Ultrasonic Testing – It is a Non-Destructive method in which beams of high-frequency sound waves are sent into the materials for the detection of subsurface flaws in the material. By measuring this sound a skilled ultrasonic testing operator can identify location and size of imperfection, particularly that of wall thickness of the material.

The basic principle is that of "ECHO" reflection of ultrasound by voids. High frequency electrical signals are converted as mechanical vibrations in a Piezo-electric crystal. These vibrations form a wave front and are coupled to parts under inspection with suitable medium like oil, grease or water. These vibrations propagate through material in longitudinal, shear or surface modes and are reflected by any metal –air interfaces that are oriented approximately normal to incident sound wave. The reflected waves from such interfaces or flaws are directed back to the same transducer and are converted as electrical signals to the presented as a pip or vertical deflection in cathode ray tube screen (CRT) of an ultrasonic flaw detector Straight beam ultrasonic inspection, where sound beam enters vertically from the surface of inspection is specified to detect lamination in plates and internal discontinuities in forgings and castings. Angle beam inspection, where sound enters inside the material at predetermined angles to the surface, is specified for welds, rings and pipes to detect cracks and inclined flaws.

We are enlisted amongst the renowned service providers of Ultrasonic Testing Services. In these services, we use ultrasonic inspection for detecting imperfections or the changes done in materials. These can be utilized in varied thickness and are available at most affordable rates. Our entire services are as per the client's requirement and preference.


Magnetic particle inspection (MPI) is a non-destructive testing (NDT) process for detecting surface and slightly subsurface discontinuities in ferroelectric materials such as iron, nickel, cobalt, and some of their alloys. The process puts a magnetic field into the part. The piece can be magnetized by direct or indirect magnetization. Direct magnetization occurs when the electric current is passed through the test object and a magnetic field is formed in the material. Indirect magnetization occurs when no electric current is passed through the test object, but a magnetic field is applied from an outside source. The magnetic lines of force are perpendicular to the direction of the electric current which may be either alternating current (AC) or some form of direct current (DC) (rectified AC).The presence of a surface or subsurface discontinuity in the material allows the magnetic flux to leak, since air cannot support as much magnetic field per unit volume as metals. Ferrous iron particles are then applied to the part. The particles may be dry or in a wet suspension. If an area of flux leakage is present the particles will be attracted to this area. The particles will build up at the area of leakage and form what is known as an indication. The indication can then be evaluated to determine what it is, what may have caused it, and what action should be taken, if any.

Quality being the sole concern, we offer our clients an extensive range of Magnetic Particle Testing Services that are used to identify the surface and attached surfaces discontinuities in different metals including iron and steel. We utilize advanced techniques that functions on the principle of magnetic lines of force (flux). Our entire services are designed as per the quality standards and policies. These services are available using Electromagnetic yokes, etc.


Dye penetrant inspection (DPI), also called liquid penetrant inspection (LPI) or penetrant testing (PT), is a widely applied and low-cost inspection method used to locate surface-breaking defects in all non-porous materials (metals, plastics, or ceramics). The penetrant may be applied to all non-ferrous materials and ferrous materials; although for ferrous components magnetic-particle inspection is often used instead for its subsurface detection capability. LPI is used to detect casting, forging and welding surface defects such as hairline cracks, surface porosity, leaks in new products, and fatigue cracks on in-service components.

We are determined to provide reliable and efficient services so that these are used to locate surface-breaking defects in all non-porous material (metals, plastics, or ceramics). These services are executed as per the varied specifications of clients in order to gain their maximum satisfaction.
