Ultrasonic Thickness Testing of Pipe Wall Thickness: Prior to measurements being taken, the subcontractor shall electrochemical etch each location a UT measurement is to be taken following the circumferential patterns shown in the attached datasheet. Each marking will be comprised of a circle roughly matching the diameter of the UT transducer to be used (e.g. 3/8-inch). See photo below as an example of the markings after etching is completed. The UT measurements shall be performed after the electrochemical etching has been completed to maximize repeatability of the measurements. If marking/writing is performed on the piping, it shall be done with a low chloride pen (e.g. Sharpie T.E.C. marker) to minimize potential pitting of the stainless steel piping. The attached datasheets shall be completed as part of this work scope and shall be submitted back to WRPS along with the UT inspection report from the NDE subcontractor. The subcontractor shall have a qualified ultrasonic testing technician (ASNT-TC-1A NDE Level II technician, minimum) perform as-built wall thicknesses at designated locations to support future measurements for monitoring erosion/corrosion within the tank farms waste transfer piping.

AW-02E Jumper F-G As-Built Pipe Wall Thickness Testing:
Locations of the measurements are specified in the attached datasheet. A total of six (6) measurement bands (measurements designated along the pipes circumferential perimeter) are to be established. Two (2) circumferential bands of measurements, spaced approximately 2-inches apart, are to be located upstream of the elbow at Connector F. Three (3) circumferential bands of measurements are to be located on the long radius elbow near Connector F, spaced approximately at a 30, 45, and 60-degree angle from the face of the elbow. One (1) circumferential band of measurement are to be located one (1)-pipe diameters (3.5-inches) downstream of the elbow.
AW-02A Jumper F-Z As-Built Wall Thickness Testing:
Locations of the measurements are specified in the attached datasheet. A total of five (5) measurement bands (measurements designated along the pipe circumferential perimeter) are to be established. Three (3) circumferential bands of measurements are to be located on the long radius elbow near Connector F, spaced approximately at a 30, 45, and 60 degree angle from the face of the elbow. One (1) circumferential band of measurements is to be located one (1) pipe diameter (2-3/8-inches) downstream of the elbow, followed by one (1) additional band of measurements 1 – 2-inches downstream of the previous location.
AW-B Valve Pit Jumper R1-A-(B) As-Built Wall Thickness Testing:
Locations of the measurements are specified in the attached datasheet. A total of four (4) measurement bands (measurements designated along the pipe circumferential perimeter) are to be established. One (1) circumferential band of measurements is to be located between Connector R1 and the first downstream long radius elbow. Three (3) circumferential bands of measurements are to be located on the long radius elbow near Connector R1, spaced approximately at a 30, 45, and 60-degree angle from the face of the elbow.
