Penstock Inspections

Penstock NDT inspections are vital non-destructive evaluations that ensure the safety, efficiency, and structural integrity of penstocks in hydroelectric power plants. Using advanced techniques like UT, RVI, and MT, our experts detect flaws without disrupting operations.

Overview

Penstock inspections involve the non-destructive evaluation of large steel pipes that carry high-pressure water to hydro turbines. These inspections are crucial for identifying surface and internal defects such as corrosion, cracks, deformation, or thickness loss—issues that may compromise operational safety or efficiency.

Our specialists deploy a suite of NDT techniques, including ultrasonic testing, visual inspection, magnetic particle testing, and drone-based RVI (Remote Visual Inspection), to ensure accurate and detailed assessments across the full length of penstocks, even in confined or elevated environments.

With years of industry experience, our team ensures your hydro assets operate safely and remain compliant with international standards and regulatory requirements.

Common Questions

Get clear answers about how non-destructive testing helps ensure penstock integrity, plant safety, and regulatory compliance.

Penstock NDT inspections are non-invasive methods to assess the structural condition of water-carrying pipelines in hydropower plants using techniques like UT, MT, and drone-based visual assessments.

Common issues include corrosion, wall thinning, weld cracks, material fatigue, and surface deformities—often caused by aging, pressure stress, or water quality.

Frequency depends on age, operating pressure, past issues, and regulatory mandates. Critical or aging penstocks may need annual or biannual checks.

No. Most methods—especially RVI and UT—can be performed during scheduled maintenance or even partial operation windows.

Yes. Our inspections align with industry regulations and international hydro safety guidelines.

Yes. We use remotely operated vehicles (ROVs), drones, and robotic crawlers to inspect confined or submerged sections of penstocks, providing high-resolution visuals and real-time data without the need for manual entry.
