Designation:F107687(Reapproved 2015)1An 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 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.1NOTEKeywords section was editorially added in May 2015.1.Scope1.1 This practice covers expanded welded and silver brazedsocket joints for use 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 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.NOTE1The dimensionless designator nominal pipe size(NPS)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 standard.The values given in parentheses are mathematicalconversions to SI units that are provided for information onlyand are not considered standard.1.6 This standard does not purport to address all of thesafety concerns,if any,associated 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.Referenced Documents2.1 ASTM Standards:2A312/A312M Specification for Seamless,Welded,andHeavily Cold Worked Austenitic Stainless Steel PipesB75 Specification for Seamless Copper TubeB88 Specification for Seamless Copper Water TubeB466/B466M Specification for Seamless Copper-NickelPipe and Tube2.2 Military Standards:3MIL-P-1144 Pipe,Corrosion-Resistant,Stainless Steel,Seamless and WeldedMIL-T-16420 Tube,Copper-Nickel Alloy,Seamless andWeldedMIL-T-24107 Tube,Copper(Seamless)2.3 ASME Standard:4ASME Boiler Code2.4 Federal Standard:3Title 46 Code of Federal Regulations2.5 NAVSEA Document:30900-LP-001-7000 Fabrication and Inspection of BrazedPiping Systems3.Significance and Use3.1 Expanded welded socket joints may be used with thefollowing pipe and tube:3.1.1 Seamless Copper Tube2.375-in.(60-mm)outsidediameter through 6.625-in.(170-mm)outside diameter.3.1.2 Seamless Copper-Nickel Tube2.375-in.(60-mm)outside diameter through 6.625-in.(170-mm)outside diameter.3.1.3 Seamless Copper Water Tube2.125-in.(55-mm)out-side diameter through 4.125-in.(105-mm)outside diameter.3.1.4 Seamless Stainless Steel Pipe2 NPS through 6 NPS,Schedules 5 and 10.3.2 Expanded silver brazed socket joints may be used withthe following tube:3.2.1 Seamless Copper Tube2.375-in.(60-mm)outsidediameter through 6.625-in.(170-mm)outside diameter.1This practice is under the jurisdiction of ASTM Committee F25 on Ships andMarine Technology and is the direct responsibility of Subcommittee F25.11 onMachinery and Piping Systems.Current edition approved May 1,2015.Published June 2015.Originallyapproved in 1987.Last previous edition approved in 2010 as F1076 87(2010).DOI:10.1520/F1076-87R15.2For referenced ASTM standards,visit the ASTM website,www.astm.org,orcontact ASTM Customer Service at serviceastm.org.For Annual Book of ASTMStandards volume information,refer to the standards Document Summary page onthe ASTM website.3Available from U.S.Government Printing Office Superintendent of Documents,732 N.Capitol St.,NW,Mail Stop:SDE,Washington,DC 20401,http:/www.access.gpo.gov.4Available from American Society of Mechanical Engineers(ASME),ASMEInternational Headquarters,Two Park Ave.,New York,NY 10016-5990,http:/www.asme.org.Copyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United States1 3.2.2 Seamless Copper-Nickel Tube2.375-in.(60-mm)outside diameter through 6.625-in.(170-mm)outside diameter.3.2.3 Seamless Copper Water Tube2.125-in.(55-mm)out-side diameter through 4.125-in.(105-mm)outside diameter.3.3 Expanded welded and silver brazed socket joints may beused where experience or test has demonstrated that the joint issafe and suitable for design and operating conditions,andwhere adequate provision is made to prevent separation of thejoint.4.Materials and Manufacture4.1 Welded Socket Joint:4.1.1 Seamless Copper TubeSpecification B75,UNSNumber C12200 and MIL-T-24107,UNS Number C12200,light drawn(see 5.3).4.1.2 Seamless Copper-Nickel Tube(90-10)SpecificationB466/B466M,UNS Number C70600 and MIL-T-16420,UNSNumber C70600,Class 200,annealed.4.1.3 Seamless Copper-Nickel Tube(70-30)SpecificationB46
