ASTM A**3 covers wall seamless and welded carbon and alloy
steel pipe intended for use at low temperatures. The 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.
Scope
1.1 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.
1.2 Supplementary Requirement S1 of an optional nature is provided.
This shall apply only when specified by the purchaser.
1.3 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”.
