ASME SB338 Seamless Gr7 Titanium Alloy Heat Exchanger Tubes
YUHONG Group offers ASTM B338 / ASME SB338 Gr7 SMLS Titanium alloy steel tubes and we sell these tubes in more than 70 countries up to now. This specification covers the requirements of titanium and titanium alloy tubing intended for surface condensers, evaporators, and heat exchangers. Grade 7-- Unalloyed titanium plus 0.12 to 0.25 % palladium
Titanium and titanium alloy tubes are new structural materials. Due to titanium has the advantages of high melting point, high strength, good toughness, fatigue resistance, acid and alkali corrosion resistance, low thermal conductivity, and good high and low temperature resistance, it is widely used in chemical heat exchange equipment. In general, titanium tubes have been widely used in seawater desalination, petroleum, chemical industry, mechanical equipment, nuclear power equipment and other fields, and playing a huge and important role.
