Driving industrial plant performance through Advanced Non-destructive Testing (ANDT) methods
The ever-growing global demand for electricity and industrial production capability is putting significant pressure on our ageing industrial infrastructure. In an increasingly competitive marketplace, industrial plant owners and operators simply cannot afford plant downtime. Advanced Non-destructive Testing (ANDT) services utilize advance instrumentation based on latest software and hardware technology to perform NDT testing of critical components.
Several Advanced NDT methods can be used to perform in-service inspection of plant assets. These critical plant assets are tested for fitness during shutdowns, with the use of Advanced NDT methods, testing can be performed in less time and quantitative data can be obtained to take the necessary course of corrective actions by plant operators to avoid in-service failures and to further enhance productivity.

Tool for rapidly inspecting long lengths of pipelines from single location.
Unlike conventional ultrasonic inspection method, LRUT screens pipelines 360 degrees to locate discontinuities for further verification by saving time and money.
Combination of multiple wave modes assures operators about finding longitudinal as well as circumferential discontinuities.
When low frequency waves (15 kHz to 85 kHz) are propagated from a single location, it can reach up to several meters of distance and inspection data can be captured, interpreted, stored and reported in advanced software.
Features and Advantages
Possible to inspect diameters from 2” up to 24”.
Possible to inspect wide temperature ranges: 0 to 70-degree C.
Road crossing, river crossing, Dyke, culvert and in-cased pipelines
Off-shore and jetty pipelines
Pulsed Eddy Current Testing is saving huge amount of money and time for operators while inspecting plant equipment's or components which are insulated. It is very difficult to perform inspections on coated, insulated surfaces; PECT makes it easy by measuring thicknesses through insulation. This electromagnetic principle based instrument works on battery and stores inspection data which can be easily converted into tabulated format for reporting purpose. In 1 working day, we can inspect up to 500-600 inspection points.
Features & Advantages
Possible to inspect diameters from 1” up to flat surfaces
Possible to inspect thickness up to 100 mm
Possible to inspect wide temperature ranges: -100 to 650-degree C

Storage tanks of petroleum, fire water or vegetable products are prone to soil side corrosion over long duration in operation. As a severe consequence; tank starts leaking from bottom or from shell, resulting in emergency turnarounds. Despite routine inspections, operators miss spots of corrosion due to conventional methods of inspection. Using MFL plate scanner, we can scan 100% of the bottom plate surface and detect soil side corrosion at an early stage before it leaks.
Features & Advantages
Variable speeds: 500 mm/s to 1 m/s (19.7 in/s to 3.3 ft/s)
Through-coating inspection up to 6 mm (0.24 in), including fibre-reinforced plastic (FRP), glass-reinforced plastic (GRP), and stainless steel

Bubble leak (or vacuum box) testing is an integral part of tank inspections as required by the American Petroleum Institute (API) and other international standards.
System is more efficient, reduces operator fatigue, increases operator safety. System incorporates calibrated vacuum gauge with flat and corner weld inspection models.
RMS2 is a high-speed, high-accuracy remote-access ultrasonic corrosion mapping system. RMS2 offers 100% coverage in a band up to 1 m wide, significantly increasing the probability of detection (PoD) of defects, enabling engineers to determine optimal repair strategies, and improve remaining life assessment (RLA) and risk-based inspection (RBI) maintenance programs.

Phased Array Ultrasonic Testing (PAUT)
A power full ultrasonic testing tool which is replacing Radiography in many applications.
A phased array system is normally based around a specialized ultrasonic transducer that contains many individual elements (typically from 16 to 256).
Test frequencies are most commonly in the range from 1 to 10 MHz.
Features & Advantages
The benefits of phased array technology over conventional UT is that it can steer, focus and scan multiple element beams with a single transducer assembly.
Battery operated – Battery lasts 6-7 hours.
Simplicity in inspecting components with complex geometry.
Increased probability of detection of anomalies.
Possible to inspect ¾ diameter to flat surfaces.
Possible to inspect minimum 5 mm thickness.
Ability to focus at multiple depths improving the ability for sizing critical defects for volumetric inspections.
Time of Flight Diffraction (TOFD)
Primary use is rapid weld testing of circumferential and axial weld seams.
In many applications PAUT and TOFD is carried out in combination.
Ultrasonic sensors are placed on each side of the weld. One sensor sends the ultrasonic beam into the material and the other sensor receives reflected and diffracted ultrasound from anomalies and geometric reflectors.
Excellent and highly sensitive tool for detecting welding flaws/cracks.
Features & Advantages
Uses time of arrival of signals received from crack tips for accurate defect positioning and sizing.
Precise sizing capability
Quick to set up and perform an inspection, as a single beam offers a large area of coverage
