Boiler tubes are used in: Fire-tube boiler, a type of boiler in which hot gases from a fire pass through one or more tubes running through a sealed container of water. Water-tube boiler, a type of boiler in which water circulates in tubes heated externally by hot gases from a fire. This disambiguation page lists articles associated with the title Boiler tube.
Heavy wall boiler tube is bent to various radii. Boiler tubes (not pipe) are sized according to OD and minimum wall thickness prior to bending. Boiler tubes can be quite long and heavy making material handling a large part of the overall production concerns. Boiler tubes are often ganged together and follow parallel paths through the boiler with a minimum spacing between the tubes.
Superheater tubes and reheater tubes in a comprehensive range of stainless steels and nickel alloys for a wide range of boiler applications.Superheater tubes and reheater tubes in a comprehensive range of stainless steels and nickel alloys covering outside diameters 12 to 260 mm (0.472 to 10.24 in.).
The fire-tube boilers covered a steam production range of 1-20 t/hr at pressures from 10 to 20 bar. Fuels include heavy fuel oil (HFO), Sasol gas, paraffin and coal. The survey covers a total of 85 fire-tube boilers inspected over a four year period (1998-2001).
Enter the wall thickness and the OD (outside diameter) to calculate the weight per foot of round boiler tubing. Weights vary depending on the actual wall thickness from the tube manufacturer.
Calculate the minimum required wall thickness of a water tube boiler 2.75 in O.D., strength welded (E, or, e = 0) into place in a boiler. The tube has an average wall temperature of 650°F. The Maximum Allowable Working Pressure (MAWP) is 580 psi gauge.
A shell or flued boiler is an early and relatively simple form of boiler used to make steam, usually for the purpose of driving a steam engine. The design marked a transitional stage in boiler development, between the early haystack boilers and the later multi-tube fire-tube boilers. A flued boiler is characterized by a large cylindrical boiler shell forming a tank of water, traversed by one or more large flues …
Tube OD surfaces experience thermal fatigue stress cycles which can occur from normal shedding of slag, sootblowing, or from cyclic operation of the boiler. Thermal cycling, in addition to subjecting the material to cyclic stress, can initiate cracking of the less elastic external tube scales and expose the tube base material to repeated corrosion.
Many manufacturers used variants of the vertical cross-tube boiler, including Atkinson, Clayton, Garrett and Sentinel. Other types include the Clarkson 'thimble tube' and the Foden O-type wagon's pistol-shaped boiler. Steam fire-engine makers such as Merryweather usually used water-tube boilers for their rapid steam-raising capacity.
