Heaters, Boilers, Heat Exchanger and associated piping operate under various kinds of static and dynamic stresses, both thermal and mechanical. In addition to this the type of fluid plays an important role in analyzing such failures. The fluids flow at high velocity and many a times under turbulent conditions. Induced thermal stresses and vibrations demand careful selection of material and design. Failure in such equipment can occur due to both manufacturing deficiencies and operational mistakes among other factors. AEIS metallurgists and engineers have hands on experience in refineries and petrochemicals and understand exactly how the equipment operates under normal and abnormal conditions. AEIS failure analysts have top-notch expertise in analysis of heaters, boilers, heat exchangers, pressure vessels, reactors, drums, storage tanks and other ancilliary equipment. AEIS personel have analyzed failures due to creep, fatigue, corrosion, hydrogen damage, stress corrosion cracking, wear etc. for refineries, research outfits, and chemical companies. AEIS investigation on Heaters, Boilers and Heat Exchanger and associated piping involves detailed analysis of the various parameters that may have led to the failure of the equipment.

Some of the recent failures analyzed were:

• Failure of a green house boiler that failed due to fabrication mistakes
• An eleven section residential boiler that failed because of water starvation
• Floating head bolts of eight heat exchangers that failed soon after chemical cleaning
• An oil pump that failed due to wear by solid contaminants
• A critical pipe line reducer that failed from excessive flow velocities.
