ASTM F1076-87(2010)

Standard Practice for Expanded Welded and Silver Brazed Socket Joints for Pipe and Tube

SIGNIFICANCE AND USE
Expanded welded socket joints may be used with the following pipe and tube:  
Seamless Copper Tube—2.375-in. (60-mm) outside diameter through 6.625-in. (170-mm) outside diameter.  
Seamless Copper-Nickel Tube—2.375-in. (60-mm) outside diameter through 6.625-in. (170-mm) outside diameter.  
Seamless Copper Water Tube—2.125-in. (55-mm) outside diameter through 4.125-in. (105-mm) outside diameter.  
Seamless Stainless Steel Pipe—2 NPS through 6 NPS, Schedules 5 and 10.  
Expanded silver brazed socket joints may be used with the following tube:  
Seamless Copper Tube—2.375-in. (60-mm) outside diameter through 6.625-in. (170-mm) outside diameter.  
Seamless Copper-Nickel Tube—2.375-in. (60-mm) outside diameter through 6.625-in. (170-mm) outside diameter.  
Seamless Copper Water Tube—2.125-in. (55-mm) outside diameter through 4.125-in. (105-mm) outside diameter.  
Expanded welded and silver brazed socket joints may be used where experience or test has demonstrated that the joint is safe and suitable for design and operating conditions, and where adequate provision is made to prevent separation of the joint.
SCOPE
1.1 This practice covers expanded welded and silver brazed socket joints for use on shipboard piping systems.  
1.2 Expanded welded and silver brazed socket joints are to be used to join two pipes or tubes having the same NPS (see Note 1) without using a fitting or butt weld.  
1.3 Brazed socket type joints are not intended for use on systems containing flammable or combustible fluids in areas where fire hazards exist or where the service temperature exceeds 425°F (205°C).  
1.4 Brazed joints depending solely upon a fillet weld rather than primarily upon brazing material between pipe/tube and socket are not covered by this practice.
Note 1—The dimensionless designator nominal pipe size (NPS) has been substituted in this practice for such traditional terms as “nominal diameter,” “size,” “nominal size,” and “iron pipe size.”  
1.5 The values stated in inch-pound units are to be regarded as the standard.  
1.6 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.
