JIS G3454 Carbon Steel Pipe Specification
JIS G3456 carbon steel pipe is a type of steel pipe in Japanese Industrial Standard (JIS), mainly used for high temperature pipelines.
ASTM A179 (SA 179) standard specification covers seamless cold drawn low carbon steel pipe, for tubular heat exchanger, condensers and other similar heat transfer equipment.
The ASTM A179 tube covers the OD from 1/8” to 3”, which is 3.2m m to 76.2 mm. Other diameters and thickness smaller than the specified sizes also applicable to this standard, but mechanical properties is not applicable for the size smaller than 1/8” and 3.2 mm, or thickness smaller than 0.015 inch 0.4 mm.
