ASTM A333 / A333M - 16 Standard Specification for Seamless and Welded Steel Pipe for Low-Temperature Service and Other Applications. ASTM A333 alloy pipe shall be made by the seamless or welding process with the addition of no filler metal in the welding operation. All seamless and welded pipes shall be treated to control their microstructure.
The main purpose of alloy steel pipe is to use in power plants, nuclear power, high-pressure boilers, high-temperature superheaters and reheaters and other high-pressure and high-temperature pipelines and equipment. It is made of high-quality carbon steel, alloy structural steel and stainless heat-resistant steel. , After hot rolling (extrusion, expansion) or cold rolling (drawing). Alloy steel pipe is a kind of seamless steel pipe, its performance is much higher than the general seamless steel pipe, because this steel pipe inside containing Cr, high temperature resistance, low temperature, corrosion-resistant performance of other non-pipe joints not match, so the more extensive use of alloy tube in the petroleum, aerospace, chemical, electric power, boiler, military, and other industries.
A333 pipe is furnished to nine different grades designated by numbers 1, 3, 4, 6, 7, 8, 9, 10, & 11.
