That paragraph (T-434.1.7) is titled Block Curvature (Except for Piping). The provision to use a flat plate is NOT part of the Piping Calibration Block options! For Piping, you go to T-434.3 where you read that you must use a section of pipe of the same nominal size and schedule. Ed ----------- Start Original Message ----------- : For UT shear wave weld inspection of Circumferential joints on piping( OD less than 20"), is it necessary to have curved calibration blocks for DAC? Shall we use the the basic calibration block given in ASME ,T-434.2? ------------ End Original Message ------------ Follow Ups: Post a Followup: Name: E-Mail: Subject: Comments: ----------- Start Original Message ----------- : Varghese : Please go back to ASME Sec V Art 4 para 434.1.7 where you read about the Materials With Diameters Greater than 20 inch.
