DIN17861 3.7035/Gr.2 Titanium and Titanium Alloy tubes for condensers and Heat Exchangers
Application:: Power plants, heat exchanger, condenser, chemical industry, aerospace, titanium structure parts and fasteners for modern industry, marine engineering, petrochemical, oil and gas industry etc.
Titanium tubes are typically used in commercial heat exchangers
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 showed as seamless pipes & welded pipes.
