Stresses may be associated with vibration due to flue gas flow or sootblowers (high-frequency, low-amplitude stresses), or with boiler cycling (low-frequency, high-amplitude stress mechanism). Components typically affected : Fatigue failures will most often occur at areas of constraint such as tube penetrations, welds, or supports.

All about Carbon Steel Boiler Tubes. A boiler with a high-pressure water tube is a type of boiler in which water circulates in tubes externally heated by the gas. Inside the furnace, fuel is burned, producing hot gas that heats water in the tubes to produce steam. Carbon steels display modest tolerance to corrosion and equal strength up to 1000F.

The simplest form of flued boiler was Richard Trevithick's "high-pressure" Cornish boiler, first installed at Dolcoath mine in 1812. This is a long horizontal cylinder with a single large flue containing the fire. As the furnace relied on natural draught, a tall chimney was required at the far end of the flue to encourage a good supply of air (oxygen) to the fire.
