An evaluation of two popular ultrasonic thickness gau6es was made to future thickness testing of cast valve bodies at Br Nuclear Plant. and a Krautkramer D-meter.The comparison was made between a Nortec NDT-120 erry ings, pipe, and plate--with more emphasis on castin es, forg- readings were compared to actual micrometer readings and recorded Instrument . on attached sheet. Due to the following characteristics--acenracy, digital read to the Nortec NDT-120 CSS and most adaptable to o out, - or to facilitate these necdc. recommend purchase of the instrument as per t . eeds.

3.1 Direct Physical Measurement 3 1.1 This method may be used alone or in conjunction with the ultrasonic measurement method. 3.1.2 Direct physical measurement may be accomplished by the use of micro- meters, calipers, dial indicators or combinations of these measuring devices. 3.1.3 Accuracy of the measuring tools, devices or instruments shall be cali- brated against certified measurement standards which have known valid relationship to national standards. 3.2 Ultrasonic Measurement 3.2.1 Ultrasonic measurement shall be accomplished using the transmit-receive pulse echo methods employing equipment which has accuracy of measurement within 2 percent of the thickness being measured. 3.2.2 Equipment shall be calibrated on step wedge calibration blocks, on a calibration step thickness which is within .1 inch of the thickness being measured. We calibration block material shall be made from the "P" number (as identified in ASME Code Section IX, paragraph same Q-11.1 or QN-11.1) as the material being measured. For purposes of this specification, P numbers 1, 3, 4 and 5 are considered equivalent. When material availability permits, the calibration block. material shall be made from the same material type and product form as'the material being measured. . 9 w . . _ _ _ _ - - - , ._ _. _ _ _ . . - _ . _ , _ . . - - - _ _ _ , _ _ . . , _ _ , . -

M. l'. lt b Dates 6-4-73 ' )' , sheet: 2 cf 3 e . 3.2.3 Each test probe used shall be tested for accuracy on curved surfaces by calibrating on the step wedge calibration block and then checking for repeatability and accuracy on a curved surface which has a radius

equal to or less than that of the item to be measured and of the Lame thickness as that step calibrated against on the step wedge calibration block. (This test need only be made one time for each probe.) (b) 3.2.4 All details of the test equipment used, including test conditions, shall be recorded for each test performed. Glycerine shall be used as a couplant. (If it is necessary to use a couplant other than Glycerine to accommodate surface condition or other test variables, calibration in accordance with paragraph 3.2.2 shall be performed for each type of cog lant used.) . 3.2.5 Calibration of the equipment shall be performed at least once for each item or component and shan also be performed at least once for each thickness range specified in paragraph 3.2.2. 4.0 MEASUREMENT LOCATION AND RECORDS ' 4.1 At least two measurements shan be taken in each quadrant of items being measured. For pumps and valves, this requirement shan apply separately to the body, neck and weld or flange ends. For purposes of orientation, 00 shall be considered top dead center when looking into runs of the items or components, and for branches shall be the axis parallel to and in the , direction of low, with degree escalation clockwise. Prior to measure- a ment, temporary marking shall be placed on the item or component near the point of measurement indicating correct location. ._, 4.2 he mini == thickness for each quadrant shall be recorded and identified with the item, location and method of measurement. The results shall be recorded separately for each item on the appropriate form for the measurement method used. 4.3 me minimum van thickness at weld ends shall be measured immediately adjacent to the weld preparation. 4.4 For valves larger than 4 inch nominal pipe size, sufficient measurements shall be made to determine that the wall thickness dimension at weld ends does not reduce the body wall thickness to less than that required for minimum body wall thickness within a region closer to the outside sur- face of the neck than one mini == body van thickness, t , measured m along the run direction. 5.0 PERSONNEL QUALIFICATION - UT METHOD 5.1 Personnel performing utirasonic thickness measurements shall be quali- fied in accordance with ASNT-TC-1A. . .-- - ._. . . . _ - . - _ _ _ _ . _ - . _ . - - _ . __ -
