Abstract
An expanded metal with an aerodynamic cross-section for use in high velocity fluid flows to decrease pressure drop. The expanded metal has a rhomboid cross-section with the acute angle of oriented into the flow. Also disclosed is a method of making the expanded metal.
Claims8
An expanded metal comprising:
- a single metal sheet slit intermittently at an acute angle to the surface of the metal sheet and stretched forming strands defining apertures and having a rhomboid cross-section oriented such that one acute angle of the rhomboid is positioned furthest from a plane defined by the sheet.
A method of making an aerodynamic expanded metal, said method comprising:
- intermittently slitting a metal sheet at an acute angle to the surface of said metal sheet, then
- stretching said metal sheet to form a series of apertures.
For a catalyst support having expanded metal as the substrate material onto which the other elements of the catalyst are deposited, the expanded metal comprising single metal sheet slit intermittently at an acute angle to the surface of the metal sheet and stretched forming strands defining apertures and having a rhomboid cross-section section oriented such that one acute angle of the rhomboid is positioned furthest from a plane defined by the sheet.
