Tube Inspection & Eddy Current Testing in Chennai
Specialized electromagnetic and acoustic internal tube inspection for condensers, heat exchangers, chillers, and boiler tubing in Chennai.
Certified Level II inspector performing Tube Inspection Techniques. LEVEL II / III
Overview of Tube Inspection Techniques (TUBE)
Detailed testing capabilities provided by NP Technical Services Pvt. Ltd. from our West Tambaram, Chennai facility.
Tube inspection utilizes specialized internal probes (bobbin coils, ultrasonic rotary probes) pulled through tubular heat exchangers to detect wall thinning, pitting, erosion, and stress cracking.
Specialized internal bobbin coils, internal rotary inspection system (IRIS) ultrasonic heads, or remote field testing (RFT) probes are inserted into tubes and pulled back with automated probe pushers. Real-time multi-frequency phase and amplitude curves detect internal and external diameter flaws, baffle cuts, and remaining wall thickness.
Certified Technical Execution Across Tamil Nadu
Every Tube Inspection Techniques assignment is executed adhering to approved written procedures, client inspection test plans (ITP), and certified Level II & Level III oversight.
