Testing Service

Radiography Testing Services This NDT method involves the use of penetrating X or gamma radiation to examine parts and products for imperfections. An X-ray machine or radioactive isotope is used as a source of radiation. Radiation is directed through a part and onto film. When the film is developed, a shadowgraph is obtained that shows the internal soundness of a part. Possible imperfections show up as density changes in the film.The beam of radiation must be directed to the middle of the section under examination and must be normal to the material surface at that point, except in special techniques where known defects are best revealed by a different alignment of the beam. The length of weld under examination for each exposure shall be such that the thickness of the material at the diagnostic extremities, measured in the direction of the incident beam, does not exceed the actual thickness at that point by more than 6%. The specimen to be inspected is placed between the source of radiation and the detecting device, usually the film in a light tight holder or cassette, and the radiation is allowed to penetrate the part for the required length of time to be adequately recorded.

Hydro Testing of Tanks & Bullets - A hydrostatic test is a way in which pressure vessels such as pipelines, plumbing, gas cylinders, boilers and fuel tanks can be tested for strength and leaks.

The pressure differential is dangerous, and fatal accidents have occurred in the history of pressure vessel development and operation. Consequently, pressure vessel design, manufacture, and operation are regulated by engineering authorities backed by legislation. For these reasons, the definition of a pressure vessel varies from country to country, but involves parameters such as maximum safe operating pressure and temperature, and are engineered with a safety factor, corrosion allowance, minimum design temperature (for brittle fracture), and involve nondestructive testing, such as ultrasonic testing,radiography, and pressure tests, usually involving water, also known as a hydrotest, but could be pneumatically tested involving air or another gas. The preferred test is hydrostatic testing because it's a much safer method of testing as it releases much less energy if fracture were to occur (water does not rapidly increase its volume while rapid depressurization occurs, unlike gases like air, i.e. gasses fail explosively).

Dye Penetrant Testing Services of revealing discontinuities that are open to the surfaces of solid and essentially nonporous materials. Liquid penetrant testing is probably the most widely used NDT method. The test object or material is coated with a visible or fluorescent dye solution. The excess dye is removed from the surface, and then a developer is applied. the developer acts like a blotter and draws penetrant out of imperfections which open to the surface. With visible dyes, the vivid color contrast between the penetrant and the developer makes the "bleedout' easy to see. With fluorescent dyes, and ultraviolet lamp is used to make the "bleedout" fluoresce brightly, thus allowing the imperfection to be seen readily.

Leak Test Services - Pipeline leak detection is used to determine if and in some cases where a leak has occurred in systems which contain liquids and gases. Methods of detection includehydrostatic testing, infrared, and laser technology after pipeline erection and leak detection during service.

Pipeline networks are the most economic and safest mode of transportation for oil, gases and other fluid products. As a means of long-distance transport, pipelines have to fulfill high demands of safety, reliability and efficiency. If properly maintained, pipelines can last indefinitely without leaks. Most significant leaks that do occur are caused by damage from nearby excavation equipment, therefore it is critical to call authorities prior to excavation to assure that there are no buried pipelines in the vicinity. If a pipeline is not properly maintained, it can begin to corrode slowly, particularly at construction joints, low points where moisture collects, or locations with imperfections in the pipe. However, these defects can be identified by inspection tools and corrected before they progress to a leak.

Magnetic Particle Testing Services is a non-destructive testing (NDT) process for detecting surface and slightly subsurface discontinuities in ferromagnetic materials such asiron, 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).
Magnetic particle testing 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.

Ultrasonic pulse velocity (UPV) test means to assist the transit time of ultrasonic pulses with 50–58 kHz, created by an electroacoustical transducer and passing from one surface of the element to the other. The transit time of ultrasonic pulses depends on the density and elastic properties of the material tested.

 Eddy Current Testing Services is based on the physics phenomenon of electromagnetic induction. In an eddy current probe, an alternating current flows through a wire coil and generates an oscillating magnetic field. If the probe and its magnetic field are brought close to a conductive material like a metal test piece, a circular flow of electrons known as an eddy current will begin to move through the metal like swirling water in a stream. That eddy current flowing through the metal will in turn generate its own magnetic field, which will interact with the coil and its field through mutual inductance. Changes in metal thickness or defects like near-surface cracking will interrupt or alter the amplitude and pattern of the eddy current and the resulting magnetic field. This in turn affects the movement of electrons in the coil by varying the electrical impedance of the coil. The eddy current instrument plots changes in the impedance amplitude and phase angle, which can be used by a trained operator to identify changes in the test piece.

Phased Array Ultrasonic Inspection Services generates an ultrasonic beam with the capability of setting beam parameters such as angle, focal distance and focal point size through computer controlled excitation. Furthermore, this beam can be multiplexed over a large array. These capabilities offer a series of possibilities. For instance, we can now quickly vary the angle of the beam to scan a part without moving the probe, and replace multiple transducers with a single element that produces various angle beams electronically. Inspecting a part with a variable angle beam also maximizes detection regardless of the defect orientation, while optimizing signal-to-noise ratio. Phased Array applications include, Angle beam inspection primarily used for weld inspection, Time of Flight Diffraction (TOFD) for detection and sizing of defects and the ability to more readily inspect complex geometries. For weld inspection Phased Array increases the probability of detection by offering the inspector additional tools to visualize the reflectors and their position within the weld. The ability to record the weld scans also allows us to utilize phased array for many projects that are constructed to ASME Code requirements

Ultrasonic Testing Services is one of the more common non-destructive testing methods performed on materials. This testing utilises high frequency mechanical energy, i.e. sound waves, to conduct examinations and measurements on a test area. Typically the UT inspection system consists of a transducer, pulser/receiver, and display unit. A pulser/receiver is an electronic device that can produce high voltage electrical pulses to the transducer. When driven by the pulser, the transducer generates high frequency ultrasonic sound energy into the material in the form of sound waves. When there are discontinuities such as inclusions, porosity, cracks, etc. in the sound path, part of the mechanical energy will be reflected from the discontinuities' (reflectors') surface. The reflected sound waves signal received by the transducer is then transformed back into an electrical signal and its intensity is shown on the display unit. The sound waves travel time can be directly related to the distance that the signal has travelled. From the signal, information about reflector location, size, orientation and other features can be determined.

Electrical Thermography Services is a science of using electronic optical devices to detect and measure radiation and correlating that to surface temperature.Thermal imagers can convert infrared radiation being emitted from the body into electric signals and thus present them visually. Infrared Thermography is the latest analysis tool for the detailed energy audit as the thermal cameras are powerful tool in viewing wall cavity insulation, ceiling insulation, moisture related problems. Several areas in electrical installations are not easily identified using conventional methods but these are able to locate with Thermal Imaging. Infrared Thermography is one solution for diagnosis used to determine the most effective plan of action to make the electrical installation more energy efficient.

In electrical engineering, transformer testing is a process of evaluating the performance of a transformer and measuring its working

Hardness Testing Services is a non-destructive mechanical testing method used to determine a material's resistance to deformation, indentation, or penetration. It is widely used for quality control, material verification, and wear resistance analysis across various industries.

Anultrasonic pulse velocity testis anondestructivetest to check the quality of concreteand natural rocks. In this test, the strength and quality of concrete or rock is assessed by measuring the velocity of anultrasonic pulsepassing through a concrete structure or natural rock formation. This test is conducted by passing a pulse of ultrasonicwavethrough concrete to be tested and measuring the time taken by pulse to get through the structure. Higher velocities indicate good quality and continuity of the material, while slower velocities may indicate concrete with many cracks or voids. Ultrasonic Pulse Velocity Method Pulse velocity=(Path length/Travel time)

Hammer impact test applied for fouling detection in pipelines The fouling detection in duct systems is a persistent problem and remains a relevant demand for the chemical, oil, food and pharmaceutical industries. The fouling is a deposition process of heavy organic and other dissolved solid materials in the transported fluids or suspensions onto inner wall surfaces in fluid transport systems. This work presents research results of hammer test for vibration analysis using non-invasive tests to fouling detection in pipelines. Data were taken from the vibration in presence of an inner pipe fouling layer using an accelerometer and a microphone for detection. With the analysis of the obtained results is possible to detect the fouling process, in the monitored pipelines, with and without load conditions, using a microphone and an accelerometer as sensors.

Rebound hammer test is done to find out the compressive strength of concrete by using rebound hammer as per IS: 13311 (Part 2) – 1992. The underlying principle of the rebound hammer test is
The rebound of an elastic mass depends on the hardness of the surface against which its mass strikes. When the plunger of the rebound hammer is pressed against the surface of the concrete, the pring-controlled mass rebounds and the extent of such a rebound depends upon the surface hardness of the concrete. The surface hardness and therefore the rebound is taken to be related to the compressive strength of the concrete. The rebound value is read from a graduated scale and is designated as the rebound number or rebound index. The compressive strength can be read directly from the graph provided on the body of the hammer.
