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

 

Material
The ASTM A214 specification covers carbon steel tubes that are welded and used specifically for heat-exchangers and condensers. These tubes are made from carbon steel, which is a widely used material in various industries due to its excellent mechanical properties and affordability.

 

Specification
The ASTM A214 specification sets forth the requirements for welded carbon steel tubes used in heat-exchanger and condenser applications. The specification covers dimensions, tolerances, mechanical properties, and other essential parameters to ensure the quality and performance of the tubes.

 

Chemical Composition
The chemical composition of ASTM A214 carbon steel tubes typically complies with the following requirements:

Element	Composition Range
Carbon	0.10% max
Manganese	0.90% max
Phosphorus	0.035% max
Sulfur	0.035% max

 

Mechanical Properties
ASTM A214 carbon steel tubes are known for their robust mechanical properties, which enable them to withstand high temperatures and pressures in heat-exchanger and condenser applications. The typical mechanical properties include:

Property	Minimum Value
Tensile Strength	325 MPa (47,000 psi) min
Yield Strength	180 MPa (26,000 psi) min
Elongation	35% min
Hardness (HRB)	72 max

 

Steel Grade
ASTM A214 does not specify any particular steel grade. However, the carbon steel tubes usually comply with the grades specified in other relevant ASTM standards, such as ASTM A179 or ASTM A106, based on the required mechanical properties and intended application.

 

Application
ASTM A214 carbon steel welded tubes find widespread usage in heat-exchanger and condenser systems across various industries, including power generation, chemical processing, oil and gas, refrigeration, and HVAC (heating, ventilation, and air conditioning). These tubes provide efficient heat transfer and reliable performance, making them suitable for demanding applications where thermal energy exchange is critical.
