ASTM B338 Gr.2 Titanium tubes are typically used in commercial heat exchangers
The Titanium Seamless Tube is much smoother and has less absolute roughness. The seamless pipes can be used in precise applications such as equipment and instrumentation. The pipes come under different dimensions based on ASTM, ASME and API standards. Out of all the grades of titanium, grade 5 is the most used. The Grade 2 Titanium Tubing is a commercially pure grade.
Titanium Pipe and Seamless Tubes are made up of different grades of titanium alloys. There are commercially pure grades of titanium and alloyed grades. Navstar Steel is a leading manufacturer and supplier of Titanium Pipe in different grades and dimensions. The specifications for the titanium pipes are ASTM B337 and ASTM B338. Titanium is naturally strong and corrosion-resistant. The titanium oxide which forms on the surface avoids further oxidation.
Titanium tube widely used in electrical equipment, salt-making equipment, ocean anti-corrosion, petroleum drilling equipment, heat exchanger, condenser, heater distiller, evaporator
Titanium Grade 1 Pipes & Tubes are the gentlest titanium having the mix of specific traits like most elevated pliability, great cool formability and a superb resistance from mild to high oxidization. These Titanium Grade 1 Pipes & Tubes are shown as seamless pipes & welded pipes.
