Product introduction
Internal Thread 90-Degree Elbow
An Internal Thread 90-Degree Elbow is a pipe fitting designed to change the direction of flow by 90 degrees while featuring female (internal) threads on both ends for easy screw-type installation. These elbows are commonly used in low-to-medium pressure piping systems where welding is impractical or disassembly may be required for maintenance.
Key Features & Specifications
1. Design & Construction
- 90° Direction Change: Provides a right-angle turn in piping systems.
- Internal Threads (Female): Allows direct screw-on connection with male-threaded pipes or fittings.
- Materials:
- Carbon steel (ASTM A105)
- Stainless steel (304/316)
- Brass, bronze (for corrosion resistance)
- PVC/CPVC (for chemical/water applications)
- Pressure Rating: Typically Class 150 to Class 3000, depending on material and design.
2. Types & Variations
- Short Radius (SR): Compact design for tight spaces.
- Long Radius (LR): Smoother flow with reduced pressure drop.
- Street Elbow: One male-threaded end and one female-threaded end for direct pipe insertion.
3. Applications
- Plumbing & water supply systems
- Hydraulic & pneumatic systems
- HVAC & refrigeration lines
- Industrial process piping (low-pressure)
- Fire protection & gas distribution systems
4. Advantages
- Easy Installation: No welding required; simply screw onto threaded pipes.
- Removable/Reusable: Ideal for systems requiring maintenance or modifications.
- Leak-Resistant: Proper thread sealing (Teflon tape, pipe dope) ensures tight connections.
- Space-Saving: Compact design fits in confined areas.
5. Limitations
- Not suitable for high-pressure/temperature applications (compared to welded fittings).
- Threads may wear over time with frequent disassembly.
- Requires proper sealing to prevent leaks.
6. Standards & Compliance
- ASME B16.11 (Forged steel threaded fittings)
- ASTM A105/A182 (Material standards)
- MSS SP-83 (Threaded unions & elbows)
7. Installation Tips
- Use thread sealant (Teflon tape or pipe compound) to prevent leaks.
- Avoid over-tightening to prevent thread damage.
- Inspect threads for wear or corrosion before installation.
Why Choose an Internal Thread 90° Elbow?
This fitting is ideal for low-cost, easy-installation systems where frequent disassembly might be needed. Its threaded design eliminates welding, making it versatile for maintenance-heavy environments while ensuring a secure, directional flow change.
