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.
