(Specification)Standard Specification for Aluminum and Aluminum-Alloy Seamless Pipe and Seamless Extruded Tube for Gas and Oil Transmission and Distribution Piping Systems
Standard Specification for Aluminum and Aluminum-Alloy Seamless Pipe and Seamless Extruded Tube for Gas and Oil Transmission and Distribution Piping Systems
SCOPE
1.1 This specification covers seamless pipe and seamless extruded tube in the aluminum and aluminum alloys (Note 1) and tempers listed in Tables 2 and 3, respectively. Seamless pipe and seamless tube are intended for use in applications involving internal pressure. Note 1-Throughout this specification use of the term alloy in the general sense includes aluminum as well as aluminum alloy. Note 2-For drawn seamless tubes, see Specification B210; for extruded tubes, Specification B221; for drawn seamless tubes for condensers and heat exchangers, Specification B234; for seamless pipe and seamless extruded tube, B241/B241M; for round welded tubes, Specification B313; for seamless condenser and heat exchanger tubes with integral fins, Specification B 404; for extruded structural pipe and tube, Specification B429; and for drawn tube for general purpose applications, Specification B483.
1.2 Alloy and temper designations are in accordance with ANSI H35.1. The equivalent Unified Numbering System alloy designations are those of Table 1 preceded by A9, for example, A93003 for aluminum alloy 3003 in accordance with Practice E527.
1.3 For acceptance criteria for inclusion of new aluminum and aluminum alloys in this specification, see Annex A2.
1.4 A complete metric counterpart to Specification B345 has been developed (B345M); therefore, no metric equivalents are presented in this specification.

A
The basis of establishment of mechanical property limits is given in Annex A1 of this specification.
B
To determine conformance to this specification, each value for ultimate tensile strength and for yield strength shall be rounded to the nearest 0.1 ksi [MPa] and each
value for elongation to the nearest 0.5 %, both in accordance with the rounding method of Practice E 29.

Elongation of full-section and sheet-type specimens is measured in 2 in.; of cut-out round specimens, in 43 specimen diameter.
D
For material of such dimensions that a standard test specimen cannot be taken, or for material thinner than 0.062 in., the test for elongation is not required.
E
Elongations in 50 mm apply for tube tested in full section and for sheet-type specimens machined from material up through 12.5 mm in thickness having parallel
surfaces. Elongations in 53 diameter (5.65 A ), where D and A are diameter and cross-sectional area of the specimen, respectively, apply to round test specimens

F
These alloys are also produced in the F temper, for which no mechanical properties are specified.
G
Maximum tensile strength and minimum elongation apply to tubes having diameters from 1.000 in. to 4.500 in. and wall thickness from 0.050 in. to 0.169 in. only.

H
Upon heat treatment, annealed (0 temper) material shall be capable of developing the mechanical properties applicable to T42 temper material, and upon solution and

I
Yield strength is maximum [110 MPa] max.
J
For stress-relieved tempers (T4510, T4511, T6510 and T6511) characteristics and properties other than those specified may differ somewhat from the corresponding
characteristics and properties of material in the basic temper.
