ASTM A333 Seamless Low Temperature Steel Pipe

ASTM A333 is the standard specification given to all the welded as well as seamless steel, carbon and alloy pipes which are intended to be used at places of low temperatures. The ASTM A333 pipes are used as heat exchanger pipes and pressure vessel pipes.

 Product introduction 

ASTM A333 is the standard specification given to all the welded as well as seamless steel, carbon and alloy pipes which are intended to be used at places of low temperatures. The ASTM A333 pipes are used as heat exchanger pipes and pressure vessel pipes.
As it was stated in the above section, that these pipes are used in the areas where temperature is extremely low, they are used in large ice cream industries, chemical industries and other such places. They are used as transportation pipes and are categorized into different grades. The classification of grades of these pipes is done on different factors like temperature resistance, tensile strength, yielding strength and chemical compositions. The ASTM A333 pipes are furnished into nine different grades which are designated by the following numbers:1,3,4,6.7,8,9,10, and 11.

These pipes have an NPS 2"to 36". Though different grades have different temperature strike test the average temperature that these pipes can stand is from-45 degree C, to-195 degree C. The ASTM A333 pipes must be made with the seamless or welding process where there must be no filler in the metal during the welding process.
ASTM A333 standard covers wall seamless and welded carbon and alloy steel pipe intended for use at low temperatures. 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. Tensile tests, impact tests, hydrostatic tests, and nondestructive electric tests shall be made in accordance to specified requirements. Some product sizes may not be available under this specification because heavier wall thicknesses have an adverse affect on low-temperature impact properties.
ASTM A333 steel pipe production includes a series of visual surface imperfections to guarantee that they have been properly manufactured. ASTM A333 steel pipe shall be subject to rejection if surface imperfections acceptable are not scattered, but appear over a large area in excess of what is considered a workmanlike finish. The finished pipe shall be reasonably straight.
