ASME B16.9 Elbow
Carbon Steel 45 Degree Elbow Manufacturers, ANSI B16.9 Long Radius Elbow Dimensions
ASME B16.9 Elbow belongs to a range of pipe fittings that have a diameter of ½ inches through 48 inches. Pipe fittings are products that are used to connect pieces of pipes or piping components together without compromising the integrity of the whole piping. Dinesh Industries is a manufacturer and supplier of different pipe fittings. There are bends, couplings, elbows and so on. The ASME 16.9 elbow dimensions make it applicable with small to medium size range of piping applications. There are different grades of materials used in the production of the fittings as well. The elbows come in different types, shapes and sizes as well.

The B16.9 long radius elbow has a longer bending radius than normal. This helps the elbow to eliminate the sudden pressure changes on the inside during the directional change. The short radius elbow on the other hand is the usual product. The 3d elbow has a radius that is 3 times the outer diameter of the pipe whereas the 5 d elbow has a radius 5 times bigger than the outer diameter of the pipe. The carbon steel 45 degree elbow and the SS 90 degree elbow ASME b16.9 are the commonly used ones, but there is also the 180 degree elbow.
