Abstract
ASTM A234 WPB Elbow is one of the most used forms of pipe fittings. An elbow is a connector shaped like an elbow and allows for directional transformation in fluid flow. A234 WPB Elbow is produced and supplied in the butt welded form. SA234 WPB Elbow usually comes in either of three angles; 22.5, 45 or 90 degrees. A234 WPB SCH 80 Elbow is a standardization that conforms to schedule 80. ASTM A234 WPB Elbow could also be threaded or machined; sometimes it is also socketed.
SA234 WPB Elbow is made up of carbon steel or alloy steel. Depending on the needs of the application, the A234 Wpb Elbow Dimensions vary. They can be applied to all nominal sizes of pipes. A234 Wpb Elbow Weight is mostly dependent on the material, diameter and length of the fitting. Elbow 90 A234 WPB indicates the degree of directional change by 90 degrees.
