1、Designation: F 1076 87 (Reapproved 2004)An American National StandardStandard Practice forExpanded Welded and Silver Brazed Socket Joints for Pipeand Tube1This standard is issued under the fixed designation F 1076; the number immediately following the designation indicates the year oforiginal adopti
2、on or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon (e) indicates an editorial change since the last revision or reapproval.1. Scope1.1 This practice covers expanded welded and silver brazedsocket joints for u
3、se on shipboard piping systems.1.2 Expanded welded and silver brazed socket joints are tobe used to join two pipes or tubes having the same NPS (seeNote 1) without using a fitting or butt weld.1.3 Brazed socket type joints are not intended for use onsystems containing flammable or combustible fluids
4、 in areaswhere fire hazards exist or where the service temperatureexceeds 425F (205C).1.4 Brazed joints depending solely upon a fillet weld ratherthan primarily upon brazing material between pipe/tube andsocket are not covered by this practice.NOTE 1The dimensionless designator nominal pipe size (NP
5、S) hasbeen substituted in this practice for such traditional terms as “nominaldiameter,” “size,” “nominal size,” and “iron pipe size.”1.5 The values stated in inch-pound units are to be regardedas the standard.1.6 This standard does not purport to address all of thesafety concerns, if any, associate
6、d with its use. It is theresponsibility of the user of this standard to establish appro-priate safety and health practices and determine the applica-bility of regulatory limitations prior to use.2.
