Precision-engineered pipe elbows for efficient directional changes in piping systems
Krishna Forge specializes in manufacturing high-quality pipe elbows designed to change the direction of flow in piping systems. Our elbows are manufactured with precision engineering to ensure optimal fluid dynamics, minimal pressure drop, and long-lasting performance.
Size Range: 1/2" to 48"
Wall Thickness: Schedule 10 to XXS
Types: 45°, 90°, 180°
Radius: Long Radius, Short Radius
Ends: Butt Weld, Socket Weld
Angle Tolerance: ±0.5° to ±1.5°
Comprehensive range of elbow designs for various industrial applications
Used to change direction by 90 degrees. Available in both Long Radius (1.5D) and Short Radius (1D) configurations.
Used for 45-degree directional changes. Provides smoother flow transition with reduced pressure drop.
Used for complete flow reversal. Also known as return bends or U-bends for heat exchangers and boilers.
Combines direction change with pipe size reduction. Available in 90° and 45° configurations with different end sizes.
Fabricated from straight pipe sections cut at specific angles and welded together for large diameter applications.
