Buttweld Long & Short Radius 90° Elbow | ASME/ANSI B16.9, B16.28, MSS-SP-43
A 90-degree elbow is a crucial pipe fitting designed to change the direction of a piping system by 90 degrees. Widely used in various industries, these elbows are essential for creating turns in piping systems while maintaining flow efficiency and system integrity. They are available in different materials such as stainless steel, carbon steel, and alloy steel, making them versatile for use in diverse applications.
A Short Radius (SR) 90-Degree Elbow features a compact design with a centerline radius equal to the pipe's diameter, making it ideal for tight spaces where minimal bending radius is required. In contrast, a Long Radius (LR) 90-Degree Elbow has a larger centerline radius, 1.5 times the pipe's diameter, offering smoother flow and reduced pressure loss, making it suitable for systems prioritizing efficiency and minimal turbulence.
Ample Alloys, specialize in providing durable and precision-engineered 90° Pipe Elbows that meet international standards such as ANSI B16.9 and ASME B16.9. These elbows are designed for smooth directional changes in pipelines, ensuring minimal pressure drop and efficient flow management. Whether for high-pressure systems or corrosive environments, our elbows deliver consistent performance.
