WELDED TITANIUM TUBES (VAL-TIMET)

Application

Inland Power Plants

Capper-Nickel Stainless Steel 
For more lhan two decades, Valtimet has supplied welded stainless steel and copper-nickel condenser tubes to inland power generating stations worldwide. Through our long-term relationships with power station engineers and constructors, equipment manufacturers and utilities, we have gained unequalled expertise in manufacturing tubing for nuclear and fossil fuel power plants. Today, because of our advanced welding technologies, extensive product selection, vast experience, and customer commitment, the power generation industry recognizes Valtimet as the world leader in welded tubes.

Nuclear Power Plants

Austenitic and Ferritic Stainless Steel 
For nuclear power generating stations cooled by uncontaminated water ot cooling towers, Valtimet supplies austenitic and ferritic stainless steel welded tubes. Utilities worldwide have switched from copper alloys to these materials to avoid propagation of copper ions in the steam generators and to allow greater circulation speeds.

Saltwater Cooled Power Plants

Titanium 
Valtimet pioneered the manufacture and application of titanium welded tubes for surface condensers to allow power stations to use seawater or brackish river water as the cooling medium. Titanium's unique, naturally occurring oxide film makes it impervious to chloride ion attack. This corrosion immunity, in conjunction with its relatively high thermal conductivity, makes titanium the material of choice for seawater use. Titanium is also specified without a corrosion allowance, resulting in thinner tube walls that increase thermal efficiency and flow rates.

Saltwater corrosion Resistant Tubing

Valtimet's specialty welded tubular products, supported by the sales consortium with Poongsan, satisfy many application requirements for the water purification and desalination industries. Evaporative processes such as multi-stage flash desalination demand tubing that resists saltwater corrosion at elevated temperatures. Valtimet's welded titanium tubes easily meet these criteria. Titanium is impervious to chloride ion attack and permits the inevitable salt buildup in the tubing to be flushed with the sea water. These tubes offer maintenance-free, long life with the advantage of low initial Desalination plant structural cost due to titanium's light weight. For low temperature, low pressure environments, Valtimet's welded copper-nickel or austenitic stainless steel tubes are a cost-effective alternative.

Welded Tubing for Corrosive, High-Temperature Environments

Titanium's resistance to moist chlorine gas and chloride-containing solutions is the basis for a myriad of applications. Titanium is often the beat choice in these environments on a life cycle cost basis because its inherent corrosion resistance prolongs equipment life, reducing maintenance and enhancing plant performance. Valtimet tubing is widely used in chlor-alkali cells, terephthalic acid production, bleaching equipment, heat exchangers, and piping for organic intermediates. We produce titanium tubing in a wide variety of diameters, wall thicknesses and Grades including Ti-Pd, which offers enhanced corrosion resistance to organic acids over traditional, unalloyed Grade 2 titanium. Valtimet also manufactures duplex stainless steel and special grades for industrial processing applications.
