Buttweld Long Radius 45° Elbow Manufacturer, Supplier & Exporter
Valtron Forge & Fittings is a leading manufacturer, supplier, stockist, and exporter of premium quality Buttweld Long Radius 45° Elbow in India. We offer a comprehensive range designed to meet international standards and the demanding requirements of industrial piping systems.
Our long radius 45° elbows provide a gradual 45-degree change in flow direction, minimising pressure drop, turbulence and erosion in critical pipeline systems.
A Long Radius (LR) 45° Elbow has a centre-to-face dimension of 1.5 times the nominal pipe diameter (1.5D). The larger sweep produces smoother flow transition, lower friction losses and reduced wear, making it the standard choice for process and transmission pipelines.
Key Features
1.5D bending radius for smooth, low-friction flow transition
Reduced pressure drop, turbulence and pipe wall erosion
Available in seamless and welded construction
Uniform wall thickness and consistent bore throughout the bend
Bevelled ends as per ASME B16.25 for full-penetration welding
Available in all grades of stainless, carbon, alloy and nickel alloys
Ideal for long-distance transmission and process pipelines
