Seamless Steel Concrete

To understand the seamless steel pipe concrete pump injection solidity and quality of cement concrete and pipe wall, using ultrasonic pulse method of construction quality of the master's Concrete filled Steel Tube Perform nondestructive detection and identification.

Ultrasonic testing of seamless steel pipe in concrete work, seamless steel wall along the propagation, the ultrasonic signal to detect whether an impact is detected problems people are concerned, but also whether the ultrasonic pulse was detected by steel concrete quality is the key. As long as the steel inside the concrete is dense, and with the pipe wall concrete cement good, then use when worn detection, the received signal first wave ultrasonic longitudinal wave concrete along the pipe radial transmission, and the time around the pipe wall half the circumference of the spread of the more long, its first break in the first wave after wave superposition, therefore, the quality of ultrasonic testing of steel concrete is feasible and effective.

Ultrasonic acoustic path depends on the diameter of the inner detector seamless steel pipe concrete and two layers of steel by ultrasonic wall and made close contact with the transducer, a thickness relative to the diameter seamless steel pipe concrete is much smaller, although steel the total is greater than the speed of sound speed of sound concrete, but the impact on the "sound" when the impact detection and detection of reinforced concrete sound path perpendicular to the row of bars means quite generally negligible. In order to facilitate the calculation, it is desirable as the actual pipe diameter propagating ultrasonic detection distance.
