Download PDFSA179 tubes are specified by ASTM A179/A179M for seamless cold-drawn low-carbon steel heat-exchanger and condenser tubes. They are renowned for their minimum-wall-thickness and are ideal for applications requiring high thermal conductivity and the ability to withstand high pressure and temperature [^1^].
SA179 tubing boasts exceptional thermal conductivity up to 360°C, an elongation rate of up to 30%, and can endure high pressures and temperatures up to 450°F. The low carbon content enhances its strength, durability, and corrosion resistance, making it a preferred choice for various industrial applications [^2^].
When we place a specific order for SA 179 tubing, we should include below material specifications:
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.
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.
The ASTM A179/A179M specification covers tubes from 1/8 to 3 inches in outside diameter. The tubes are manufactured to strict industry standards to ensure consistency in quality and performance. The chemical composition includes carbon (0.06-0.18%), manganese (0.27-0.63%), phosphorus (max 0.035%), and sulfur (max 0.035%) [^3^].
SA179 tubing offers high thermal conductivity, corrosion resistance, and durability. Its smooth surface finish aids in efficient heat transfer, and it is lightweight, making it easy to transport and install [^2^].
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.
ASTM A179 are widely used in industries such as petroleum, chemical, medical, food, light industry, machinery, instrument, include industrial pipeline and mechanical structure parts, etc.
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.
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.
