ASME Alloy Steel Pipe refers to alloy steel pipes that conform to the standards set by the American Society of Mechanical Engineers (ASME). ASME standards for alloy steel pipes cover aspects such as dimensions, material composition, manufacturing processes, and testing requirements.Alloy steel pipes offer improved strength, hardness, and resistance to wear, corrosion, and high temperatures compared to carbon steel pipes.
