ASTM A179 (SA 179) standard specification covers seamless cold drawn low-carbon steel pipe, for tubular heat exchanger, condensers, and other similar heat transfer equipment.The ASTM A179 tube covers the OD from 1/8” to 3”, which is 3.2m m to 76.2 mm. Other diameters and thicknesses smaller than the specified sizes also apply to this standard, but mechanical properties are not applicable for the size smaller than 1/8” and 3.2 mm, or thicknesses smaller than 0.015 inches 0.4 mm.
ASTM A179 is a steel pipe standard established by the American Society for Testing and Materials (ASTM) and is mainly used in the manufacture of high-pressure equipment such as steam turbines. This kind of steel pipe is made of high-quality carbon steel or alloy steel and is produced through hot rolling or cold drawing processes. It has the advantages of high strength, high pressure resistance, and corrosion resistance.ASTM A179 seamless steel pipe has various specifications. According to different usage occasions and equipment requirements, steel pipes with different diameters and wall thicknesses can be selected. For example, "19.05*2.11" in this example means that the outer diameter of the seamless steel pipe is 19.05 inches and the wall thickness is 2.11 inches.ASTM A179 seamless steel pipes need to go through multiple processes during the manufacturing process, such as billet preparation, rolling, straightening, heat treatment, pickling, inspection, etc. These processes ensure the dimensional accuracy, surface quality, mechanical properties and metallographic structure requirements of the steel pipe.In the manufacturing of high-voltage equipment, ASTM A179 seamless steel pipe plays a very important role. Due to its high strength, high pressure resistance and corrosion resistance, the safety and stability of the equipment can be ensured. For example, in steam turbines, this kind of steel pipe can withstand the erosion and impact of high-temperature and high-pressure steam, ensuring the normal operation of the equipment.In summary, ASTM A179 seamless steel pipe is a high-quality, high-performance steel pipe material that is widely used in the manufacturing of high-voltage equipment. Its advantages of high strength, high pressure resistance and corrosion resistance ensure the safety and stability of the equipment. In fields such as electric power and petrochemical industry, ASTM A179 seamless steel pipe has become one of the indispensable materials.| Speci -cation | Grade | Chemical Composition [%] | ||||||||||||||
