(a)(1) The material requirements in this subpart shall be followed in lieu of those in 123 in ASME B31.1 (incorporated by reference; see 46 CFR 56.01-2).
(1) The material requirements in this subpart shall be followed in lieu of those in 123 in ASME B31.1 (incorporated by reference; see 46 CFR 56.01-2).
(2) Materials used in piping systems must be selected from the specifications that appear in Table 56.60-1(a) of this section or 46 CFR 56.60-2, Table 56.60-2(a), or they may be selected from the material specifications of sections I or VIII of the ASME Boiler and Pressure Vessel Code (both incorporated by reference; see 46 CFR 56.01-2) if not prohibited by a regulation of this subchapter dealing with the particular section of the ASME Boiler and Pressure Vessel 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 Boiler and Pressure Vessel Code as previously described. Additionally, accepted materials for use as piping system components appear in 46 CFR 56.60-2, Table 56.60-2(a). 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 ASME 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.
Note: Table 56.60-1(a) replaces Table 126.1 in ASME B31.1 and sets forth specifications of pipes, tubing, and fittings intended for use in piping-systems. The first column lists acceptable standards from ASTM (all incorporated by reference; see 46 CFR 56.01-2); the second lists those from ASME (all incorporated by reference; see 46 CFR 56.01-2). 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.

needed portion of the required marking is deleted because of size or
is absent because of age of existing stocks.\4\ Because this standard offers the option of several materials, some
of which are not generally acceptable to the Coast Guard, compliance
with the standard does not necessarily indicate compliance with these

as necessary to fully identify the materials. The materials must
comply with the requirements in this subchapter governing the
particular application. [USCG-2003-16630, 73 FR 65179, Oct. 31, 2008]
