Seamless Condenser Tube A179,Seamless Nickel alloy Tube B163

Seamless Condenser Tube A179, ASTM A179 Heat Exchanger Tubes

ASTM A179/A179M, ASME SA179/SA179M is the standard applicable to Seamless cold drawn low carbon steel heat exchanger and condenser tubes.

When we place a specific order for SA 179 tubing, we should include below material specifications:

Standard and the name of material: ASTM A179 / ASME SA 179 seamless tubes.

Manufacturing types in cold drawn

Size including Diameters and minimum wall thickness

The factory actual scene of ASTM A179 tubes

ASTM A179 seamless tubes are widely used in industries such as petroleum, chemical, medical, food, light industry, machinery, instrument, include industrial pipeline and mechanical structure parts, etc.

What is a heat exchanger used for?

A heat exchanger is a device designed to efficiently transfer or "exchange" heat from one matter to another. When a fluid is used to transfer heat, the fluid could be a liquid, such as water or oil, or could be moving air. The most well known type of heat exchanger is a car radiator.

ASTM A179 covers minimum-wall thickness, seamless cold-drawn low-carbon steel tubes for tubular heat 

exchangers, condensers, and similar heat transfer apparatus. Tubes shall be made by the seamless process and shall be cold drawn. Heat and product analysis shall be performed wherein steel materials shall conform to required chemical compositions of carbon, manganese, phosphorus, and sulfur. The steel materials shall also undergo hardness test, flattening test, flaring test, flange test, and hydrostatic test.


ASTM A179  is a brief summary of the referenced standard. It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application. ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date.


ASTM A179 covers minimum-wall-thickness, seamless cold-drawn low-carbon steel tubes for tubular heat exchangers, condensers, and similar heat transfer apparatus.


ASTM A179 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.

Ordering Information: It shall be the responsibility of the purchaser to specify all Requirements that are necessary for products under this specification. Such requirements to be considered included,but are not limited to,the following:

Quantity ( feet, meters, or number of lengths )

Name of material ( seamless tubes )
