Hot drawn boiler tubes EN 10216-2, EN 10216-4 and cold drawn EN 10305-1
or unalloyed steel, with properties specified for specific operating conditions.
Special characteristics
Steel boiler pipe EN 10216-2, round section, produced by hot rolling. Available in a wide range of diameters and wall thicknesses.
Boiler tube EN 10305-1, also round manufactured by cold forming. It is produced in a no smaller size range, which makes it possible to easily select a product, with the necessary data, to solve certain problems.
Given the special operating conditions, the boiler pipe is endowed with considerable strength, resistance to significant temperatures and high pressure, as well as good resistance to corrosive influences.
Applications
The price of boiler room pipes is fully justified by its high performance properties. The product is successfully used in the formation of pipelines operating under high pressure and high temperatures, the manufacture of steam boilers, boiler plants, ship equipment.
