Product Description

Product Description

ASME SA179 Seamless Pipe

ASME SA179 Standard covers minimum-wall thickness, seamless cold-drawn low-carbon steel tubes for tubular heat exchangers, condensers, and similar heat transfer apparatus.

ASME SA179 Tubes shall be made by the seamless process and shall be cold drawn. ASME SA179 Tubes shall be heat treated after the final cold drawn pass at a temperature of 1200°F [650°C] or higher.
 
ASME SA179 Tubes should do Product Analysis test, Hardness test, Mechanical Test, Flattening Test, Flaring Test, Hydrostatic Test or NDT Test if agreed by Client.
ASME SA179 Tubes Shall conform to the applicable requirements of the current edition of Specification A 450/A 450M, unless otherwise provided herein.

Applications:

ASME SA179 seamless cold-drawn low-carbon steel tubes for tubular heat exchangers, condensers, and similar heat transfer apparatus.

Mechanical Tests Required
(1)Flattening Test-One flattening test shall be made on specimens from each of two tubes from each lot or fraction thereof.
(2)Flaring Test-One flaring test shall be made on speci- mens from each of two tubes from each lot  or fraction thereof.
(3) Flange Test-When specified as a substitute for the flaring test, for tubes having a wall thickness (actual mean wall) less than 10 % of the outside diameter, one test shall be made on specimens from each of two tubes
(4)Hardness Test-Rockwell hardness tests shall be made on specimens from two tubes from each lot.
(5) Hydrostatic Test-Each tube shall be subjected to the hydrostatic test, or a nondestructive electric test
 

Surface Condition
Finished tubes shall be free of scale. A slight amount of oxidation will not be considered as scale.
