: “There shall be no delamination in the steel plate section at the openings in the shell.”
The requirement for ultrasonic inspection within the reinforcement area of the embedded fitting is determined in accordance with relevant standards and specifications. This requirement may stem from the relevant technical standards or industry regulations of ** or the region, and the specific requirements may vary. To ensure the quality and safety of socketed fittings, ultrasonic testing can be used to evaluate internal defects, damages, or corrosion in the fittings. This allows problems to be detected and fixed in a timely manner, ensuring reliability in use. It should be noted that specific requirements must refer to relevant standards and specification documents to ensure accuracy. Different industries or fields may have varying requirements and standards; therefore, it is recommended that you consult relevant professionals or review relevant documents to obtain accurate answers. .
