Product Description
Carbon steel pipe is the most common use piping material in different industries served for construction, structural, liquid transmissions for water, oil and gas. Typical carbon steel pipe material grades in API 5L Grade B, X42 to X70, ASTM A106 B, ASTM A53 B, ASTM A252 Grade 3 and ASTM A333 Grade 6 etc.

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/ ASME SA179 Heat Exchanger Carbon Seamless Steel Pipe 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.
Features of ASTM A179/ ASME SA179 Heat Exchanger 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.
