ASME B16.11 Elbow is made up of forged steel material in the range of 1/8 inches to 4 inches in nominal bore size. R.C. Metal Corporation is a leading supplier and manufacturer of the 45 Degree Threaded Elbow and various other types. The elbows are used to turn the direction of the pipes. There are different types such as the Socket Weld 90 Degree Elbows which has a socket welded onto it and has a 90 degree angle. The socket allows for maximum grip of the pipes. Socket weld fittings are used on small size pipes. The ANSI B16.11 Screwed Elbows has screws or threads on it. The threads are useful when welding is not preferred on applications.

There are different pressure classes to the elbows ranging from 3000 to 9000. The Elbow 90 SW 3000 is a socket weld 90 degree elbows that has a pressure rating of 3000Lbs. The different pressure ratings are useful in different applications. High pressure applications such as hydraulic pipe lines use the 45 degree socket weld elbow because the socket provides for maximum strength at connections as well. There are different types of materials used in the production of the Socket Weld Elbow 90 Degree and other types.

The materials range from 304 grade austenitic stainless steel to C276 hastelloys. Depending on the needs of the application, the material grade changes. The 90 Degree Screwed Elbow can be used in oil and gas industries, waste water management, pollution control systems, heat exchangers, condensers and in marine applications as well. The 45 Degree Street Elbow is used most next to the 90 degrees elbows. The elbows reduce the impact on walls by gradually turning the direction rather than a sudden turn unlike the bends. The 90 Degree Socket Elbow is one of the most used in small diameter pipelines. We supply different schedules, pressure classes, specifications and materials for Threaded Elbow Class 3000 and other classes and types. Please feel free to contact us for more information on the products, pricing and the different types such as the Threaded Reducing Elbows.
