Product 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
