ASTM B338 Gr7 Seamless and Welded Titanium Alloy Tubes for Condenser Heat Exchanger
YUHONG GROUP deal with stainless steel seamless pipe and tube already more than 33 years, every year sell more than 80000 tons of stainless steel seamless pipe and tube. Our client already cover more than 65 countries. Our stainless steel seamless pipe and tube was width used in Mining, Energy, Petrochemical, Chemical Industry, Food plant, Paper plant, Gas and Fluid Industry etc.
Description
Grade 7 titanium tube is mechanically and physically the same as CP 2 grade titanium, but due to the addition of palladium to Grade 7 titanium, it is the most corrosion-resistant of all titanium alloys.
Grade 7 titanium tubes are widely used in heat exchange equipment such as tubular heat exchangers, coil heat exchangers, serpentine tube heat exchangers,condensing evaporators and transport piping. Many nuclear power industries use Grade 7 titanium tubes as standard tubes for their equipment.
