1、Designation: F1076 87 (Reapproved 2010)An American National StandardStandard Practice forExpanded Welded and Silver Brazed Socket Joints for Pipeand Tube1This standard is issued under the fixed designation F1076; the number immediately following the designation indicates the year oforiginal adoption

2、 or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.1. Scope1.1 This practice covers expanded welded and silver brazedsocket joints for use

3、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 in

4、 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 (NPS)

5、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, associated w

6、ith 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.

(1.5 mm)(expanded welded socket joint, Fig. 1) a

34、nd18 in. (3 mm)(expanded silver-brazed joint, Fig. 2) between the end of thepipe/tube and the bottom of the socket by bottoming thepipe/tube and backing off slightly before tacking.5.9 The minimum insertion length shall be 1 in. (25 mm).5.10 For United States Navy Application (see NAVSEADocument 090

35、0-LP-001-7000), on the pipe/tube inserted intothe expanded joint make a light scribe line a distance of 2 in.(50 mm) from the end of the unexpanded pipe/tube. This scribeline shall be visible at the time of final inspection.5.11 The filler metal used in brazing shall be a nonferrousmetal or alloy ha

36、ving a melting point above 1000F (537C)and below that of the metal being joined.5.12 The brazing material shall have a shearing strength ofat least 10 000 psi (68 950 KPa).6. Dimensions and Tolerances6.1 Dimensions are as indicated in Fig. 1.6.2 The inside diameters of pipe/tube in socket joints mus
