IIS is a subsidiary and mechanical Inspection division of under taking NDT of buildings,factories and maintenance works in all over India. Our company provides the NDT & WELDING services to the Oil , Gas and other industrial projects, and having its own and independent management. IIS provides the inspection services for Oil, Gas and other industrial projects, any location (Onshore and Offshore)
in India. IIS have an initial manpower of 20 NDT/WELDING technicians and company will increase the manpower as and when is required. All NDT technicians are qualified ASNT Level II multi discipline and capable to work in various projects such as Power plants, Petrochemicals, Fertilizer, Refinery and other petroleum projects, cross-country pipelines, onshore and offshore structural jobs. IIS established with an adding various testing and inspection equipments to upgrade our services assessing the increased day to day requirement of NDT and WELDING Services in the region. SERVICE PROVIDED
We are providing the following services executed by our skilled and well experienced technicians retaining high Quality and accuracy on our ‘Right first’ policy basis. Some Basic Info about our NDT world-by- www.intechin.co.in
Nondestructive testing - NDT - use test methods to examine an object, material or system without impairing its future usefulness. Non-destructive testing is often required to verify the quality of a product or a system. Commonly used techniques are
AET - Acoustic Emission Testing
ART - Acoustic Resonance Testing
ET - Electromagnetic Testing
IRT - Infrared Testing
LT - Leak Testing
MT - Magnetic Particle Testing
PT - Dye Penetrant Testing
RT - Radiographic Testing
UT - Ultrasonic Testing
VT - Visual Testing (VI - Visual Inspection)
AET - Acoustic Emission Testing
Acoustic Emission Testing takes advantage of the sharp sound that PCCP emits when it breaks or slips to identify areas of active distress within a construction. AET can be used to verify the structural integrity of pressure vessels, spheres, high temperature reactors and piping, coke drums, above ground storage tanks, cryogenic storage tanks and more. The inspection is executed externally and shut-down of the process may often not be necessary. ART - Acoustic Resonance Testing
After an impact a specimen will vibrate in certain characteristic modes and frequencies that can be measured by a microphone or laser vibrometer. Acoustic sonic and ultrasonic resonance analysis is a non-destructive testing technique that allows testing of a wide range of test objects. Typical detecting faults are cracks, cavities, detached layers, material inconsistencies, hardness deviation in materials. ET - Electromagnetic Testing
Electromagnetic testing is the process of inducing electric currents and/or magnetic fields inside a test object and observing the response. A defect in the test object may be detected where electromagnetic interference creates a measurable response. IRT - Infrared Testing
Infrared testing is a technique that uses thermography, an infrared imaging and measurement camera, to see and measure infrared energy emitted from an object. Can be used to heat development, lack of insulation, thin walls in constructions and more. LT - Leak Testing
Techniques used to detect and locate leaks in pressure containment parts, pressure vessels, and structures. Leaks can be detected by using liquid and gas penetrant techniques, electronic listening devices, pressure gauge measurements or soap-bubble tests. MT - Magnetic Particle Testing
Magnetic particle testing is accomplished by inducing a magnetic field in a ferromagnetic material and then dusting the surface with iron particles. The surface will produce magnetic poles and distort the magnetic field in such a way that the iron particles are attracted and concentrated making defects on the surface of the material visible. PT - Dye Penetrant Testing
The dye penetrant testing can be used to locate discontinuities on material surfaces. A highly penetrating dye on the surface will enter discontinuities after a sufficient pe*******on time, and after removing the excess dye with a developing agent, the defects on the surface will be visible. RT - Radiographic Testing
Radiographic testing can be used to detect internal defects in castings, welds or forgings by exposure the construction to x-ray or gamma ray radiation. Defects are detected by differences in radiation absorption in the material as seen on a shadow graph displayed on photographic film or a fluorescent screen. UT - Ultrasonic Testing
Ultrasonic testing uses high frequency sound energy to conduct examinations and make measurements. Ultrasonic inspection can be used for flaw detection/evaluation, dimensional measurements, material characterization, and more. VT - Visual Testing (VI - Visual Inspection)
Visual testing or inspection offers a wide range of options to secure proper system or product quality.
