Metal Finishing Services

Indogulf provides basic NDT services and advanced inspection services as given below which finds application with respect to international standards like AWS, ASME, API, ASTM, DIN, ISO, BS, ANSI, NACE, Marine classifications like DNV, BV, LRS, RINA, GL, TUV etc in areas of structural steel works, Piping, Pressure vessels, Tanks, castings etc. With operations spread out in different parts of GCC, our laboratory is fully equipped to carry out the following NDT services both onshore and offshore. Magnetic Particle Inspection Dry method & Fluorescent method. Ultrasonic Flaw Detection. Ultrasonic Thickness gauging. Dye Penetrant Test. Ferrite Measurement. Radiography Test. Positive Material Identification. Coating Thickness Measurement. Heat Treatment Services. X-Ray & Gamma Ray pipe crawler systems. Borescope Inspection. Vacuum Box Test.

Non-destructive testing (NDT) is a testing and analysis technique employed to evaluate the properties of a component and its structure for characteristic differences or welding defects and discontinuities without causing damage to the original part.Our NDT specialists are highly qualified professionals who can assist you in meeting the inspection challenges that arise with complex components or structures and increase the detection of defects. Thus, we provide total quality assurance and help you avoid the loss of time and money due to in-service failure or manufacturing defects in new products or structures.

Accurate Edge offers 2 types of NDT process, MPI and LPI. MPI – Magnetic Particle Inspection is a method that is used for the detection of surface and near-surface flaws in ferromagnetic materials and is primarily used for crack detection. LPI – Liquid penetrant inspection is a low-cost inspection method used to locate surface-breaking defects in nonporous materials. Penetrant inspection is used to detect casting, forging and welding surface defects such as hairline cracks, porosity, leaks in new products and fatigue cracks on in-service components.

Destructive tests are carried out in the laboratory for specific application in close association with international client specifications on materials & welded specimens. Materials shall be certified for grade confirmation based on the evaluation of the test results. Welder performances are evaluated and certified & welding procedures are qualified by incorporating inspection, NDT & mechanical tests in accordance with international standards and client’s requirements. We carry out various mechanical tests like tensile test to find out the physical properties namely yield strength, tensile strength, elongation, reduction of area etc, Charpy impact test on full & sub size specimens to verify the toughness of material, hardness tests- Vickers, Rockwell, Brinell, Knoop at lab and at site, nick break test on materials and weldments. Macro examination of welded specimens is also carried out. We also perform metallographic test for close scrutiny of metallurgical structures of samples by evaluating the microstructure to establish phases on etching and their morphology. Grain size measurement & ferrite content shall be determined by evaluating the microstructure which will be reported with photographic proof. Replica technique is used for metallurgical services at site applications particularly for boiler tubes, heat exchanger tubes etc. Other corrosion tests to check susceptibility to intergranular corrosion, pitting corrosion, hydrogen induced, stress corrosion cracking under Sulphide, chloride atmospheres. Chemical analysis is carried out using wet method or atomic absorption (spectrometer) to determine the percentage of chemical elements present in metals. The major activities are as listed below
