Revolutionizing Non-Destructive Testing: The Clamshell Eddy Current Multichannel Probe

Revolutionizing Non-Destructive Testing: The Partial Clamshell Eddy Current Multichannel Probe

Efficiency is key across the power generation industry, and steam power plants are at the forefront of electricity production. However, ensuring the integrity of critical components like superheater tubes in subcritical and supercritical boilers is a constant challenge. Below, we will explore how Russell NDE's new Clamshell Eddy Current Multichannel Probe is changing the game in non-destructive testing (NDT) for power plants and supercritical boilers. Continue reading to find out more. 


The Challenge: Superheater Tubes in Supercritical Boilers

Steam superheater tubes, located at the upper half of supercritical boilers, face extreme temperatures, making them susceptible to internal and external corrosion and ash erosion. Traditional inspection methods are often very slow, leading to costly downtime and operational disruptions. However, Russell NDE has designed an innovative eddy-current array solution to mitigate this challenge. 


The Threat: Internal and External Pitting Corrosion, Ash Erosion and cracking.

For facilities that utilize supercritical boilers, avoiding downtime is critical. Superheater tube failures due to corrosion, cracking and erosion are a leading cause of forced outages in these types of boilers worldwide. However, the Partial Clamshell Eddy Current Multichannel Array Probe from Russell NDE promises to change this by ensuring more complete and faster NDT inspection coverage.

Stainless steel superheater tubes are at risk of internal and external pitting corrosion. Detecting these issues in a timely manner is crucial to prevent costly tube failures. Russell NDE's Partial Clamshell Probe is designed to address internal and external corrosion pitting challenges.


The Innovative Solution: Partial Clamshell Eddy Current Multichannel Array Probe

Designed for stainless steel superheater pendant tubes in supercritical boilers, Russell NDE's Partial Clamshell Probe offers a groundbreaking solution. It wraps around tubes, enabling the NDE crew to inspect the superheater pendants with minimal disruptions in operations. This efficient, non-destructive testing system can spot signs of corrosion, erosion and cracks providing comprehensive data regarding the status of your superheater tubes. 


The Technology Behind the Partial Clamshell Probe: ECT and the Ferroscope 308

Unlike traditional magnetic inspection methods, the Partial Clamshell Probe employs Eddy Current Technology (ECT) to identify defects quickly and accurately. This technology is particularly effective for inspecting non-ferrous materials like stainless steel, making it an ideal fit for this type of superheater tube inspection.


In conjunction with Russell NDE's Partial Clamshell Eddy Current Multichannel Array Probe, the Ferroscope 308 RFT / ECT System has set the non-destructive testing bar high. The Ferroscope 308 system is a versatile instrument designed for the non-destructive inspection of ferrous and non-ferrous heat exchanger tubes. Its usage is extended beyond superheater tubes and into a wide range of applications in power generation, oil and gas, pulp and paper, and petrochemical plants. With exceptional pit detection capabilities, fast probe pull speed, user-friendly software, setup wizard and compliance with industry standards, Russell NDE's Ferroscope 308 system, when combined with the Partial Clamshell Probe, offers a comprehensive solution for inspecting critical components with precision, reliability, and efficiency, ultimately contributing to enhanced plant performance, reduced downtime, and increased operational reliability.
