ASTM A179 (ASME SA179) Boiler tubes,Cold Drawn Seamless Carbon Steel Tube

/ / Published in Pipes

Boiler tubes refers to hollow round section steel that is used in manufacturing heat transfer unite, ASTM A179/ASME SA179 specification is designed as American standard of Seamless Cold-Drawn Low-Carbon Steel Heat-Exchanger and Condenser Tubes. Diameter and wall thickness of ASTM A179/ASME SA179 has a wide range from small diameter to several meters. ASTM A179 Steel Tube can be used for pipeline in thermal equipment, industrial machinery, petroleum geological exploration, container, chemical industry and other special purpose.

ASTM A179 steel tube is seamless pipe, it has very strict requirements on steel hardness, surface smoothness, etc. If you are looking for the equivalent foreign standard, you need to focus on its physical properties and test data first. ASTM A179 has higher temperature requirement than ASTM A178. No matter what steel material is, mechanical properties is the key indicator for you to make the final decision, also tensile properties-tensile strength, yield strength, elongation and hardness, temperature performance shall be looked up and put into consideration.

    What is the difference between steel Pipe and Tube?

      Tube is measured by outside diameter, the pipe is measured by inside diameter.
      the actual physical OD of a tube is just the same as it’s nominal OD. The size of a tube will keep the same OD no matter what the wall thickness is.
      For example: The actual outside diameter of 1¼″ pipe is 1.625″ – while 1¼″ tube has a true 1.25″ outside diameter.
      Consequently, both the size of tube and pipe is measured by it’s OD and the thickness.
