Manufacture
ASTM A214 Heat-Exchanger and Condenser Tubes shall be made by electric-resistance welding.
 

 
Heat Treatment
After welding, all tubes shall be heat treated at a temperature of 1650°F [900°C] or higher and followed by cooling in air or in the 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°F [650°C] or higher.

 
 
Chemical Composition
 
Carbon, max %0.18
Manganese, %0.27 to 0.63
Phosphorus, max, %0.035
Sulfur, max, %0.035

 
Hardness Requirements
The tubes shall have a hardness number not exceeding 72 HRB.

Mechanical property requirements do not apply to tubing smaller than 1 ⁄ 8 in. [3.2 mm] in inside diameter or 0.015 in. [0.4 mm] in thickness.

 

 
Mechanical Tests Required
  • Flattening Test—One flattening test shall be made on specimens from each of two tubes from each lot or fraction thereof.

  • Flange Test—One flange test shall be made on specimens from each of two tubes from each lot  or fraction thereof.

  • Reverse Flattening Test—One reverse flattening test shall be made on a specimen from each 1500 ft [450 m] of finished tubing.

  • Hardness Test—Brinell or Rockwell hardness tests shall be made on specimens from two tubes from each lot.

  • Hydrostatic or Nondestructive Electric Test—Each tube shall be subjected to either the hydrostatic or the nondestructive electric test. The purchaser may specify which test is to be used.
