below. Alternatively, eddy-current methods in accordance with NB-2554, Section 7II, ASME Code, may be used provided the material has uniform magnetic properties and the product is limited to sizes and thicknesses for which meaningful examination results can be obtained by eddy-current methods. b. Tubular products used for Class 1 vessel nozzles should be examined by the ultrasonic method in accordance with NB-2552 or the radiographic method in accordance with NB-2553 over the entire volume +i material and by the magnetic particle methodL accordance with NB-2555 or the liquid penetrant method in !.-rnrint-A w,,ith NB-55 oi'n 1 external surfaces and all accessible internal surfaces. c. Wrought seamless fittings (including flanges and fittings machined from forgings and bars) should be examined by the ultrasonic method in accordance with NB-2552 or the radiographic method in accordance with NB-2553 over the entire volume of the material for which meaningful examination results can be obtained. Fittings or sections of fittings for which meaningful results cannot be obtained by these methods because of irregular geometry or size should be examined by the magnetic particle method in accordance with NB-2555 or the liquid penetrant method in accordance with NB-2556 on all external surfaces and all accessible internal surfaces. d. Welded tubular products (with filler metal added) should be examined in accordance with NB-2560, Section IIl of the ASME Code. When the option for ultrasonic examination of finished welded pipe is invoked as permitted by NB-2560, the examination should also meet the requirements of ASTM E-213, "Standard Method for Ultrasonic Examination of Metal Pipe and Tubing," and paragraphs C.2. and C.3. below. 3 Piping of 2 inch nominal pipe size or less which meet: design requirements of NB-3673, Section III, ASME cod, exempted from the examination requirements. 1.66-2 2. Ultrasonic Examination a. The procedure for ultrasonic examination should provide a
