Acoustic pipe inspection can thickness much

Acoustic detection in Jiangsu is in accordance with the measured points to calculate the average was 20cm, a measuring point,25 yuan /, acoustic detection according to the tree, each district are not the same, and acoustic pipe tree is different, the price is also different frequency probe, is this your. Capable of detecting cast iron, but nodular cast iron of high grade so sorry, detection are not allowed. For example, more than QT1200. Your probe frequency is 5MHz, belongs to the low frequency probe, iron because the ultrasonic belongs to high frequency electromagnetic wave, the material has strong penetrating power ultrasonic waves in steel the velocity of sound in the why not? As long as the wall thickness greater than 6mm are capable of using ultrasonic to inspection. Ultrasonic detection30mm

Such as:20mm, high pressure pipe weld by ultrasonic flaw detection of weld quality and pipe material quality? That probe is best? Results: sorry, error. 20mm high-pressure tubing refers to: the diameter of 20mm. There are all these models are easily manipulated, about you to Baidu search" Shenzhen Taili apparatus", to find their own. You ask the ultrasonic detection apparatus has many kinds, present at the start of the easy manipulation of digital ultrasonic

I admitted to the graduate student, then tell you. Velocity of propagation of the ultrasonic wave is strong, the steel plates in the dissemination of time can be measured. Then the velocity multiplied by the time naturally derived interval - plate thickness

?2, vertical wave probe testing, the largest find defects in steel ultrasonic longitudinal wave velocity is 5900m/s, if the frequency is 2MHz, the wavelength is ( ). A,59mmD, ~~1~5CADBB6first synchronizer beg an expert: zero second: at the sound speed of third: check the measured face watch battery because what tests do not Guangzhou East-ru electronics company DR6ultrasonic thickness gauge ) adjusted velocity, can be directly measured.
