ASTM A333 GR. 6 22inch Diameter SCH80 Seamless Pipes
ASTM A333 Low Temperature Service Carbon Steel Seamless Pipes
ASTM A333 (ASME S/A-333) Pipe grades permit low temperature service. This specification covers nominal (average) walled pipes including seamless and welded. Several grades of ferritic steel are included. Some product sizes may not be available under this specification because heavier wall thicknesses have an adverse effect on low-temperature impact properties. A333 pipe is furnished to nine different grades designated by numbers 1, 3, 4, 6, 7, 8, 9, 10, & 11.
