In the fabrication process of tube plates for heat exchangers, Metalminotti follows a special manufacturing cycle which conferes distinctive qualities to alloys, refining their crystalline structure and avoiding any porosity. This allows a superior machining, especially during drilling operations, which are the most critical phases in tube sheets manufacturing.

Metalminotti manufactures the following products as rough and/or finished machined items:

  • Tube plates
  • Baffles
  • Flanges
  • Tie Rods
  • Distributors
  • Floating heads
  • Return end covers, …

made out of alloys resistant to corrosion with high thermal conductivity. These products are widely employed in heat exchangers, condensers of conventional and nuclear power plants, condensators of petrochemical refineries, refrigerators and all applications requiring the chemical inertia of brasses and alu-bronzes.

Metalminotti has a large inventory of sheets in several sizes and ASTM alloys. Moreover, thanks to a new CNC water-jet machine, Metalminotti carries out specific cuttings to get finished items saving material and extra machining.

METALMINOTTI is an ISO 9001 and PED (Pressure Equipment Directive) qualified company.
