Shock test stiffness is compared to load test of concrete piles. An ultrasonic acceptance standard will state which reflectors are acceptable or unacceptable based on the amplitude of the signal compared with a DAC curve or other ultrasonic specific acceptance criteria. being 2.5 m) and the length of the piles is 92 m. In comprehensive consideration of the various factors of the topography, hydrology, geology and construction time schedule in connection with the construction of the piles, it was determined that the piles should be constructed, using the scheme of the “hydraulic reclamation island platform+rotary boring machine”. The UT area should be clean of any surface matter, slag, splatter, etc., that could hinder inspection. 2.

Any discontinuity with a response greater than the response from a flat-bottom hole or equivalent notch (see footnote. of known diameter; discontinuities are evaluated with respect to this amplitude level. Cracks in tubes shall not be repaired and shall be considered cause for rejection. These trends are apparent from the extensive activity going on now in the United States and … 4.1 This practice is intended primarily for the examination of wrought metals, forged, rolled, machined parts or components to an ultrasonic class most typically specified in the purchase order or other contract document. Application of these criteria, however, requires certain specific inputs—primarily, an accurate measurement of discontinuity size. In a typical pulse/echo ultrasonic inspection system, a transducer in contact with the test specimen generates high frequency ultrasonic energy that travels through the test specimen in the form of waves. 1.1.2 The surface condition of the finished welds shall be suitable for the proper … Over ¼ in.
