Radiographic testing can detect internal discontinuities such as voids, porosity, inclusions and cracks in piping & structural weldments , pipeline weldments , castings, valves & tubes in a wide range of materials, sizes and shapes. The interpretation of radiographic film of welds requires knowledge of not only welding and welding discontinuities, but also the exercise of good judgment as to whether the discontinuities are actually defects. Radiography technicians have extensive experience in film interpretation at both asnt level ii, asnt level iii benefits at a view: inspection of a wide variety of material types with varying density ability to inspect assembled components minimum surface preparation required sensitivity to changes in thickness corrosion voids cracks and material density changes the ability to detect both surface and subsurface defects and the ability to provide a permanent record of the inspection. Metus ndt services provide complete radiographic services for field applications. The trained certified inspector is able to read and grade the films and then determine if parts are acceptable or rejectable.

An ultrasound transducer connected to a ultrasonic machine is put in contact with the object that is being inspected. The end results are the pulse waves that are transmitted through the product. When measured, these can determine imperfections and thicknesses. They can even measure the size of the imperfections or inclusions in a product. Ultrasonic thickness gauge measurement (utg) are made using pulse-echo technique. This technique determines thickness or reveals corrosion discontinuities/ loss of wall thickness near the surface or deep within components or structures. It offers the advantage of examining components without removal or disassembly. Our personnel are trained in ultrasonic techniques and are certified to ut level I & ii as per american society for non destructive testing (asnt). They can interpret results on site and give a quick response so that the product can be compared to the given standard and appropriate measures can be taken. Main uses of ultrasonic testing: used to locate surface and subsurface defects in many materials like metals. Finding internal weld imperfection thickness measurements. Depth of penetration for flaw detection or measurement is superior to other methods. One side access is sufficient. Provides distance information. Minimum part preparation is required.

Hardness is the property of a material that enables it to resist plastic deformation, usually by penetration. However, the term hardness may also refer to resistance to bending, scratching, abrasion or cutting. The usual method to achieve a hardness value is to measure the depth or area of an indentation left by an indenter of a specific shape, with a specific force applied for a specific time. There are three principal standard test methods for expressing the relationship between hardness and the size of the impression; these are brinell, vickers, and rockwell. For practical and calibration reasons, each of these methods is divided into a range of scales, defined by a combination of applied load and indenter geometry. Metus ndt services provides portable digital hardness testers for quick and convenient on-site hardness testing. We provide quick and inexpensive testing to determine if: metals meet required hardness readings for applications a metal component has been improperly heat treated pieces do not conform if pieces do not conform, we sort them for proper conditioning. Parts can be salvaged and brought back into specifications by the proper heat treatment or annealing process.

A hard oxide coating will gradually build up on the inside of power generation boiler tubes. Thicker the oxide layer, less efficient is the boiler and the additional heat build-up will shorten the life of the boiler. Benefits at a view: measure thinner oxidescale layers measure oxide on thick wall boiler tubes save a-scan and instrument parameters in data sets use “compare mode” to view set-up standard against actual measurement high display resolution and range allows for clear signal interpretation and resolving the measurement our solution: the object of the test is to perform a separate thickness measurement of the steel tube wall and the oxide scale layer located on the id of the tube. The interface echo from the tube-to-oxide is much smaller than the echo from the oxide-to-air interface and thus, the difficulty is separating these two echoes from each other and making the measurement between the two echoes using a highly damped “alpha” type straight beam shear wave probe is the key to obtain thin oxide layer measurements. The shear waves have half the velocity of l-waves which doubles the time resolution and enables the system to measure thinner layers than with conventional l-wave probes.

Acoustic emission may be defined as a transient elastic wave generated by the rapid release of energy within a material. Materials "talk" when they are in trouble: with acoustic emission equipment you can "listen" to the sounds of cracks growing, fiber breaking and many other modes of active damage in the stressed material. Small-scale damage is detectable long before failure so, ae can be used as a non-destructive technique to find defects during structural proof tests and plant operation. Ae also offers unique capabilities for materials research and development in the laboratory. Finally, ae equipment is adaptable to many forms of production qc testing, including leak detection. Some typical applications of the acoustic emission principle in testing materials are as follows: behaviour of materials such as metals,ceramics,composite,composites, rocks etc. Crack propagation yielding fatigue corrosion, stress corrosion creep fiber fracture, delamination metus ndt services offers a complete on-site inspection services performed with state-of-the-art computer-based systems by asnt certified operators and technicians.

Reference standards must be maintained. Depth of penetration is limited for all materials. Flaws that lie parallel to the probe coil winding and probe scan direction are undetectable.

Inspection of lagging integrity. Roof moisture analysis heat lossgain analysis why is it beneficial for you? by identifying these electrical anomalies before it develops into a more serious problem, disruption in your production due to failure of these equipment or components are reduced. Mostly undetected electrical anomalies can lead to electrical short circuit which can cause fire. A technical report will be given on the anomalies found during the survey which details the location of the anomaly, the criticality of the anomaly and the recommended actions to be taken to rectify the anomaly. A rescan will also be provided to ensure that the rectification works carried out on the anomalies have been executed effectively.
