Waterwall Scanning From the Fireside Outside Diameter

TS 2000 NDT Multi-Channel System for Waterwall Scanning from the OD TesTex, Inc. has developed the TS 2000, an innovative multi-channel NDT system for the OD scanning of waterwall tubes and pendant superheater/reheaters. This system detects and quantifies defects from oxygen pitting, caustic gouging, hydrogen damage, flue gas/low NOx erosion, cracking, etc. Base metal can be penetrated up to 0.75 inches (19mm).

Advantages

No couplant required

Uniform rust and scale have no impact on the signal

Tests bends and elbows

Scanning speed of 10 to 15 feet (3 to 4.5m) per minute

Scanners and probe arrays are contoured to tube OD

Wide range of scanner sizes available, i.e. 1.0" to 4.0" (25.4 to 102mm)

Real time data display with advanced signal processing

High resolution color graphics with 3-D display

Inspection Procedures

Accessibility is provided by scaffolding the furnace cavity (hard, swing, stage)

Select internal functions such as gain and frequency to fit tube specifications

Choose area to scan

Move TS 2000 scanner along the length of the tube at a constant rate

View collected data in real time on the screen via the innovative SCAN software

Mark any flaw indications on the tube for later verification, if needed

Quantify flaws with the SCAN software

Results reported in percentage of wall loss or mils remaining

Full color final reporting showing flaw evaluation and depth is standard
