Remote Visual Inspection (RVI) in Chennai
High-definition articulating videoscopic inspection of inaccessible internal piping, turbine interiors, valves, and enclosed cavities in Chennai.
Certified Level II inspector performing Remote Visual Inspection. LEVEL II / III
Overview of Remote Visual Inspection (RVI)
Detailed testing capabilities provided by NP Technical Services Pvt. Ltd. from our West Tambaram, Chennai facility.
Remote Visual Inspection utilizes industrial video probes with 4-way articulation and high-intensity illumination to inspect internal bores, tube bends, turbine blades, and weld roots without component disassembly.
An industrial videoscope probe featuring a miniature high-resolution CCD/CMOS sensor and fiber-optic LED illumination is guided into inaccessible cavities using 4-way joystick articulation. High-definition color video and still images with stereo 3D flaw measurement are captured directly onto digital storage for engineer review.
Certified Technical Execution Across Tamil Nadu
Every Remote Visual Inspection assignment is executed adhering to approved written procedures, client inspection test plans (ITP), and certified Level II & Level III oversight.
