Eddy Current Testing Calibration/Reference Standard

Eddy Current Testing Calibration/Reference Standard Eddy current testing is one of several non-destructive testing methods that use the electromagnetism principle for flaw detection in conductive materials. A specially designed coil energized with an alternating-current is placed in proximity to the test surface, generating a changing magnetic field that interacts with the test-part and produces eddy currents in the vicinity. Variations in the changing phases and magnitude of these eddy currents are then monitored through the use of a receiver-coil or by measuring changes to the alternate current flowing in the primary excitation-coil. The electrical conductivity variations, the magnetic permeability of the test-part, or the presence of any discontinuities, will cause a change in the eddy current and a corresponding change in phases and amplitude of the measured current. The changes are shown on a screen and are interpreted to identify defects. NDE FLAW TECHNOLOGIES PVT. LTD. are the manufacturer of standard blocks for Eddy Current Testing (ECT) according to the standards and codes.

Ultrasonic Testing Calibration/Reference Standard

Ultrasonic Testing Calibration/Reference Standard Ultrasonic testing (UT) comprises a range of non-destructive testing (NDT) techniques that send ultrasonic waves through an object or material. These high frequency sound waves are transmitted into materials to characterize the material or for flaw detecting. Most UT inspection applications use short pulse waves with frequencies ranging from 0.1-15 MHz, although frequencies up to 50 MHz can be used. One common application for this test method is ultrasonic thickness measurement, which is used to ascertain the thickness of an object such as when assessing pipework corrosion. Ultrasonic inspection uses a piezoelectric transducer connected to a flaw detector, which in its most basic form is a pulser-receiver and oscilloscope display. The transducer is passed over the object being inspected, which is typically coupled to the test object by gel, oil or water. This couplant is required to efficiently transmit the sound energy from the transducer into the part, however this couplant is not required when performing tests with non-contact techniques such as electromagnetic acoustic transducer (EMAT) or by laser excitation. According to Ultrasonic Testing (UT) principle NDE FLAW TECHNOLOGIES PVT. LTD. well export of making artificial flaws over subsurface in the test specimen also we are a manufacturer of calibration block according to the standards.

Magnetic Particle Testing Calibration/Reference Standard

Magnetic Particle Testing Calibration/Reference Standard This method is used for the detection of surface and near-surface flaws in ferromagnetic materials and is primarily used for crack detection. The specimen is magnetized either locally or overall, and if the material is sound the magnetic flux is predominantly inside the material. If, however, there is a surface-breaking flaw, the magnetic field is distorted, causing local magnetic flux leakage around the flaw. This leakage flux is displayed by covering the surface with very fine iron particles applied either dry or suspended in a liquid. The particles accumulate at the regions of flux leakage, producing a build-up which can be seen visually even when the crack opening is very narrow. Thus, a crack is indicated as a line of iron powder particles on the surface. The method is applicable to all metals which can be strongly magnetized – ferritic steels and irons, but not generally austenitic steels. The method of magnetization must produce a magnetic field with lines of force at a large angle to the expected direction of the cracks to be detected, so that it is usual to apply the magnetization more than once in different directions, for example in two directions mutually at right-angles, but methods of swinging the field direction during magnetization are available. According to MPI/MPT principle NDE FLAW TECHNOLOGIES PVT. LTD. well export of making artificial flaws in both surface and near surface in the test specimen also we are a manufacturer of calibration block according to the standards.

PAUT and TOFD Calibration/Reference Standard

PAUT and TOFD Calibration/Reference Standard Phased Array Ultrasonic Testing (PAUT), also known as phased array UT, is an advanced non-destructive inspection technique that uses a set of ultrasonic testing (UT) probes made up of numerous small elements. Each of these is pulsed individually with computer-calculated timing to create the phased aspect of the process, while the array refers to the multiple elements that make up a PAUT system. The beam from a phased array probe can be focused and electronically swept across an inspection piece without moving the probe itself. This differs from single element probes (also known as monolithic probes). These more conventional probes need to be physically moved or turned to cover larger areas, which is not required for PAUT. Phased array ultrasonic testing is based on the principles of wave physics, which also have applications in areas including optics and electromagnetic antennae. In time-of-flight diffraction (ToFD) systems, a pair of ultrasonic probes is used, sitting on opposite sides of a weld-joint or area of interest. A transmitter probe emits an ultrasonic pulse which is picked up by the receiver probe on the opposite side. In an undamaged part, the signals picked up by the receiver probe are from two waves: one that travels along the surface (lateral wave) and one that reflects off the far wall (back-wall reflection). When a discontinuity such as a crack is present, there is a diffraction of the ultrasonic sound wave from the top and bottom tips of the crack. Using the measured time of flight of the pulse, the depth of the crack tips can be calculated automatically by trigonometry application. This method is even more reliable than traditional radiographic, pulse echo manual UT and automated UT weld testing methods. ToFD offers great accuracy for measuring the critical through-wall size of crack-like-defects. The accuracy of greater than ±1mm can be obtained in a wide range of material thickness from which pressurised components are constructed. ToFD was initially developed as a method of accurate monitoring and sizing of through-wall height of in-service discontinuities in the nuclear industry. It has now been independently validated as one of the most effective techniques for locating and sizing discontinuities in ferritic welds. NDE FLAW TECHNOLOGIES PVT. LTD. are the manufacturer of standard blocks for Phased Array Ultrasonic Testing (PAUT) and Time of Flight Diffraction (ToFD).

Eddy Current Tube Calibration/Reference Standard

Eddy current testing of tubes is an effective way of assessing the condition and lifespan of tubes, particularly in the power generation, petrochemical, chemical, fertilizer and air conditioning industries. The technique is applied to detect corrosion, pitting, cracks, erosion and other changes to both the tube’s interior and exterior surfaces. It is a high-speed inspection method and one of the major advantages is that it can be performed through paint and coatings. The technique is only suitable for non-ferrous material such as stainless steel, copper and titanium. We also perform remote field and magnetic biased eddy current testing on carbon tubing. Eddy current testing uses electromagnetic induction to identify defects in tubing. A probe is inserted into the tube and pushed through the entire length of the tube. Eddy currents are generated by the electromagnetic coils in the probe and monitored simultaneously by measuring probe electrical impedance. The information revealed by the probe will detail the tube defects. The scanning data will be recorded by the software and kept us as a backup for future reference. A benefit of eddy current testing is that detection of defects is instant, and can be reported immediately to site or operation managers. Standard calibration tubes are manufactured by NDE FLAW TECHNOLOGIES PVT. LTD. with artificial flaw for calibrating the equipment.
