The basic calibration block is fabricated from a customer supplied 8” pipe section. Pipe section should be the same diameter, schedule, heat treatment and material type, as the material being examined.
Geometry:
Contains 4 notches: 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. Notches are made using EDM machining with 0.125" wide electrode ground to match the contour of the pipe segment.
* If you cannot provide a pipe section to make the pipe standard, e-mail us your diameter, schedule, heat treatment and material requirements and we will check availability with an alternate supplier. Pricing list on product page only valid when customer supplies pipe section.
