PDI Alternative ASME Calibration Test Block (3 Set
Blocks)
PDI Alternative ASME blocks are
manufactured in accordance with the requirements of the Performance
Demonstration Initiative (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 an economical alternative to fabricating multiple curved calibration
blocks (pipe sections) in numerous diameters and wall thicknesses.
The blocks are normally supplied in sets of 3
individual blocks. Materials for each blocks are A516 Grade 70
Steel, 304/304L Stainless Steel and 316/316L Stainless Steel. Individual
blocks of anyone alloy are also available.
Overall block dimensions are 2.000" wide x
2.250" tall x 10.000" long. Block design consists of steps simulating
wall thicknesses measuring 0.500", 1.000", 1.500" and
2.000". Each step contains a .010" wide EDM notch, machined across
the width of the step at a depth of 10% of wall thickness. Scanning surfaces
and reflecting surfaces. Are machined to simulate pipe and plate surfaces of
250 Ra max finish. Each block is machine-engraved on one side with the Block
description, Serial No., Alloy and Heat No. All blocks are made from
ultrasonically inspected, heat number traceable materials.
Material: Steel 1018, Stainless
Steel 316, Stainless Steel 304.
