Federal Steel offers a full range of low temperature pipe for a wide range of industries and enviornments.

We carry sizes ranging from 1/2" to 36" in seamless and STD through 4" wall thickness. Grades 1 and 6.

ASTM A333 Low Temperature Pipe Specifications

ASTM A333 (ASME S/A-333) Pipe grades permit low temperature service. This specification covers nominal (average) walled pipe almost exclusively in seamless. 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.

  • Sizes range from 1/2" to 36" in seamless
  • STD through 4" wall thickness
  • Grades 1 & 6
