ASME B16 9 Short Radius Pipe Elbow Manufacturer

What is a Short Radius Elbow?

A Short Radius (SR) Elbow is a type of pipe fitting used to change the direction of flow in a piping system, typically by 45° or 90°, within a compact space. The term “short radius” means that the elbow’s curvature radius is equal to the pipe diameter (1D), making it smaller and tighter compared to a long radius elbow. This design is particularly useful in tight or confined areas where space is limited and a sharp turn in the pipeline is required.

Short Radius Elbows are available in seamless, welded, and fabricated types and are manufactured in accordance with international standards like ASME B16.9, ASME B16.28, and MSS-SP-43. They are made from various materials including stainless steel, carbon steel, alloy steel, and duplex/super duplex steel to suit different operating pressures and temperatures. The compact design of SR elbows, while efficient for tight layouts, can cause a slightly higher pressure drop due to the sharper change in flow direction.

Short Radius Elbows are widely used in petrochemical plants, oil & gas refineries, shipbuilding, power generation, and water treatment systems. They are ideal for piping systems where space constraints or specific layout requirements demand tighter bends. SR elbows are also commonly used in high-pressure or low-flow systems where the smooth transition of flow is less critical. Their durable construction, precision fit, and ability to withstand demanding conditions make them suitable for both industrial and commercial applications.
