A galvanized steel elbow is a pipe fitting used to change the direction of piping systems, typically at 45° or 90° angles. Made from carbon steel, it undergoes a galvanization process where a protective zinc coating is applied to prevent rust and corrosion. This makes it ideal for outdoor, industrial, and plumbing applications where moisture resistance is crucial.
**
Key Features:**
**
Durability** - Zinc coating extends lifespan in harsh environments. **
Corrosion Resistance** - Protects against rust, ideal for water and gas lines.
**
Easy Installation** - Threaded or socket-weld options for secure connections.
**
Cost-Effective** - More affordable than stainless steel but still robust.
*
Common Uses:*
- **Plumbing systems** (water supply, drainage)
- **HVAC ductwork**
- **Industrial piping** (chemical, oil & gas)
- **Agricultural and construction applications**
Galvanized steel elbows come in various sizes (1/2" to 12"+) and schedules (SCH 40, SCH 80). They can be bevel-ended** (for welding). While durable, they shouldn't be used with acidic or highly corrosive fluids, as zinc can degrade over time.
For long-term reliability in wet or outdoor conditions, galvanized steel elbows are a practical, budget-friendly choice.

1. **Long Radius (LR) vs Short Radius (SR)**
- **LR Elbow**: Radius = 1.5×Pipe Diameter (e.g., DN100 LR elbow R=150mm). Lower pressure drop.
- **SR Elbow**: Radius = 1×Pipe Diameter. Compact but higher turbulence.
2. **Special Types**
- **Mitered Elbow**: Fabricated from segments for large diameters (>24").
- **Lined Elbows**: PTFE/PP lined for corrosion resistance.
3. **Selection Guide**
- Choose material based on fluid corrosivity, temperature, and pressure.
- Stainless steel elbows may require solution annealing (e.g., 304/316L).
