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.

Oxide Scale Measurement is generally used for detetion of deposition of oxides on the inside of the tubes used in power plants.

A significant limiting factor that affects tube life in fossil fired steam boilers is the growth of iron oxide scale (magnetite) on the inside and outside tube surfaces. The oxide scale, which forms under long term exposure to very high temperatures, acts as a thermal insulator. While external scale limits heat transmission into the tube and reduces boiler efficiency, internal scale buildup represents a potentially more serious problem. The insulating effect of internal scale limits heat transmission into the water vapor inside the tube, which in turn causes chronic overheating of the tube wall and promotes accelerated metallurgical failure. Non Destructive measurement of internal oxide scale thickness is of major interest in the power generation industry and other users of fossil fuel steam boilers, since scale thickness may be used to predict remaining tube life. While very high frequency ultrasonic gaging techniques have been available for this measurement for a number of years, they involved use of cumbersome, expensive pulser/receiver and oscilloscope systems. Recent advances in instrumentation technology have made available small, hand-held ultrasonic gages with software optimized for measurement of internal scale and advanced data logging capability. Additionally, the use of normal incidence shear wave transducers improves resolution of thin scale layers, permitting measurement of scale buildup down to approximately 0.125 mm with hand-held equipment. ITE has uses Olympus 38 DL plus with suitable probes for testing of tubes for deposition of oxide scales. We have been providing these services for more than a decade and have various customers across the country in Power Sector who regularly use our services.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, moradabad, gajraula, hapur, etc.), Madhya Pradesh, Punjab, Rajasthan, Haryana, Himachal Pradesh, Uttarakhand, Bihar, Chattisgarh, Gujarat, Maharashtra, Jammu Kashmir, West Bengal, Nepal, Sikkim, Arunachal Pradesh, Assam, etc.

Internal Rotatory Inspection System or IRIS is used of inspecting the internal of tupes/pipes which otherwise are not accessible for testing with any other methods. Unlike Eddy Current Testing or RFET, it can tell us the exact thickness of the are under inspection and the flaw itself.

With Internal Rotary Inspection System, we can detect corrosion, pitting and wall loss and is commonly used for tube inspection in boilers, heat exchangers, air coolers and feed water heaters. It is particularly versatile as it is suitable for both ferrous and non-ferrous materials, and IRIS can be used on a wide range of tube diameters and wall thicknesses. 

An IRIS probe is inserted into a tube flooded with water. The probe is fitted with a turbine and a transducer that generates an ultrasonic pulse along a path parallel to the axis of the tube. A rotating mirror directs the ultrasonic pulse into the tube wall. The mirror is driven by a small turbine that is rotated by the pressure of water pumped into the tube.

Ultrasonic Pulses are reflected from the outer dia of the tube and then return to the IRIS probe/sensor and gives us the indication of flaw, if any.

As the IRIS probe is pulled, the spinning motion of the mirror results in a helical scan path ensuring full coverage of the tube.

Benefits of using IRIS include:

Suitability for both ferrous and non-ferrous material

Detection of corrosion, pitting and thickness lo

Accurate wall thickness measurement

Sensitivity to both internal and external defect

Defect position can be located in relation to tube length

Complete coverage of the tube

Results data storage

Flexibility as a back-up to remote field, magnetic flux leakage and eddy current inspections.
