Nondestructive testing -acoustic pulse
1.What is called sound pulse?
A pulse generated by sound wave
2.Introduce principles of sound pulse testing
When sound wave spread with pipe,if the pipe exists opening, hole bulging, sunken,crack, internal corrosion and deposition,then it will have reflected wave return back to launching terminal,due to sound wave has fixed spread speed,by computer dealing,then get accurate position that pipe occur abnormal situation
3.Introducing Applicable range of sound pulse testing
Sound pulse fast speed leak detector is suitable for fast speed leakage testing of nonferrous metal 、black metal and nonmetal pipe,such as condenser tube,boiler tube:heat exchanger tube in chemical plant;on-service leakage testing on central air conditioner tube in tower
4.What are features of Sound pulse testing
①On-service tube high speed leakage testing ,can up to 500-1000sets tubes
②Tube material is not limited,ferromagnetic or non ferromagnetic or non metal tube
③Straight tube ,elbow,winding pipe
④quickly discover penetrability flaw on tubes
⑤Real time record testing waveform,convenient to be compared when next inspection
5.What technical characteristics does Sound pulse testing instrument have?
Gain range
Observing length
Changeable Background signal restrain
Changeable probe excitation intensity and pulse width
