Boiler Tube Inspection

Can anyone suggest a method of inspection for ferritic steel boiler tubes, in a fire tube boiler with access to fire side (tube I.D.) only. Material excessively noisy with RFET and flooding is not permitted.

Re: Boiler Tube Inspection
Good Day Nick,

LOTIS which is a "laser based" inspection method has been applied to boiler tubes for nearly 20 years. This method does not care what the material type is and is not effected by any external attachements (i.e. fins, etc.). Please let me know if you would like more information.

Re: Boiler Tube Inspection
Hello Nick,

what type of defects are expected? You are looking for pitting corrosion, cracks or erosional defects? We are eddy current experts and have carried out serveral
types of inspection without using RFET! Please tell us something about the dimensions to make any special recommendations.

Best regards

Re: Boiler Tube Inspection
I have a question about the LOTUS method: Does it detect any defects that may be on the tube OD? I was under the impression that it only finds ID defects.

Thank you.

l - as well as oil and gas transportation industry. The sensor system is designed for permanent monitoring or periodic inspection tasks. Sensors are available for different AE-frequency ranges optimized for corrosion and fatigue crack detection and other applications. The ISAFE 3 sensor system consists of an AE-sensor (model ISAS3) certified according to ATEX/IEC for installation in zone 0, gas group IIC, IP68, 20 to +60 °C, and a signal isolator (model SISO3) certified for installation in zone 2. An ISAS3 sensor can be mounted in atmosphere or submerged, e.g. in water or crude oil. It is supported by mounting tools for temporary (magnets) or permanent (welded) installation. ISAFE3 supports automatic sensor coupling test and can be used with any AE signal processor supporting 28V supply at 90 mA peak, e.g. Vallen Systeme ASIP-2/A.
