STAINLESS STEEL FITTINGS 180° SR ELBOW ASTM A403 B16.9 USED FOR PIPING SYSTEMS
A 180° SR Elbow (Short Radius) is primarily used to redirect fluid flow by 180 degrees in tight spaces where a compact piping layout is required.

Applications:
Heat Exchangers: Used to redirect flow in serpentine heat exchanger
designs.
Hydronic Systems: Helps create loops in heating or cooling systems.
Industrial Piping: Used to save space by avoiding additional
routing for reverse flow.
Plumbing Systems: Utilized in drainage or water supply systems
where a reverse bend is necessary.

Example Scenarios
- A hydronic heating system uses a 180° SR elbow to loop heated water back to the boiler in a basement with limited vertical space.
- A chemical processing plant installs SR elbows to route pipes around large reactors without expanding the facility.
- In shipbuilding, these elbows fit piping into narrow corridors between bulkheads and machinery.
Why Choose a 180° SR Elbow?
- Space Savings: Radius = 1× pipe diameter (e.g., 2-inch pipe → 2-inch radius).
- Cost-Effective: Often cheaper than LR elbows due to less material.
- Efficiency in Tight Spots: Enables complex routing in congested areas.
