Internal thread 90 degree Reducing elbow
Product Detail
Standard
Product introduction
Internal Thread 90° Reducing Elbow
1. Product Definition
A 90-degree reducing elbow with internal threads is a specialized pipe fitting designed to:
Change flow direction by 90°
Transition between different pipe sizes
Provide female (internal) threaded connections at both ends
2. Key Specifications
Connection Type:
Internal NPT/BSPT threads at both inlet and outlet
Tapered threads conforming to ASME B1.20.1
Reduction Ratio:
Standard step-down sizes (e.g., 1"×3/4", 2"×1-1/2")
Custom ratios available (max 2:1 reduction)
Materials:
Carbon steel (ASTM A105)
Stainless steel (A182 F304/316L)
Brass/bronze (for water service)
Forged construction per ASME B16.11
3. Design Features
Concentric Reduction: Smooth internal transition for minimal turbulenc
Reinforced Shoulder: Extra material at reduction point for strength
Full Thread Depth: Ensures proper engagement with male pipes
Hex Flats: Wrenching surfaces for easy installation
4. Performance Advantages
✔ Space Saving: Eliminates need for separate reducer + elbow
✔ Leak Resistance: Single-piece design reduces potential leak paths
✔ Flow Optimization: Gradual diameter change minimizes pressure drop
✔ Installation Efficiency: 50% faster than welded alternatives
5. Installation Guidelines
Thread Preparation:
Clean threads with appropriate brush
Apply thread sealant (PTFE tape for NPT, Loctite 567 for BSPT)
Assembly:
Hand-tighten both connections (minimum 3 full turns)
Final torque: 1/4 to 1/2 turn past hand-tight
Alignment Check:
Verify proper flow direction before pressurization
Support piping to prevent thread strain
6. Quality Assurance
100% thread gauge inspection
Hydrostatic tested to 1.5x rated pressure
Material certification per ASTM/ASME requirements
Surface inspection per MSS SP-55
7. Industry Applications
Water Treatment: Pipe size transitions in filter systems
HVAC: Refrigerant line directional changes
Industrial Plumbing: Chemical process lines
Oil & Gas: Instrumentation connections
8. Standards Compliance
ASME B16.11: Forged fittings standard
ASTM A105/A182: Material specifications
MSS SP-114: Corrosion-resistant requirements
NACE MR0175: For sour service applications
Note: For systems with vibration, recommend using:
Thread locking compounds (e.g., Loctite 242)
Secondary mechanical locking devices
