Socket Weld Union Configuration
A socket weld union provides a welded connection on each side while incorporating a separable center joint.
The adjoining pipe is inserted into the socket-weld ends and welded in place. The union connection can then be separated when access, maintenance, or piping disassembly is required.
Confirm that the installation specifically requires a union rather than a permanent coupling before fabrication.
ASC S3714U Identification

Construction Details
This fitting uses cast 304 stainless steel construction.
ASC / GetPipe identifies the 304 stainless castings as conforming to ASTM A351 ACI Grade CF8.
The current product information also states that CMTRs are available upon request, that the manufacturing facility is identified as ISO 9001:2008, and that fittings receive independent verification for applicable chemical and mechanical properties.
304 Stainless Steel
This product is the 304 stainless steel version of the ASC 150# cast socket-weld union family.
The 304 stainless casting designation is identified as ASTM A351 ACI Grade CF8.
Confirm compatibility between the fitting material, adjoining pipe, process media, welding procedure, and overall system requirements before installation.
Socket Weld Connections
The union uses socket-weld connections at the piping ends.
The adjoining pipe is inserted into the fitting sockets before the joints are welded in place.
Proper pipe preparation, insertion, alignment, and welding procedures should be followed for the intended piping system.
Why Use a Union?
A union provides a serviceable break point in a piping assembly.
Unlike a standard coupling, the center union connection can be separated after the socket-weld ends have been installed, allowing adjoining sections or equipment to be disconnected without cutting the welded piping.
This can be useful where future maintenance or component removal is anticipated.
Socket Weld Union vs. Full Coupling
Socket Weld Union – S3714U
- Socket-weld connection on each side
- Separable center connection
- Allows piping disassembly
- Useful where future service access is required
- This GetPipe.com product
Socket Weld Full Coupling
- Socket-weld connection on each side
- Permanent one-piece connection
- No separable center joint
- Different installation purpose
- Should not be substituted where a union is required
Socket Weld Union vs. Threaded Union
Socket Weld Union
- Pipe inserts into socket ends
- End connections are welded
- Center union remains serviceable
- Permanent attachment to adjoining pipe
- S3714U configuration
Threaded Union
- Uses threaded end connections
- No socket-weld end joints
- Requires compatible mating threads
- Different installation method
- Should not be substituted without confirming system requirements
SCI Stainless Weld Catalog Reference
The supplied SCI Stainless Weld Fittings Catalog is included as an additional stainless fitting reference.
That catalog states that SCI stainless weld fittings conform to ASTM A403 Grade 304/304L & 316/316L, ASTM A960, and MSS SP-43, with dimensions conforming to ASME B16.9 except wall thickness and MSS SP-43.
Because this product is a cast socket-weld union, use the supplied ASC 150# Stainless Socket Weld document as the more product-specific reference for this fitting.
Pipe Dimensions & Wall Thickness Reference
The supplied GetPipe.com Common Diameters and Wall Thicknesses PDF is included as a general adjoining-pipe reference.
Use it when checking nominal pipe size, outside diameter, and schedule-related wall-thickness information for compatible piping.
The pipe chart should not be interpreted as providing this union's socket depth, overall dimensions, union dimensions, or fitting weight.
Applications
The 150# Cast Stainless Socket Weld Union 304 is intended for compatible piping systems requiring a welded stainless steel connection with a serviceable union joint.
Final suitability should be confirmed against 304 stainless steel material requirements, socket-weld compatibility, adjoining pipe, welding requirements, operating conditions, process media, and the need for future disassembly.
Installation & Selection Considerations
- Confirm that the installation requires a 150#, 304 stainless steel socket-weld union.
- Verify compatibility between both fitting sockets and the adjoining pipe.
- Confirm that a serviceable union connection is appropriate for the piping layout.
- Use appropriate pipe preparation, insertion, alignment, and welding procedures.
- Review the supplied ASC Socket Weld document as the product-specific reference, with the SCI stainless weld catalog and pipe chart used as supporting references.
Use the supplied ASC 150# Stainless Socket Weld document to confirm the S3714U 304 stainless steel, 150#, socket-weld union configuration. The SCI Stainless Weld Fittings catalog and pipe chart are also included as supporting stainless fitting and adjoining-pipe references.

Frequently Asked Questions
What ASC SKU identifies this 304 socket-weld union?
The current GetPipe.com listing identifies the 150# Cast Stainless Socket Weld Union 304 as SKU S3714U.
What material is this fitting?
This product is identified as cast 304 stainless steel.
What ASTM casting grade applies to the 304 version?
ASC / GetPipe identifies the 304 stainless casting as ASTM A351 ACI Grade CF8.
What connection style does this union use?
The fitting uses socket-weld connections at the piping ends.
What is the purpose of a union?
A union provides a separable connection that allows sections of an installed piping system to be disconnected without cutting the adjoining pipe.
How does a socket-weld union work?
The pipe ends are inserted into the union sockets and welded in place, while the center union connection remains separable.
How is a union different from a full coupling?
A full coupling creates a permanent one-piece connection between two pipe ends, while a union provides a center connection that can be separated later.
Is this a threaded union?
No. This product uses socket-weld piping connections rather than threaded end connections.
Does ASC provide CMTRs?
The current GetPipe.com product information states that CMTRs are available upon request.
Are size and dimensional tables included on this page?
No. Size, part-number, packing, weight, and dimensional tables are not included unless specifically requested.
Which supplied PDF is the most product-specific?
The ASC 150# Stainless Socket Weld PDF is the most product-specific supplied document for this cast socket-weld union.
What is the SCI Stainless Weld Fittings Catalog used for here?
It is included as an additional stainless fitting reference. Its primary product family is stainless butt-weld fittings rather than this cast socket-weld union.
What does the Pipe Dimensions and Wall Thickness PDF provide?
It provides general adjoining-pipe reference information for nominal pipe size, outside diameter, and schedule-related wall thickness.
What should I verify before installation?
Confirm 304 stainless material, 150# configuration, socket-weld compatibility, adjoining pipe, union orientation, and the appropriate welding procedure.
Where can I verify the product-specific information?
Use the supplied ASC 150# Stainless Socket Weld PDF linked in Willy's help box directly above this FAQ section.
