What is ASTM A179/ ASME SA179 ?

Low-carbon steel continuous, minimal wall thickness tubing for condensers, heat exchanger tubes, as well as other heat transfer applications are covered by STM A179. Seamless, cold-drawn low-carbon alloy steel pipe is covered by the ASTM A179 (SA 179) required specifications.

For SA179 heat exchanger tubes, the minimum yield strength is 26 Ksi 180 Mpa, the minimum tensile strength is 47 Ksi 325 Mpa, as well as the minimum stretch is 2 inches or 50 millimeters (about 1.97 in) at 35%.

The elemental composition is as follows: Mn (Manganese) 0.27-0.63 percent, P (Phosphorus) max. 0.035 percent, S (Sulfur) 0.035 percent, and C (Carbon) 0.06-0.18 percent. The ASTM A179 Heat Exchanger Tube is a robust, flexible tubing with long-bearing capabilities.

What is the OD of ASTM A179 Seamless Boiler Tubes?

The OD range of the SA 179 seamless carbon cold-drawn steel tubes is 1/8″ to 3″, or 3.2mm (about 0.13 in) to 76.2mm (about 3 in). However, mechanical qualities are not relevant for sizes down to 1/8″ & 3.2 mm (about 0.13 in), or widths less than 0.015 inches and 0.4 mm (about 0.02 in). Other diameters & widths smaller than the mentioned specifications are also relevant to this standard.

ASTM A179 Heat Exchanger Tubes, Hot Rolled as well as Cold Drawn, Seamless, 1/4″ NB – 2″ NB (Nominal Bore Size) 1 mm (about 0.04 in) to 8 mm (about 0.31 in) in width, outside diameter Width, lengths of up to 27000mm (about 88.58 ft) in maximum length with plain ends, beveled ends, or coupling, etc.

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 Seamless Boiler Tubes

1. 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.
2. 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].
3. 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.

ASTM A179 Seamless Boiler Tubes and its usage

ASTM A179 Seamless Boiler 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 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 Seamless Boiler Tubes

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.
