Product Description
ST TECH Sonic logging pipes ( Sounding Testing Pipes / Sonic Steel Pipes/ Tubes)
is the necessary and essential part of modern bridge construction.Using a sonic log pipe we can test a pile's quality. It will enter the internal body of the pile just as a channel when the cast-in-place pile has an ultrasonic test. It's an important part of cast-in-place pile ultrasonic test system.

Applications
Drilled shafts are prepared for integrity testing by CSL during their construction by installation of at least three sonic tubes. These tubes are usually attached to the reinforcement cage along the full length of the shafts. After concrete has been poured, the tubes are filled with water. In CSL, a transmitter emits an ultrasonic signal in one tube and the signal is sensed some time later by the receiver in another sonic tube. Poor concrete between the sonic tubes will delay or disrupt the signal. The engineer lowers the probes to the bottom of the shaft and moves the transmitter and receiver upward, until the entire shaft length is scanned. The engineer repeats the test for each pair of tubes. The engineer interprets data in the field and later reprocesses it in the office.
