ASTM A178 Electric Resistance Welded Carbon Steel and Carbon Manganese Steel Boiler and Superheater Tubes
Material: Carbon steel and carbon manganese steel
Production: Electric Resistance Welding
Size range: O.D.: 12.7-127mm W.T.:0.9-9.1mm L: according to customer
requirement
Applications: For Boilers, Superheaters, Heat-Exchangers, Condensers, Boiler flues, Superheater flues and Safe ends
Heat treatment:
After welding, all tubes are heat treated at a temperature of 1650℉
(900℃) or higher and followed by cooling in air or in the cooling
chamber of a controlled atmosphere furnace.
Cold-Drawn tubes are heat treated after the final cold-draw pass at
a temperature of 1200℉(650℃)or higher.
