Form: 90° Long Radius Elbow
A 90° Long Radius Elbow is usually constructed from materials such as stainless steel, alloy steel, carbon steel, or nickel alloys, tailored to meet specific application needs. The long radius design, which measures 1.5 times the pipe diameter, allows for smoother flow and reduces friction, erosion, and pressure drop compared to short radius elbows. These elbows boast impressive mechanical strength, toughness, and resistance to corrosion, temperature, and stress. Their sturdy composition ensures they can withstand high-pressure and high-temperature environments while delivering long-lasting performance.
