Description

ASTM A178/ SA178 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 e 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.


Tests and Inspection:
