What Does an Equal Union Do?
Joins Matching Pipe Sizes
- Connects two sections of the same PPS pipe OD
- Creates a straight inline pipe connection
- Useful when extending an existing pipe run
- Suitable for main distribution and branch piping
- Maintains a consistent pipe diameter through the connection
Modular PPS Installation
- Designed for the Prevost PPS aluminum piping system
- Supports modular system construction
- Useful for new installations and network expansions
- Allows pipe runs to be modified as facility requirements change
- Provides a purpose-built alternative to improvised pipe connections
Common Applications
Pipe Connections
- Joining two straight pipe sections
- Extending existing PPS pipe runs
- Connecting replacement pipe sections
- Building long main distribution lines
- Creating branch network extensions
Industrial PPS Networks
- Manufacturing facilities
- Machine shops
- Automotive service facilities
- Production areas
- Plant utility distribution
- Compressed air piping installations
Selecting the Correct Union Size
Select the aluminum union according to the outside diameter of the PPS pipe being connected. Because this is an equal union, both pipe sections must use the same outside diameter.
Confirm the pipe OD before ordering and review the published A and B dimensions when installation clearance is limited. Larger pipe sizes require correspondingly larger union bodies.
Installation Considerations
- Confirm the outside diameter of both pipe sections before ordering.
- Use the same union size as the pipe OD being connected.
- Cut PPS pipe square before assembly.
- Deburr and prepare pipe ends according to Prevost installation requirements.
- Keep pipe ends and fitting interiors clean before assembly.
- Fully insert and secure the pipe according to PPS installation procedures.
- Support piping appropriately on both sides of the union.
- Do not exceed the published maximum operating pressure of 232 PSI.
- Maintain the system within the published -4°F to 176°F operating temperature range.
- Pressure-test the completed piping network before normal operation.
- Installation should be completed by personnel familiar with industrial piping systems.
