The Impact-Echo Test Speed To Inspect The PCCP

WE NEED TO APPLY THE IMPACT-ECHO TESTING ON PRE-STESSED CYLINDER CONCRETE PIPES FOR
(THE GREAT MAN-MADE RIVER PROJECT IN LIBYA).
COULD I ASK YOU ABOUT THE SPEED OF THIS TEST TO INSPECT MORE THAN 4000 TO 55OOO
PIPES TO DETERMINE THE HOLLOW SOUNDING IN THE CEMENT MORTAR GROUTING (I MEAN THE
CEMENT MORTAR DELAMINATION IN THE GROUTING).
AND HOW TO DETERMINE THAT BY THIS ROLE IN THE PCCP?.
Note: PCCP mean pre-stressed cylinder concrete pipe.

Re: The Impact-Echo Test Speed To Inspect The PCCP
That depends on how extensive you want to investigate for each pipe. If you are looking for any delamination around the tendons in concrete, then, you can just do two lines (one each at easily accessible height) along the pipe lines. For each line, you can do it at 200mm interval. It can be done very fast (10 to 15 second for each impact). Interpretation of the resutls is relatively easy. You can try CTG from Olson Engineering or Ultrasonic Pulse Echo (Dry Point Contact) from ACS.

Regards,

Tony from Australia

nresolved asset integrity problem in the industry. Current methods for measuring wall thickness with liftoff, without removing insulation, all have severe limitations. Eddyfi introduces Lyft — a reinvented, high-performance pulsed eddy current (PEC) solution. The patent- pending system features a state-of-the-art portable instrument, real- time C-scan imaging, fast data acquisition with grid-mapping and dynamic scanning modes, and flexibility with long cables. It can also scan through thick metal and insulation, as well as aluminum, stainless steel, and galvanized steel weather jackets. Who else but Eddyfi to reinvent an eddy current technique and redefine CUI programs. Got Lyft?
