ASME Basic Cal. Block for Pipe
(The basic calibration block fabricated for customer supplied section of pipe of the same diameter, schedule, heat treatment and material type as the material being examined. Contains 4 nothces: longitudinal, and circumferential on both OD and ID at a depth of 10% of the wall thickness. Notches are 1/4" max. wide x 1" min. long. Block is fabricated in accordance with ASME SEC. V article 4 Fig. 434.3.)
ASME Basic Calibration Block
(Used for establishment of primary reference responses for UT examination of welds. Block contains three side-drilled holes at 38mm deep minimum at 2.5mm diameter. Hole locations through the thickness are 1/4, 1/2 and 3/4 T. Also contains 2 EDM notches measuring 2% T deep * 6.4mm max wide * 25 long min. In accordance with ASME Sec V T-434.2.1)
