ASTM A733-2003焊接及无缝碳素钢和奥氏体不锈钢管接头标准规范

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 Steel8212;Pipe nipples ordered under these requirements are intended for general uses, as described by Specification A 53. 1.1.2 Seamless Carbon Steel8212;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 Steel8212;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.

ASTM A795-2000防火用黑色及热浸镀锌的焊接和无缝钢管的标准规范

1.1 This specification covers black and hot-dipped galvanized welded and seamless steel pipe in sizes NPS 1/2 (Note 1) to NPS 10 inclusive, with wall thicknesses as given in Table 1 and Table 2. Pipe having other wall thicknesses may be furnished provided such pipe complies with all other requirements of this specification and the outside diameter is as given in Table 2. Pipe ordered under this specification is intended for use in fire protection systems. The pipe may be bent, but it is not intended for bending made at ambient temperature wherein the inside diameter of the bend is less than twelve times the outside diameter of the pipe being bent (Note 2). Note 1--The dimensionless designator NPS (nominal pipe size) has been substituted in this standard for such traditional terms as "nominal diameter," "size," and "nominal size." Note 2--Successful bending of pipe is a function of equipment and technique as well as pipe properties. 1.2 This pipe is suitable for joining by the following methods: 1.2.1 Light-Weight Fire Protection Pipe-- Rolled groove, welding, and fittings for plain end pipe. See Table 1 for dimensions. 1.2.2 Standard-Weight Fire Protection Pipe-- Cut or rolled groove, threading, welding, and fittings for plain end pipe. See Table 2 for dimensions. 1.2.3 For pipe having dimensions other than those of Table 1 and Table 2, the joining method must be compatible with the pipe dimensions. A complete listing of standard light weight dimensions appears in ASME B36.10 and B36.19. 1.3 The following precautionary caveat pertains only to the test method portion, Sections 8, 9, and 10, of this specification: This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. 1.4 The values stated in inch-pound units are to be regarded as the standard. The SI equivalents may be approximate.
