NDT - Ultrasonic testing (UT/UFD/ULT/UTT)
We DBV valve group co., ltd can do UT non-destructive test as customers require by the third party like TUV,BV,SGS,NATIONAL QUALITY SUPERVISION AND INSPECTION CENTER OF VALVE, etc .
Ultrasonic testing is another form of non destructive testing where a transducer applies ultrasonic pulse waves in the frequency range of 0.5 to 10MHz in the material and the time of flight of the ultrasonic waves is measured from the initiation time to the return of the reflection to the transducer.
Any change in acoustic impedance produces ultrasonic reflection or echo.
This property of the ultrasound is used to identify the material wall thickness and any internal discontinuities in material.
Ultrasonic testing is very sensitive test method for detection of embedded linear discontinuities. Ultrasonic testing is faster and economical as
compared to radiographic examination.
The common applications of ultrasonic testing are wall thickness measurement (UTT), corrosion mapping, lamination testing (ULT) , flaw (discontinuities) detection in the material e.g. welds, castings, forgings and other wrought products (UFD), density measurement of material, hardness measurement, etc.
Ultrasonic testing is commonly used test method in aerospace industry, shipping and offshore industry, fabrication industry and other general industry.
We perform ultrasonic tests in accordance with AS 2207, AS 2083,  AS 2574, AS 1065, AS 2452.3, AS 2824, AS 1101.3, AS 1929, ASME V Article 4, ASME V Article 5, ASME V Article 23,  ASTM E164, ASTM E114, ASTM A609, ASTM A388, ASTM A745, AS 1554 series, AS 3978, AS 3992, AS 2885.2,  AS 1665, AS 1710, ASTM 2375, EN 1714, EN 12680-3, BS EN 10160, ISO 10543, ISO 11496, ISO 4386.1, CECT, API and other similar national and international standards.
