Organization: ASTM International
Publication Date: 1 March 2018
Status: inactive
Page Count: 6
ICS Code (Iron and steel pipes): 23.040.10
scope:

1.1 This specification2 covers carbon and alloy steel pipe, electric-fusion-welded with filler metal added, fabricated from pressure-vessel-quality plate of several analyses and strength levels and suitable for high-pressure service at high temperatures. Heat treatment may or may not be required to attain the desired mechanical properties or to comply with applicable code requirements. Supplementary requirements are provided for use when additional testing or examination is desired.

1.2 The specification nominally covers pipe 16 in. [400 mm] in outside diameter and larger with wall thicknesses up to 3 in. [75 mm] inclusive. Pipe having other dimensions may be furnished provided it complies with all other requirements of this specification.

1.3 Several grades and classes of pipe are provided.

1.3.1 Grade designates the type of plate used as listed in Table 1.

(A) Hardness values listed are applicable to S3.(B) Grade 91 shall be designated by Type 1 or Type 2 when required by the prevalent specification.

1.3.2 Class designates the type of heat treatment performed in the manufacture of the pipe, whether the weld is radiographically examined, and whether the pipe has been pressure tested as listed in 1.3.3.

1.3.3 Class designations are as follows (Note 1):

Class Heat Treatment on Pipe Radiography, see Section Pressure Test, see Section
       
10 none none none
11 none 9 none
12 none 9 8.3
13 none none 8.3
20 stress relieved, see 5.3.1 none none
21 stress relieved, see 5.3.1 9 none
22 stress relieved, see 5.3.1 9 8.3
23 stress relieved, see 5.3.1 none 8.3
30 normalized, see 5.3.2 none none
31 normalized, see 5.3.2 9 none
32 normalized, see 5.3.2 9 8.3
33 normalized, see 5.3.2 none 8.3
40 normalized and tempered, see 5.3.3 none none
41 normalized and tempered, see 5.3.3 9 none
42 normalized and tempered, see 5.3.3 9 8.3
43 normalized and tempered, see 5.3.3 none 8.3
50 quenched and tempered, see 5.3.4 none none
51 quenched and tempered, see 5.3.4 9 none
52 quenched and tempered, see 5.3.4 9 8.3
53 quenched and tempered, see 5.3.4 none 8.3

Note 1: Selection of materials should be made with attention to temperature of service. For such guidance, Specification A20/A20M may be consulted.

1.4 Optional requirements of a supplementary nature are provided, calling for additional tests and control of repair welding, when desired.

1.5 The values stated in either SI units or inch-pound units are to be regarded separately as standard. Within the text, the SI units are shown in brackets. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard. The inch-pound units shall apply unless the "M" designation of this specification is specified in the order.

1.6 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
