ASTM A234 WPB B16.9 L/R Carbon Steel Butt Welding 90 Degree Elbow
Carbon Steel Pipe Fittings Elbow could be a most common sort of CS fitting utilized to connect pipe or tubing to permit a alter of direction, more often than not a 90° or 45° angle, though 22.5 Degree Elbow Carbon Steel is additionally utilized in a piping framework. Carbon steel elbows are metal fittings that change the direction of the pipe on the carbon steel pipe. Connections are threaded and welded. Divided by angle, there are 45 ° and 90 ° 180 ° the three most commonly used, in addition to other engineering needs also include 60 ° and other abnormal angle elbow. Elbow materials are cast iron, stainless steel, alloy steel, malleable iron, carbon steel, non-ferrous metals and plastics. The connections to the tube are: direct welding (the most common method) flange connection, hot melt connection, electrofusion connection, screw connection and socket connection. According to the production process can be divided into: welding elbow, stamping elbow, pushing elbow, casting elbow and so on. Carbon steel elbow is a kind of carbon steel pipe fittings.
Carbon steel elbow is first divided into its radius of curvature, which can be divided into long radius elbows and short radius elbows. The long-radius elbow refers to its radius of curvature equal to 1.5 times the outer diameter of the tube, ie R = 1.5D. A short-radius elbow means that its radius of curvature is equal to the outer diameter of the tube, ie R = 1.0D. (D is the diameter of the elbow, and R is the radius of curvature. D can also be expressed in terms of folds.) If there are 17 levels depending on the pressure rating, the same standards as in the U.S. tube are: Sch5s, Sch10s, Sch10 , Sch20, Sch30, Sch40s, STD, Sch40, Sch60, Sch80s, XS; Sch80, Sch100, Sch120, Sch140, Sch160, XXS, the most commonly used are STD and XS. According to the angle of the elbow, there are 45° elbows, 90° elbows and 180° elbows.

ASME B16.9 L/R Elbow Dimensions
The ASME B16.9 elbow is used when a pipe changes direction. Elbows can turn up, turn down, turn left, right, or any angle in between. The long radius (L/R) elbows denote elbows with the center-to-end dimension of 1.5D radius which equals to 1.5 x NPS in inch unit. The standard long radius elbows of ASME B16.9 can be further classified as 90° and 45° according to the angle of the flow-direction change.
