Technical Scope & Inspection Capabilities
Completely non-destructive microscopic examination of metallic grain structure directly on operational components without cutting destructive samples. Examines carbide precipitation, thermal degradation, grain growth, decarburization, hydrogen attack, and micro-creep void cavitation.
Industrial Applications in Chennai
High-temperature boiler steam pipes, superheater tubes, cracking furnace coils, reformer tubes, and heavy turbine casings.
Frequently Asked Questions (Chennai Region)
What is the Neubauer classification for creep damage assessment?
Replicas are evaluated under the Neubauer / VGB-TW 507 scale: Class 1 (Isolated cavities), Class 2 (Oriented cavities), Class 3 (Cavity chains), Class 4 (Micro-cracks), and Class 5 (Macro-cracks), guiding remaining creep life estimation. Our teams serve facilities across Chennai, Chennai & Suburban Districts with Same-day Mobilization (< 2 hours).
Does field metallography damage the tested component?
No. The procedure only involves localized micro-polishing of a 25mm x 25mm spot down to 1-micron mirror finish and light chemical etching. The component remains 100% in service without reduction in pressure rating. Our teams serve facilities across Chennai, Chennai & Suburban Districts with Same-day Mobilization (< 2 hours).
