ASME SA179 Mild Steel Pipe is steel pipe and alloy pipe that meets specific standards, including minimum wall thickness, seamless cold drawing, and low carbon content. Widely used in heat transfer equipment, condensers and similar tools, it can withstand high pressure and high temperature working environments.
According to the ASME SA179 seamless steel pipe standard, pipes or tubes with minimum wall thickness, seamless cold drawing and low carbon content can be used as heat transfer equipment, condensers and heating temperatures. It covers steel pipes with outer diameters from 1/8 to 3. Pipe smaller than this size or with a wall thickness less than 0.015 inches is not allowed.
What is ASME SA 179 (ASTM A179) Standard Specification.?
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 3.2mm to 76.2mm.

To ensure that pipes meet the required standards, they 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 pipe must also comply with the applicable provisions of the current edition of Specification A 450/A 450M.
ASTM A179 pipe is available in different sizes and wall thicknesses and is also available in U-bends.
