RFT Single-Driver Flexible Probes
Flexible remote field testing probes inspect ferromagnetic tubing, including tight U-bends, for corrosion, erosion, wear and pitting.
Product overview
RFT Single-Driver Flexible Probes use remote field testing to inspect ferromagnetic tubing, including carbon steel heat exchanger tubes. Their driver and receiver modules are configured for absolute signal analysis to detect common tube degradation.
The driver and receiver modules are welded onto a flexible stainless steel shaft, creating a waterproof, wear-resistant assembly designed to traverse an entire heat exchanger U-bend tube in a single pass. The design accommodates 180° U-bends with radiuses as small as 88.9 mm (3.5 in) and supports defect detection in bent sections of ferritic tubes.
Typical inspection targets include feedwater heaters, heat exchangers and ferromagnetic piping affected by corrosion, erosion, wear or pitting. A probe-head preamplifier, highly kink-resistant cable and low-friction-noise design support these tubing inspections.
Key capabilities
Flexible U-bend traversal
The flexible shaft allows inspection of a whole heat exchanger U-bend tube in a single pass.
Probe-head preamplifier
A 30 dB preamplifier is incorporated in the probe head.
Durable construction
A welded stainless steel head and flexible shaft provide waterproof, wear-resistant construction.
Kink-resistant cable
The cable is designed for high resistance to kinking.
Absolute signal analysis
The probe design is optimized for absolute signal analysis.
Low friction noise
The design provides low friction noise during tube inspection.
Bent-section defect detection
The probe design enables detection of defects in the bent sections of ferritic tubes.
Amphenol connection
The probes use a 19-pin Amphenol connector.
