ASTM A234 WPB B16.9 L/R CARBON STEEL 90DEG ELBOW
The 90-degree bend allows for changes in pipe direction, enabling the routing of piping systems around obstacles or to accommodate changes in the layout. The carbon steel construction and standardized dimensions make these elbows a durable and versatile choice for piping applications. Proper welding techniques and installation procedures are crucial to ensure the integrity and safe operation of the piping system.
- The 90-degree elbow is made from carbon steel, typically conforming to standards such as ASTM A234 WPB or ASME B16.9.
- Carbon steel provides high strength, durability, and corrosion resistance.
- The 90-degree elbow is designed for butt welding connections, providing a strong and reliable joint.
- Butt welding ensures a seamless and leak-free transition between the elbow and the connected pipes.

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.
