Product Description
product name:
ASTM A214 Carbon Steel For Boilers,Superheaters,Heat-Exchangers, Condensers Electric
Applications: for Boilers,Superheaters,Heat-Exchangers, Condensers
Size range: O.D.:6-76mm W.T.:0.9-19.0mm L: according to customer requirement
Manufacture:
Tubes are made by electric-resistance welding.
Surface Condition:
The finished tubes are free of scale., slight amount of oxidation is not considered as scale
Heat treatment:
After welding, all tubes are heat treated at a temperature of 1200℉(650℃) or higher and following by cooling in air or in a cooling chamber of a controlled atmosphere furnace.
Cold drawn tubes shall be heat treated after the final cold-draw pass at a temperature of 1200℉(650℃) or higher
