ANSI B16.9 Long Radius Elbow

View Stanless Steel LR Elbow Dimensions, Check Long Radius Elbow ASME B16.9 Standard

Stainless Steel Long Radius Elbow is a type of pipe fitting used to connect two pipes together in a stainless steel pipeline. The elbows are of different types. There are 45 degree elbows which change the flow of direction by 45 degrees and the 90 degree elbows that change the flow of direction in 90 degree angle. Rajveer Stainless And Alloys is a manufacturer and supplier of all kinds of elbows. Our Carbon Steel Long Radius Elbow is meant for the connection to be made over a longer distance for the change of flow.

This allows the piping to distribute the pressure over a longer span of the elbow. The Long Radius Elbow Dimensions Inches can vary from ½ inches to 24 inches in diameter and the length varies according to the customization of the application. The 6 90 Degree Elbow Dimensions indicate that the elbow is of NPS 6 and the angle is 90 degrees. The wall thicknesses can vary with the long radius center of the elbow. The Long Radius Elbow ASME B16.9 belongs to the ASME B16.9 specification which governs the diameters of 1/2NPS through 48NPS. We supply all different sizes and dimensions of the SS LR Elbow types. Please contact us for further details and pricing of these elbows.

How to get the center of 45 and 90-degree long radius elbow?

The 45 degree and 90 degree elbows are standard elbows. For non-standard degrees of angle the calculation is done with the length of the elbow, the Tan of the degree of angle and the elbow radius. For a 45 degree elbow and a 90 degree elbow, the center is at the crossing spot of the center lines of both arms. The elbow is one of the commonly used pipe fittings to connect the pipes together while changing the direction of fluid flow. The elbows can cause pressure differences in high pressure lines and the stress and impact have to be taken into consideration when installing elbows.
