ASTM A333 alloy pipes

ASTM A333 Specification for Seamless and Welded Steel Pipe for Low-Temperature Service. Our products for ASTM A335 alloy steel pipes have been listed as follows:

ASTM A333 Gr.9

ASTM A333 Gr.10

ASME SA333 Gr.6

ASTM A333 Grade 4

ASTM A333 Grade 3

ASTM A333 Grade 1

ASTM A333 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.

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”.
