non-pipe weld ASME Calibration Block - NDT-KITS
ASME calibration block (non pipe)
Standard: ASME BPVC-V-2015
The size and shape of ASME non-pipe weld test block are shown in
the chart below, when inspected
For inspection on materials with surface diameter greater than
500mm, test blocks with the same curvature as the workpiece or
standard test blocks with a diameter equal to or less than 500mm
can be used
During the upper inspection, the curve test block, namely the tube
seam test block, should be used.
1. The distance between each slot and either end of the test block
or other slots is not less than T or 25mm, if larger.
2. The minimum length L of the test block shall be 200mm or 8T, if
larger.
3. When the inner diameter is equal to or less than 100mm, the
minimum radian is 270°. When the inner diameter is greater than
100mm, the minimum arc length is 200mm or 3T, and the larger is
taken
4. The depth of each tank is 11% T≥h≥ 8% T, width ≤6mm, length
≥225mm
