Optimization of pipe calibration block based on ASME V

Combined with the relevant technical requirements of ASME Varticle 4 for pipe calibration blocks, this paper optimized the pipe calibration block’s pattern, diameter and fabrication, block thickness selection, reflector selection, end edge type and other parameters, and the optimized designed calibration pipe block can reduce the number and weight of the calibration block, which was conducive to carrying and had a certain practical value.
