NDT & INSPECTION SERVICES
Our laboratory is material testing laboratory we have provide facilities of NDT & inspection service. our laboratory is best high rating laboratory in all over India. Non-destructive testing (NDT) is a test and analysis technique that is used by industry to evaluate the properties of a substance, component, structure, or system without damaging the original core with special differences or welding defects and For dissatisfaction happens. In Non destructive testing (ndt) these following tests are use for ndt
In concrete -Ultrasonic Pulse Velocity, ReboundHammer Test
ULTRASONIC PULSE VELOCITY TEST
We offer the services for testing concrete where the velocity of ultrasonic pulses is measured and identification of cracks, voids, strength and elasticity is checked determining the areas which can provide the basis for recognizing the defects. The pulse velocity in a material depends on its density and its elastic properties which in turn are related to the quality and the compressive strength of the concrete.
In ultrasonic testing, very short ultrasonic pulse-waves with center frequencies ranging from 0.1-15 MHz and occasionally up to 50 MHz are launched into materials to detect internal flaws or to characterize materials. The testing is done through the methods such as Reflection and Attenuation.
In reflection mode, the transducer performs both the sending and the receiving of the pulsed waves as the "sound" is reflected back to the device. Reflected ultrasound comes from an interface, such as the back wall of the object or from an imperfection within the object. The diagnostic machine displays these results in the form of a signal with an amplitude representing the intensity of the reflection and the distance, representing the arrival time of the reflection.
In attenuation mode, a transmitter sends ultrasound through one surface, and a separate receiver detects the amount that has reached it on another surface after traveling through the medium. Imperfections or other conditions in the space between the transmitter and receiver reduce the amount of sound transmitted, thus revealing their presence. Using the couplant increases the efficiency of the process by reducing the losses in the ultrasonic wave energy due to separation between the surfaces.
Ultrasonic Testing has high penetrating power which enables to detect the deep flaws determining the size, shape, orientation and nature of the defects in the area and through its high sensitivity it allows to test very small flaws. It has greater accuracy than other nondestructive methods in determining the depth of internal flaws and the thickness of parts with parallel surfaces
REBOUND HAMMER TEST
Rebound hammer test is done to find out the compressive strength of concrete by using rebound hammer.The hammer measures the rebound of a spring-loaded mass impacting against the surface of the sample.
