PDI ALTERNATIVE ASME CALIBRATION BLOCKS

The new PDI Alternative ASME blocks meet the requirements of the Performance Demonstration Initiatice(PDI) Procedure No. PDI-UT-1, Rev. C, Fig. 4(Ferritic) and PDI-UT-2, Rev. C, Fig.4(Austenitic).

These cover the generic procedures for the ultrasonic examination of both ferritic and austenitic pipe welds. The blocks offer users an economical alternative to fabricating multiple curved cal blocks (pipe sections) in many diameters and wall thicknesses. The blocks are normally supplied in sets of 3 individual blocks; one in A516 Grade 70 Steel, one in Type 304/304L Stainless Steel, and one in Type 316/316L Stainless Steel. Individual blocks of any one alloy are also offered.

Block design consists of steps(wall thicknesses) measuring 0.500", 1.000", 1.500", and 2.000". Each step contains an EDM machined to a depth of 10% of wall x .010" wide x 2.0" long. Overall block size is 2.00" wide x 2.25" tall x 10.00" long. The scanning and reflecting surfaces are intentionally machined to simulate pipe and plate surfaces of 250 Ra maximum finish. Each block is permanently machine-engraved on one edge to include the block description, serial no., alloy, heat no., and FlawTech. The blocks are made from ultrasonically inspected, heat numbertraceable material supplied to FlawTech.

All Blocks Available In: CS 1018, AL 7075-T6, & SS 304 *all other materials available upon request*

EPRI CS-4774 Basic Calibration Block

Used for establishment of primary reference responses for UT examination of welds. Block contains three axial SDHs and two circ SDHs at 1.5" deep. Also contains one 1/8" diameter FBH at 0.5" deep and four notches at .031" deep x .063" wide x 1.5" long. In accordance with EPRI CS-4774, Fig. A-3 ASME Sec. XI Basic Piping Calibration Block Complete manufacture of the ASME Section XI Blocks including: supplying of pipe, machining of OD/ID(if needed), cladding (if needed), machining of all notches and side-drilled holes(SDH), machine engraving of all essential info including alloy, specification, diameter, wall thickness, and serial number. Blocks normally contain: one axial OD notch, one axial ID notch, one circumferential OD notch, one circ ID notch, three axial SDHs at 1/4, 1/2, and 3/4T, and three circ SDHs at 1/4, 1/2, and 3/4T. Can also be made from customer supplied material. We can upgrade your existing blocks to Sec. XI requirements by adding needed holes and notches.

All Blocks Available In: CS 1018, AL 7075-T6, & SS 304 *all other materials available upon request*
