Non-destructive testing (NDT) covers a diverse range of techniques designed for assessing the integrity of materials, most typically metals. Applications include evaluating compliance of fabricated items with material specifications and identifying degradation which can occur during the service life of equipment or structures.
Ultrasonic Inspection is very sensitive test method for detection of embedded linear discontinuities. Ultrasonic testing is faster and economical as compared to radiographic examination.
The common applications of ultrasonic testing are wall thickness measurement, corrosion mapping, lamination testing , flaw (discontinuities) detection in the material e.g. welds, castings, forgings and other wrought products, density measurement of material, hardness measurement, etc.
We can provide equipment and personnel to carry out ultrasonic testing on a wide range of weld configurations and materials.
- Welds, plate, pipe, beams, T joints, TKY joints
- Castings, forgings, metal bearing bonds.
- Lamination checks, plate scans, full floor scans, prepped joints prior to welding.
- Thickness testing, ship hull surveys, tank inspection.
Dye Penetrant Inspection
Dye Penetrant Inspection (DPI) also called as Liquid Penetrant Inspection (LPI) is fast, economical and widely used non destructive test method to detect surface-breaking discontinuities in all non-porous materials (metals, plastics, or ceramics).
Penetrant test is performed by cleaning the test surface thoroughly, applying coloured or fluorescent penetrant, allowing penetration time, removal of excess penetrant followed by application of developer ( dry or liquid form). The developer assists to draw penetrant out from the surface breaking discontinuities.
After developer dwelling the test surface is examined for bleed out under natural light or black (UV) light.
