How Are Boiler Tubes Made?
As a general rule, boiler tubes are constructed from steel (or steel alloys), or more traditionally from wrought iron.
A live steam version of a boiler may also use copper or brass, since it is cheaper to manufacture smaller boiler tubes out of copper or brass.
The general definition of a boiler is a closed device that heats a fluid inside it (usually water) by passing heat through the fluid.
I would like to point out that there are two main types of boiler tubes: water-tube boiler tubes, and fire-tube boiler tubes.
Fuel is burned within the furnace to produce hot gas which, when combined with water in the tubes in order to produce steam, is able to heat the water inside the tubes in order to produce heat.
Water-tube Boiler tubes
Due to the thermal conduction of the gases through the walls of the tubes, the heat of the gases is transmitted through the water, which in turn heats up the water and eventually produces steam as a result of the process.
Fire-tube Boiler tubes
A boiler tube is a metal tube that is located inside a boiler and is used to heat water to produce steam by passing it through these tubes.
