What Is an SP112 Threaded Union?
The Charman Inc SP112 threaded union is a stainless steel fitting designed to join compatible threaded piping while providing a connection that can later be separated. Unlike a conventional coupling, the union can be disconnected at its center connection without cutting the surrounding pipe.
This serviceable design makes a union useful near equipment, valves, piping components, and other locations where future removal or maintenance may be required.
Why Choose a 304 Stainless Steel SP112 Union?
304 Stainless Steel Construction
- Provides good general corrosion resistance
- Suitable for many industrial and commercial environments
- Durable construction for threaded piping systems
- Useful where stainless steel piping components are specified
- Well suited for process, utility, mechanical, and equipment applications
Serviceable Union Connection
- Provides a removable piping connection
- Allows connected sections to be separated without cutting pipe
- Useful near equipment requiring future service
- Supports maintenance and replacement applications
- No welding required for threaded assembly
Common Applications
Industrial & Process Piping
- Process piping systems
- Industrial utility piping
- Equipment connections
- Threaded stainless steel assemblies
- Maintenance piping
Commercial & Mechanical Systems
- Commercial plumbing
- Mechanical piping systems
- Valve connections
- Equipment assemblies
- Maintenance and repair installations
Union vs. Coupling
A standard threaded coupling joins two compatible threaded piping components but does not provide the same convenient mechanical separation point as a union. Removing piping connected by a standard coupling may require additional disassembly of the piping system.
A union is specifically useful where the connection may need to be separated for equipment service, component replacement, maintenance, or future piping modifications.
Where an SP112 Threaded Union Makes Sense
- Creating a removable connection in a threaded piping run
- Connecting serviceable equipment
- Installing valves that may require future removal
- Building threaded stainless steel assemblies
- Providing access for maintenance and repair
- Connecting replaceable piping components
- Industrial process and utility piping
- Mechanical and commercial piping systems
- Retrofit and piping modification projects
Ask Willy: Need Stainless Steel Fitting Information?
Review the Charman Inc stainless steel fittings specification sheet for product and dimensional information on SP112 threaded fittings, or use the complete stainless steel fittings catalog to compare available fitting styles, configurations, and sizes before ordering.
Installation & Selection Guidance
- Confirm the required nominal pipe size before ordering.
- Confirm that the threaded union configuration is appropriate for the piping layout.
- Confirm that 304 stainless steel is compatible with the intended service.
- Inspect fitting and mating threads for damage or contamination before assembly.
- Keep the union's mating surfaces clean during installation.
- Use a thread-sealing method appropriate for the system media, pressure, temperature, and application.
- Begin threaded assembly carefully to reduce the risk of cross-threading.
- Tighten threaded connections using appropriate tools and accepted threaded-piping practices.
- Avoid excessive tightening that could damage the union or mating threads.
- Align the union halves correctly before tightening the center connection.
- Support connected piping to avoid excessive mechanical loading on the fitting.
- Confirm system pressure and temperature requirements before installation.
- Pressure-test completed piping assemblies where required.
- Installation should be completed by qualified personnel and in accordance with applicable codes and specifications.
Product Selection Considerations
Nominal Pipe Size
Select the SP112 union based on the nominal pipe size required for the threaded piping system. Available options range from 1/8" through 2-1/2".
Service Access
Choose a union where a piping connection may need to be separated later for maintenance, equipment removal, valve replacement, repair, or system modification.
