A179 Boiler Tube/ Cold Drawn Boiler Tube

ASTM A179 Standard specification covers standards for electric-resistance-welded tubes with minimum-wall-thickness made of carbon steel and carbon-manganese steel to be used in boiler tubes, boiler flues, superheater flues, and safe ends. The steel shall be of Grades A (low-carbon steel), C (medium-carbon steel), or D (carbon-manganese steel). All tubes shall be submitted to heat treatment after welding, followed by cooling. The steel shall conform to stated compositions of carbon, manganese, phosphorus, sulphur, and silicon. Grades C and D shall conform to given tensile requirements, that is tensile strength, yield strength, and elongation. The material shall also be subjected to flattening, flange, tension, reverse flattening, and hydrostatic (or nondestructive electric) tests. Crush test shall also be performed if asked by the purchaser. Minimum elongation values are also given.

 

 

 

 

 

 

 

 

ASTM A179 Cold Drawn Boiler Tube Features-

 

Low-temperature services serve at -45F°F (-45°C) Excellent strength and ductility.
Conductivity than alloy steels.
Higher strength with low coefficients of thermal.
Better weldability and greater toughness.
