Federal Steel offers a full range of low temperature pipe for a wide range of industries and enviornments.
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 Grades 3 and 1/6.
