· PDF fileBoiler construction is thus largely the science of joining metal plates, tubing, and piping, in required configurations, so the vessel can withstand these pressure differences and stresses. In this module we will examine some of the common methods of construction, such as welding, staying, and tube expanding.

19-06-2010· The construction of watertube boilers, which use small-diameter tubes and have a small drum, enable the generation or production of steam at high temperatures and pressures. The weight of the boiler is much less than an equivalent firetube boiler and the steam raising process is much quicker. Design arrangements are flexible, efficiency is high and the feedwater has a good natural circulation. …

A fire-tube boiler is a type of boiler in which hot gases from a fire pass through one or more tubes running through a sealed container of water. The heat of the gases is transferred through the walls of the tubes by thermal conduction, heating the water and ultimately creating steam..
