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.

Standard Specification for Seamless and Welded Steel Pipe for
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
Scope of ASTM A333
- This specification covers nominal (average) wall seamless and
welded carbon and alloy steel pipe intended for use at low
temperatures. Several grades of ferritic steel are included as
listed in Table 1. Some product sizes may not be available under
this specification because heavier wall thicknesses have an adverse
affect on low-temperature impact properties.
- Supplementary Requirement S1 of an optional nature is provided.
This shall apply only when specified by the purchaser.
- The values stated in either inch-pound units or SI units are to be
regarded separately as standard. Within the text, the SI units are
shown in brackets. The values stated in each system are not exact
equivalents; therefore, each system must be used independently of
the other. Combining values from the two systems may result in
nonconformance with the specification. The inch-pound units shall
apply unless the “M” designation of this specification is specified
in the order.
- Note 1: The dimensionless designator NPS (nominal pipe size) has
been substituted in this standard for such traditional terms as
“nominal diameter”, “size”, and “nominal size”.
