Mẫu chuẩn khuyết tật PH Tool ASME Sec V Basic Calibration Block
Used for establishment of primary reference responses for UT examination of welds.
Block contains three side-drilled holes at 1.5" deep minimum at 1/8" diameter. Hole locations through the thickness are ¼, ½, and ¾T. Also contains two EDM notches measuring 2%T deep x 1/4" max wide x 1.0" long min. In accordance with ASME Sec V Art. 4 Fig. T-434.2.1.
ASME Basic Calibration Blocks are intended to be representative of actual components, and therefore do not have the smooth scanning surfaces found on most general-purpose test blocks like the IIW or DSC. Instead, our Basic Calibration Blocks are media blasted on all surfaces to create a rough surface texture that is more characteristic of real-world inspection conditions.
- Dimensions: 1½" thick x 6¼" wide x 6" long
