ITE offers Helium Leak Testing (HLT) for wide varieties of components like Valves, Pressure Vessels, Heat Exchangers, Condensers, Tanks, Cryogenic Vessels, etc.

Leak testing is employed to detect leaks and determine the rate at which a fluid i.e. a liquid or gas will penetrate from inside a tight component or assembly to the outside or vice versa as a result of pressure differential between the two regions or of permeation of somewhat extended barrier. It has become conventional to use the term “leak” to refer to an actual discontinuity or passage through which a fluid flows or permeates. “Leakage” refers to the fluid that has flowed through a leak. “Leak rate” refers to the rate of fluid flow per unit of time under a given set of conditions, and is properly expressed in units of mss per unit of time. Standard leak rate refers to the rate of flow o atmospheric air under conditions in which inlet pressure is 0.1 Mpa ±5%; outlet pressure is leass tha 1 Kpa; temperature is 298K±5 and dew point is less than -298K.

The term “minimum detectable leak” refers to the smallest hole or discrete passage that can be detected and “minimum detectable leak rate” refers to the smallest detectable fluid flow rate. The amount of leakage required for a leak testing instrument to give a minimum detectable signal can be determined. This amount is generally used to denote the sensitivity of the instrument. Instrument sensitivity is independent of test conditions, but when an instrument is applied to a test, the sensitivity of the test depends on the existing conditions of pressure, temperature and fluid.

In order to serve our customers better, we (on continual basis) keep on incorporating advance testing techniques. There are various challenges faced by power plants to keep them running without abrupt breakdowns. One of the most common causes of this is leakage of boiler tubes. Generally the boiler tube joints are tested using RT but getting RT done in itself is not that simple. It requires a lot of regulatory clearances in the first place. Once RT starts, no other activity can continue due to probable risk of exposure to GAMMA Radiation. One technique has evolved over a period of time that has been used by numerous power plants now for checking boiler tube joints and the technique  is Phased Array Ultrasonic Testing (PAUT) of boiler tubes using COBRA scanners.

We have been offering Phased Array Ultrasonic Testing (PAUT) for welded joints including those of Boiler Tubes using an advance/portable PAUT equipment and required scanners. The advantages of the technique are as follows:

·        Highly sensitive technique

·        Multiple angles are fired at a single time using single phased array probe. Hence, probability of detection is increased over conventional UT.

·        Shorter scanning time.

·        Provision for replacement of RT with PAUT.

·        Results are storable and transferrable as digital copies

·        With the help of COBRA SCANNER, boiler tubes joints can also be inspected reliably and timely.

·        Unlike RT, area need not be cleared for testing the joint because no harmful radiations are not generated in PAUT. Hence, production delays are minimised.

·        Is used vigorously by private and state power companies and is highly acceptable.ITE offers these Non Destructive Testing services (NDT) at various places across India which include, Delhi, Uttar Pradesh (Ghaziabad, Sahibabad, Greater Noida, Noida, Lucknow, Agra, Kanpur, Mathura, Jewar, Sikandrabad, Meerut, Sonbhadra, Pata, Anpara, Allahabad, etc.), Madhya Pradesh, Punjab, Rajasthan, Haryana, Himachal Pradesh, Uttarakhand, Bihar, Chattisgarh, Gujarat, Maharashtra, Jammu Kashmir, West Bengal, Nepal, Sikkim, Arunachal Pradesh, Assam, etc.

Helium Leak Testing could be used to determine leakages in condenser unit of any power plant.

There are various challenges faced by the teams looking after the operation of turbines in any power plant. The most common of such challenge is maintaining proper vacuum in the condenser to ensure proper output. If the vacuum gets reduced below certain point due to any leakage, then the turbine cannot generate sufficient or desired electricity it is designed for. This leads to significant loss of revenue. Over a period of time, ITE Has developed capabilities in providing solutions to the customers in identification of Air Ingress Points throughout the negative pressure part of the condenser unit just below the turbine without the need of switching of the turbine. The system could be tested in the running condition and areas could be identified for repair and maintenance at the next opportunity. Helium Gas is used as a tracer gas which is sprayed over the areas suspected for leakages. If there is any leakage, the helium gas will be sucked in the system and detected at the exit point where Sniffer probe of the Helium Leak Detector is held. ITE has been providing these Online Condenser Leak Testing services also sometime referred as Negative Pressure Part Online Leak Testing to organizations like NTPC, Gujarat State Electricity Corporation Limited, Madhya Pradesh Power Generation Corporation Limited, etc. to name a few.

Fugitive Emission Testing is done on valves as per ISO 15848 Part 1 and Part 2. Part 1 is for Type Testing of valves while part 2 is for Production Testing of valves. Helium gas is used as the tracer gas. In the type test, the valves is tested for its endurance, tightness and temperature capabilities.

Personnel or operator performing the FET are ASNT SNT TC 1A certified Level II in Leak Testing

Diffraction is a common ultrasonic phenomenon and occurs under much broader conditions than just longitudinal-longitudinal diffraction as used in typical TOFD examinations. This interpretation guide is primarily aimed at longitudinal-longitudinal diffraction TOFD setups using separated transducers on either side of the weld on a plate, pipe, or curved vessel. Other possibilities include:
·        shear-shear diffraction
·         longitudinal-shear diffraction
·        single transducer diffraction (called "back diffraction" or the "tip-echo method
·        twin transducer TOFD with both transducers on the same side of the flawed weld complex inspections, e.g., nozzles
 
Although time-of-flight diffraction can be used for a variety of applications, it is primarily used for weld testing of circumferential and axial welded joints, also known as perpendicular TOFD scanning. Since the time of introduction of TOFD, the use of this non destructive testing technique has steadily increased. Manual execution is possible with TOFD, however, it is most commonly performed in combination with a recording device like an encoder or/and a scanner. To achieve certain code compliance, TOFD is sometimes coupled with pulse-echo or phased array techniques in order to cover the root and cap regions of the weld.

EDDY CURRENT INSPECTION OR EDDY CURRENT TESTING (ECT) is one of the Advanced Non Destructive Testing (NDT) methods which is based on the principles of electromagnetic induction and is used to identify or differentiate among a wide variety of physical, structural, and metallurgical conditions in electrically conductive ferromagnetic and non ferromagnetic metals and metal parts. Eddy current inspection can be used to:

• Measure or identify such conditions and properties as electrical conductivity, magnetic permeability, grain size, heat treatment condition, hardness, and physical dimensions

• Detect seams, laps, cracks, voids, and inclusions

• Sort dissimilar metals and detect differences in their composition, microstructure, and other properties

• Measure the thickness of a nonconductive coating on a conductive metal, or the thickness of a nonmagnetic metal coating on a magnetic metal

Because eddy currents are created using an electromagnetic induction technique, the inspection method does not require direct electrical contact with the part being inspected. The eddy current method is adaptable to high-speed inspection and because it is nondestructive, can be used to inspect an entire production output if desired. The method is based on indirect measurement, and the correlation between the instrument readings and the structural characteristics and serviceability of the parts being inspected must be carefully and repeatedly established

At ITE, we use Olympus MS 5800 for Eddy Current Testing of Tubes in various components like Heat Exchangers, Reactors, Condensers, etc. All those tubes which are non ferromagnetic in nature like made from the alloys of Aluminium, Copper, Austenitic Stainless Steel, Titanium, etc. are tested. We have a formidable customer base for ECT like IOCL, NFL, KSFL, NPL, IFFCO, etc. to name a few.
