Boiler inspection Procedure requirement and Recommendations

May 30, 2018 · Boiler tubes can be internally inspected by a fiberscope type of instrument that can give a TV picture of the inside of the tubes. Sometimes sections or tubes may be cut out for inspection and replacement. Internal boiler scale (deposits) may indicate the need for chemical cleaning. The tube in Figure 3 is in definite need of chemical cleaning.
