The system is suitable for the automatic detection of various internal and external defects of steel pipes. The principle of ultrasonic flaw detection is that after the ultrasonic wave is coupled into the steel pipe through water, the incident propagation will cause ultrasonic reflection when there is a defect in the pipe. The ultrasonic instrument will alarm the ultrasonic reflected signal after realizing the signal to realize the automatic detection of the defect; Transmission ultrasonic equipment is currently the advanced detection equipment in China.Wireless Transmission Ultrasonic Pipe Testing Equipment IntroductionRotating probe configuration1. Probe configuration on the spindle section 1A total of 3 probe adjustment frames are placed on section 1 at 120Β°apart. Each of the adjustment frames is equipped with a 2-channel combined ultrasonic line focusing longitudinal probe to detect longitudinal defects of the steel tube in a clockwise direction.Detection of defects: Vertical and vertical defects in the steel pipe are detected in a clockwise direction.Center frequency: 5.0MHzΒ±10%Coupling method: water immersion method Quantity: 3 sets of probes, each consisting of 2 wafers. These 3 sets of probes are evenly distributed in the circumferential direction of the workpiece, spaced 120Β° apart, on the same section. A total of 6 channels of water immersion probes.2.Probe configuration on the main shaft section2A total 3 probe adjustment frames are placed on section2, separated by120Β°, and a 2-channel combined ultrasonic line focusing longitudinal probe is arranged on each adjustment frame to detect longitudinal defects of the steel pipe counterclockwise.Detection of defects: counter-clockwise detection of longitudinal defects inside and outside the steel pipe.http://www.bkneddy.com/ultrasonic-testing-equipment/wireless-transmission-pipe-flaw-detector.html
War is a thing of the past. Science has created superpowered clones who established world peace under a single, central government. Today, the clones participate in the Games. It's the biggest, most popular form of entertainment on the planet. Not only do fans love it, but the clones, called Contestants, love it as well. The brightest star among them is Contestant Melvin, known as the Master of the Earth and Skies. Contestant Melvin possesses movie star good looks, the strongest, flashiest powers in the Games, and an undefeated Tournament title. He's exactly where he wants to be.But when he finds himself suddenly "freed" by a radical clones' rights group, none of that matters. Alone, far from his beloved Games and fans, nothing he's trained for can help him cope. Why can't these people understand that freedom isn't something he wants? Why do they keep telling him that everything he believes is a lie? And why do they continue to insist that he's human?
