ASME/ANSI B16.9, ANSI B16.28, MSS-SP-43 Buttweld 180° Elbow Manufacturer
A 180-degree elbow is used in piping systems to change the direction of flow by 180 degrees, enabling a full reversal of the flow path. It is commonly used in applications where pipes need to redirect in a completely opposite direction. 180-degree elbows are available in various materials, including stainless steel, carbon steel, alloy steel, nickel alloys, and monel. The material selection depends on factors like temperature, pressure, and the fluid being transported.
180 degree Short Radius (SR) elbows have a bend radius equal to the pipe diameter. They are ideal for tight spaces but can create more friction, resulting in higher pressure loss. 180 deg Long Radius (LR) elbows have a bend radius 1.5 times the pipe diameter, providing smoother flow and reducing pressure loss, making them suitable for most standard applications.
Ample Alloys is a trusted manufacturer and supplier of high-quality 180-degree elbows, With a commitment to precision and reliability, Ample Alloys provides 180-degree elbows in various schedules such as Schedule 10, Schedule 40, and Schedule 80, suitable for both low and high-pressure applications.
