§ 56.60-1 Acceptable materials and specifications (replaces 123 and Table 126.1 in ANSI-B31.1).
(a)(1) The material requirements in this subpart shall be followed in lieu of those in 123 in ANSI-B31.1.
(2) Materials used in piping systems must be selected from the specifications which appear in Table 56.60–1(a) of this section or Table 56.60–2(a) of this part, or they may be selected from the material specifications of section I, III, or VIII of the ASME Code if not prohibited by a regulation of this subchapter dealing with the particular section of the ASME Code. Table 56.60–1(a) of this section contains only pipe, tubing, and fitting specifications. Determination of acceptability of plate, forgings, bolting, nuts, and castings may be made by reference to the ASME Code as previously described. Additionally, accepted materials for use as piping system components appear in Table 56.60–2(a) of this part. Materials conforming to specifications not described in this subparagraph must receive the specific approval of the Marine Safety Center before being used. Materials listed in Table 126.1 of ANSI B31.1 are not accepted unless specifically permitted by this paragraph.
(b) Components made in accordance with the commercial standards listed in Table 56.60–1(b) of this section and made of materials complying with paragraph (a) this section may be used in piping systems within the limitations of the standards and within any further limitations specified in this subchapter.
Table 56.60-1(a)_Adopted Specifications and StandardsNote: Table 56.60-1(A) replaces Table 126.1 in ANSI B31.1 and sets forthspecifications of pipes, tubing, and fittings intended for use in piping- systems. The first column lists acceptable standards from ASTM; the second lists those from ANSI. The Coast Guard will consider use of alternative pipes, tubing, and fittings when it receives certification of their mechanical properties. Without this certification it will restrict use of such alternatives to piping-systems inside heat exchangers that ensure containment of the material inside pressure shells.------------------------------------------------------------------------ ------------------------------------------------------------------------Pipe, seamless: A106 Carbon steel............
