A Joint Approach to Boiler Tube Failure Prevention


JA Educational TrainingJA 02JA 03

Our Joint Approach to Boiler Tube Failure Prevention course is an insightful informal class presentation examining the positive results in the identification process for prevention of tube failure occurrence utilizing the combination of “in-the-field” inspection and laboratory analysis of previously failed boiler tubes. Some of the topics include cycling the boiler, operational upsets and resulting damage, quench cracking from water lances/cannons, and direct strategies for approaching these problems. The effects of fuel changes, burner retrofits, i.e. fireside corrosion; causes, methods of prevention and acceptable repairs are also covered. Discussion of the importance of a good water chemistry program, acid phosphate corrosion, caustic corrosion/gouging, copper deposition, and hydrogen damage, as well as pitting, scale and water side contaminants; to include causes, preventions, and acceptable repairs are all part of the curriculum. Common boiler materials, fabrication, installation defects, graphitization, low temperature creep, and boiler lay-up procedures are also included among the topics. This seminar is a must for maintenance personnel as well as operators and plant managers to provide knowledge for implementation of strategic failure prevention maintenance solutions based on conclusive findings reported through metallurgical analysis for failed tubes. The seminar will include the following topics in discussion: 

Introduction to Metallurgy - Atoms - Crystals and Grain Boundaries - Iron and Steel - Heat Treatment - Stainless Steels - Creep  Inspection Methodology and Repair Practices - Steam Side Scale - Water treatment
