Standard Specification for Welded and Seamless Carbon Steel and Austenitic Stainless Steel Pipe Nipples
The following bibliographic material is provided to assist you with your purchasing decision:
This specification covers welded and seamless carbon steel and austenitic stainless steel pipe nipples. The mechanical requirements stated that, pipe nipples shall be made from new, hydrostatic tested or NDE-tested pipe, pipe and nipples shall be threaded on both ends with NPT taper pipe threads. The standard and special lengths and sizes of nipples are presented. Galvanized nipples ordered under this specification shall be made from pipe coated on the inside and outside by the hot dip process. Samples of nipples sufficient to determine their conformance with the requirements of this specification shall be taken at random for each lot of nipples of the same pipe size, length, and material, also, samples shall be inspected to determine their conformance with the dimensional requirements, including thread dimensions.
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.
