Unconventional copper alloys for Oil & Gas and petrochemical
Since 1924, Metalminotti has been a leader in the production of UNCONVENTIONAL COPPER ALLOYS for the Oil & Gas and petrochemical sectors. We are a fully integrated manufacturer with production facilities in Italy equipped with cutting-edge technology. We guarantee the highest quality and precision at every stage of production, serving a global market with custom solutions tailored to meet the needs of our worldwide customers.
PRODUCTS FOR HEAT EXCHANGERS AND CONDENSERS
Metalminotti produces a wide range of customized components for heat exchangers and condensers, in Copper Nickel, Aluminum Bronze, Naval Brass, and OT60:
•Tubesheets and baffles: Key components for heat exchangers, designed to withstand high pressures and ensure maximum reliability.
•Flanges: Made with aluminum bronze and copper-nickel alloys for optimal corrosion resistance.
•Tie rods
•Sand castings: Highly customized products, ideal for applications requiring great precision and structural strength.
These components, made from corrosion-resistant alloys with high thermal conductivity, are ideal for use in petrochemical installations and applications requiring chemical inertia. In the production of tubesheets, we follow an advanced manufacturing process that refines the crystalline structure of the alloys, preventing the formation of porosity. This improves machinability, especially during drilling, which is the most critical stage of the process.
To quickly respond to customer needs, Metalminotti maintains a large stock of sheets. Additionally, thanks to our new CNC water cutting machine for precise cutting to design with millimetric tolerances, we can guarantee precision, speed, and reliability, even for urgent requests.
CASTINGS FOR VALVES AND PUMPS
In addition to components for heat exchangers, Metalminotti specializes in high-quality castings for pumps and valves. Our components include:
•Valves: bodies, stems, seats, covers, discs
•Pumps: bodies, impellers, discs
•Shut-off valves for desalination plants
These castings, made with strong and durable alloys, ensure optimal performance even under challenging operating conditions, providing long service life and high reliability.
NON-SPARKING TOOLS: SAFETY WITHOUT COMPROMISE
Metalminotti also produces a complete range of non-sparking tools, essential for safe operation in explosive environments typical of the Oil & Gas and petrochemical sectors. Made from special alloys, our tools ensure high safety and performance, minimizing the risk of sparks during use. Learn more about our non-sparking tools here.
