What causes failure of boiler tube? - FindAnyAnswer.com

Apr 18, 2020 · Erosion is a process of wear in which materials are removed from a solid surface by the action of solid particles impinging on it. Fly ash erosion is the second most important cause for boiler tube failure (DOE, 1998). Tube failures by erosion in some cases account for about one-third of all tube failures in a boiler.

Caustic Embrittlement - The Online Hub for Corrosion

Feb 14, 2020 · The hydroxide then attacks the surrounding material of the boiler and dissolves iron as sodium ferrite. This corrosion at high pH levels produces hydrogen, which attacks the crystal structure of iron, making it hard and brittle. This is highly dangerous because the tube can then fail at the boiler's normal operating temperature.

Boiler Feedwater Deaeration: How To Keep Your Steam System

How boiler feedwater deaeration is done. Water at 70°F could contain oxygen at 8.6 ppm and water at 150°F could contain oxygen at 4.3 ppm. Oxygen content of 7 ppb is generally accepted by the ASME, but your boiler supplier should specify what level is ideal for operating their equipment. Heat is the most common method for removing oxygen.

Caustic attack on boilers is a localized attack due to extremely high pH (12.9 +). It can take two forms: caustic gouging or caustic cracking, also called caustic embrittlement. Caustic attack or caustic corrosion, is often encountered in phosphate treated boilers in which deposits of phosphates or other 'scale' occur in high heat transfer
