Heat Exchanger Tube, ASTM A213 T9 Alloy Steel Seamless U Bend Tube For Fired Heaters
ASTM A213 T9 Alloy Steel U Bend Tubes are seamless ferritic alloy steel tubes designed to withstand high temperatures and pressures. They are made of a type of steel which contains small amounts of carbon, manganese, and silicon, as well as large amounts of chromium and molybdenum, to provide excellent resistance to oxidation, corrosion, and deformation at high temperatures. T9 Alloy Steel U Bend Tubes are commonly used in boilers, super heaters, heat exchangers in power plants or other industrial environments.
Benefits:
T9 Alloy Steel U Bend Tubes offer high temperature strength, excellent resistance to corrosion and oxidation, good weldability and formability, and they are cost effective compared to other high-temperature alloys. Thus, they are usually used in high-pressure and high-stress environments such as boilers, heat exchangers & power plants.
