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. 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.
