ASME SA179 Low Carbon Steel Pipes
GNEE is a manufacturer specializing in the production of A179 pipes, which are usually manufactured using a seamless cold-drawn process and are made of low-carbon steel, which has good formability, weldability and corrosion resistance.
And available in ASME SA179 heat exchanger tube ODs from 1/8 to 3 inches, or 3.2 to 76.2 mm. For SA179 high temperature pipe, the minimum yield strength is 26 Ksi 180 MPa, the minimum tensile strength is 47 Ksi 325 MPa, and the minimum stretch is 2 inches or 50 mm (approximately 1.97 inches).
In addition, A179 condenser tubes are also provided, which are widely used in air conditioning and refrigeration systems, tube and tube heat exchangers, condensers and other heat transfer equipment.

ASTM A179 round carbon steel tubing
GNEE A179 material tube inspection
To ensure that pipes meet the required standards, pipes are subjected to a number of tests such as product analysis, hardness, mechanical, flattening, flaring, hydrostatic or non-destructive testing, depending on the customer's testing requirements.
The piping must also comply with the applicable provisions of the current edition of Specification A 450/A 450M.ASTM A179 pipes are available in different sizes and wall thicknesses as well as U-bends and finned tubes.
