ASTM A733-01

Standard Specification for Welded and Seamless Carbon Steel and Austenitic Stainless Steel Pipe Nipples

SCOPE
1.1 This specification covers the requirements for welded and seamless carbon steel pipe nipples, black and zinc-coated (hot-dip galvanized), and welded and seamless austenitic stainless steel pipe nipples in standard steel pipe sizes from 1/8to 12 in. inclusive, in standard or special lengths.
1.1.1 Welded Carbon Steel—Pipe nipples ordered under these requirements are intended for general uses, as described by Specification A 53.
1.1.2 Seamless Carbon Steel—Pipe nipples ordered under these requirements are intended for general and special uses, as described by the applicable Specifications A 53 and A 106 ( see 4.1.1).
1.1.3 Austenitic Stainless Steel—Pipe nipples ordered under these requirements are intended for high-temperature and general corrosion service, as described by Specification A 312 (see 4.1.2).
1.1.4 The text for this specification contains notes and/or footnotes that provide explanatory material. Such notes and footnotes, excluding those in tables, do not contain any mandatory language.
