NDT SERVICES IN CHENNAI

To improve manufacturing quality and product reliability, components and structures are regularly inspected for discontinuities, defects or faults which may reduce their structural integrity leading to failure. Among the material testing methods developed for inspection purposes, Non-destructive testing (NDT) techniques present the advantages of leaving the components undamaged after inspection. TWG GROUP NDT inspection facilities are equipped with modern NDT equipments, approved practices, procedures, qualified and certified NDT Level I, II, technicians and in-house ASNT NDT III certified professionals, materials testing experts, welding inspection and quality control personnel.

Ultrasonic Testing

Ultrasonic testing in chennai(UT) is carried out for evaluating the internal soundness of many engineering products made of steels and other metals and nonmetals processed through Casting, forging, rolling, extrusion, drawing and other modern processing techniques. Ultrasonic inspection is also extensively being used for evaluating the quality of welds, in-service inspection of critical process equipments, storage tanks, cross country pipelines, pressure vessels and assemblies. TWG GROUP NDT is fully equipped with calibrated, latest DGS Ultrasonic equipments, qualified, certified and experienced Level I, II technicians, ASNT NDT level IIIs, experts to carry out these tests and other related services within the shortest possible response time.

TWG GROUP NDT's experienced teams have highly skilled professional inspectors, modern stationery , mobile, stationery, portable type of equipments suitable for high productivity inspections and field tests and NDT Level III experts to provide consultation, technique establishing, procedure preparation and related services.Magnetic particle testing (MT) also called as magnetic crack detection, Magnetic particle inspection (MPI) is one of the most effective method for finding both surface and subsurface or near surface flaws in ferrous materials at various stages of manufacturing.

Radiography Testing

Radiography testing in chennai is carried out using X-rays or Gamma rays. Radiographic testing (RT) is one of the most reliable and widely used NDT methods in industries. Works on the principles of differential absorption of radiation, radiography is used to detect internal flaws in castings and welds. Additional advantage with Radiography is the availability of permanent record for future reference.

Eddy Current Inspection

In eddy current testing in chennai electrical currents are generated a conductive material by an induced magnetic field. Distortions in the flow of the electric current (eddy currents) caused by imperfections or changes in a material’s conductive properties will cause changes in the induced magnetic field. These changes, when detected, indicate the presence of the imperfection or change in the test material.In eddy current testing electrical currents are generated a conductive material by an induced magnetic field.

Visual Testing

Visual testing in chennai (VT) is one of the oldest and most widely used NDE methods to derive a multitude of useful information from a variety of material characteristics and properties. Visual examination is used in all stages of manufacturing and fabrication as a means of verifying conformance to standards and ensuring the quality levels are met and maintained in the final product. A great deal of specialized equipments, certified inspectors as per ASNT recommended practice SNT-TC-1A, technicians and NDT level III's exists for this purpose and can provide ASME 'U' stamp consultation on NDT.A great deal of specialized equipments, certified inspectors as per ASNT recommended practice SNT-TC-1A, technicians and NDT level III's exists for this purpose and can provide ASME 'U' stamp consultation on NDT.

Infrared and Thermography

Thermography testing in chennai enables the thermal profile of an item, machine or building to be presented in a graphic from which allows a working temperature assessment to be derived. From this, variations in the material or component temperature are identified, enabling working limits or corrective actions to be identified.
