Alumina-forming bimetallic tubes for refinery furnaces and methods for their preparation and use |
| abstract |
The present invention provides a method for producing a low carbon steel material comprising (i) an outer tube layer formed from carbon steel or low chromium steel comprising less than 15.0 wt.% Cr based on the total weight of the steel; (ii) an inner surface of the outer tube layer of an alumina forming bulk alloy comprising 5.0 to 10.0 wt.% Al, 20.0 to 25.0 wt.% Cr, less than 0.4 wt.% Si, at least 35.0 wt. An inner tube layer formed from the alumina forming bulk alloy by plasma powder welding on the substrate; And (iii) an oxide layer formed on the surface of the inner tube layer, more particularly to a binary metal tube for the transport of hydrocarbon feedstock in a furnace radiation coil. |
