What is ASTM A179?

ASTM A179 is a standard specification for seamless cold-drawn low-carbon steel tubes used in tubular heat exchangers, condensers, and similar applications.

The ASTM A179 tubes are produced through a cold-drawing process, which helps to improve their dimensional accuracy and surface finish.

Scope of ASTM A179/A179M

ASTM A179 /ASME SA179 covers minimum-wall-thickness, seamless cold-drawn low-carbon steel tubes for tubular heat exchangers, condensers, and similar heat transfer apparatus.
ASTM A179 /ASME SA179 covers tubes 1/8 to 3 in. [3.2 to 76.2 mm], inclusive, in outside diameter. Note 1Tubing smaller in outside diameter and having a thinner wall than indicated in this specification is available. Mechanical property requirements do not apply to tubing smaller than 1/8 in. [3.2 mm] in outside diameter or with a wall thickness under 0.015 in. [0.4 mm].
The values stated in either inch-pound units or SI units are to be regarded separately as standard. Within the text, the SI units are shown in brackets. The values stated in each system are not exact equivalents; therefore, each system must be used independently of the other. Combining values from the two systems may result in nonconformance with the specification. The inch-pound units shall apply unless the “M” designation of this specification is specified in the order.

What is ASTM A179 tube material?

ASTM A179 covers minimum-wall thickness, seamless cold-drawn low-carbon steel tubes for tubular, heat exchanger, condensers, and other heat transfer services. seamless ASTM A 179 steel tube is supplied and produced by cold drawning method. Chemical composition contains carbon, manganese, phosphorus, and sulfur.

Features of ASTM A179/A179M

ASTMA179/ASME SA179 standard is applicable for steel pipes together with outside diameter of 1/8in-3in. (32 mm to 76.2 mm). Our rolling technology has reached the international advanced spot. JST is able to manufacture cold drawn seamless steel tubes with uniform wall depth. Their tolerance is relatively smaller standard your own.

When seamless carbon steel pipes are during the last cold drawing procedure, they will enter micro oxidization and non-oxidation heat treatment furnace for thermal treatment (Temperature is 1200℉ (650℃) if not more.). This makes the surface of cold drawn seamless steel tubes match the no oxide scale standards, and guarantees smooth surface and stable performance.

JST adopts professional hardness testing equipment to find out the hardness of seamless carbon steel pipes. The Rockwell hardness value not able to exceed 72 HRB.

Top rated program customers' requirements, we can analyze the cold drawn seamless steel tube advertise its chemical composition meet standards. We choose one from 250 pipes or select one in a furnace to investigate. If the product analysis fails, then choose another two seamless carbon steel pipes. All elements of two steel pipes tend to be in accordance with standards, and then these pipes can be delivered.

Note:

Mill test certificates will be issued according to EN10204.3
All tubes shall be supplied as per applicable ASTM Specification.
The tubes Shall be Seamless and the testing shall be as per A 450 / A450M.
