ASME B16.9 Elbow can range in diameters ½ inches through 48 inches. The standard ASME B16.9 covers all types of buttweld fittings that range from ½ inches to 48 inches in nominal diameter. R.C. Metal Corporation is a leading manufacturer and supplier of the ANSI B16.9 90 Deg LR Elbows as well as other types of fittings in this standard. The 90 degrees elbows is the most common among elbows. There are different types such as the 45 Degree Short Radius Elbow. It has shorter radius and 45 degrees angle. There are long radius elbows as well. The Carbon Steel 45 Degree Elbow Dimensions vary according to the diameter of the pipe line and the bending radius of the elbows. The bending radius is represented by the D in the marking.
The 5d long radius elbow has a bending radius 5 times that of the pipe’s nominal diameter. The difference in bending radius helps the transition of the turn of angle to be smooth. The 90 degree 3d elbows has a 90 degree angle and a radius 3 times that of the pipe diameter. This helps the fluids or gases to gradually excerpt pressure on the walls rather than suddenly. The Stainless steel 5d elbow is used in applications that have longer pipe lines with high pressure flows such as in the petroleum industries. The low pressure and gaseous applications can use the ASME B16.9 Short radius elbow which has shorter radius.
There are different pressure ratings of the elbows as well. The pressure ratings are governed by schedules. The Long Radius Elbow Sch 40 has a medium schedule of 40 and the pressure capacity is medium with a long radius. There are low pressure and high pressure elbows with different variations such as the Schedule 10 short radius elbow. The short radius and long radius of the elbow could be marked as SS or LS respectively. For example, the 45 Degree SR Elbow is a short radius elbow with 45 degree angle of turn. The most used ones are of standard radius and 90 degrees angle and are known as 1d 90 elbow. Please contact us for more information on the products and pricings.
