Boiler tubes
Commercial company that distributes from ready
Boiler pipes are smooth pipes made of steel, seamless and in various thicknesses, used in trade for general purposes EN 10216-1:2005 (EX UNI 7287/86) or for the creation of simple pipelines, such as those of the boiler, through which the steam resulting from the boiling heating water flows.
Pipes for thermal uses
Boiler pipes are therefore suitable pipes for supporting the passage of gas at high temperatures, and for this reason they are generally made through cold drawing, which gives the pipe a mechanical compactness of considerable efficiency.
Of course, there are endless variations of boiler pipes, since they can be made with different thicknesses and diameters, as well as with steel equipped with various characteristics depending on the intended use.
