Hoesch Schwerter Extruded Profiles GmbH develops special steel profiles in close collaboration with individual users or branches of industry. Every profile solves a special construction or manufacturing problem.
In particular, components for thermal processing plants are required to meet diverse structural demands. Together with the minimum tensile requirement, these consist of defined resistance to oxidation, corrosion and abrasive wear.
For this application as well as for other cases where a thermal-corrosive load is present, the plant designers have taken a path to equip the classical boiler pipe â with its existing inherent strength in normal atmospheres â”; with a âcoatingâ? of highly corrosion resistant austenitic material.
As a result of this composition of materials, closely bonded together, a tube is made whose carbon steel element withstands typical thermo-mechanical demands whilst the austenitic materials take care of corrosion resistance.
The tubes are manufactured by the hot extrusion process, a process which also permits the production of complex geometries using metals which are usually difficult to form.
Hoesch Schwerter Extruded Profiles GmbH belongs to the Italian group Calvi Holding SpA/Calvi Network.
