ASTM A214 Carbon Steel Welded Tube For Heat-Exchanger and Condenser

ASTM A214 is a standard specification for carbon steel welded tubes used in heat exchangers and condensers. This specification covers minimum wall thickness welded tubes made from carbon steel and intended for use in boiler, superheater, and Heat Exchanger Tubes.

Material and Specification

ASTM A214 specifies the requirements for welded carbon steel tubes for use in heat exchangers and condensers. The tubes shall be made by the electric-resistance-welding process and shall be furnished in the following conditions:

Size Range: 1/2 to 5 in. [12.7 to 127 mm]
Wall Thickness: 0.035 to 0.320 in. [0.9 to 8.1 mm]
Length: Single Random, Double Random, or Cut Length
End Finish: Plain End, Beveled End, Threaded

Chemical Composition

The chemical composition of ASTM A214 carbon steel welded tubes is specified as follows:

Element	Composition, %
Carbon	0.18 max
Manganese	0.27 to 0.63
Phosphorus	0.035 max
Sulfur	0.035 max
Silicon	0.10 min

Mechanical Properties

The mechanical properties of ASTM A214 carbon steel welded tubes are specified as follows:

Property	Value
Tensile Strength, min, psi [MPa]	60,000 [415]
Yield Strength, min, psi [MPa]	37,000 [255]
Elongation in 2 in. or 50 mm, min, %	30

Steel Grade

ASTM A214 carbon steel welded tubes are available in two grades:

Grade A: Maximum carbon content of 0.18%.
Grade C: Maximum carbon content of 0.35%.

Application

ASTM A214 carbon steel welded tubes are primarily used in heat exchangers and condensers for conveying gases and liquids. These tubes are used in a wide range of industrial applications, including power generation, chemical processing, and petrochemical refining.
