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.
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.
- The pipes of this unification are supplied, unless specifically requested otherwise when ordering, in commercial lengths from 4 to 8 m.
- external diameter: ± 1% ± 0,5mm
the higher of the two values
- of the thickness:
- for Øe ≤ 219.1 mm ± 12,5%
0 ± 0.4 mm, the higher of the two values
for Øe> 219.1 mm
± 20% when the Sp/Øe ratio is ≤ 0.025
± 15% when the Sp/Øe ratio is> 0.025
Hydraulic test at 70 bar or equivalent test with Non Destructive Controls of an electromagnetic type (Eddy Current)
Unless otherwise requested with the order, test report 2.2 is released according to norm EN 10204
Normally the pipes are supplied raw, without any surface protection
Smooth, cut perpendicularly to the pipe's axis
The application range of the pipes of this unification is limited to piping and constructions without any special requirements.
