90°Elbow

An elbow is a crucial connection piece in piping systems used to change the direction of fluid flow. It is widely applied in industrial, construction, and civil fields. Its primary function is to adjust the flow direction of fluids through curved pipe sections to accommodate pipeline design and layout requirements.

Definition and Classification of Elbows

An elbow is a pipe fitting used in piping systems to change the direction of the pipeline. It is typically classified by angle into 45degree elbow,90degree elbow and 180 degree elbow. Additionally, there are special-angle elbows such as 60 degree elbows, based on engineering requirements. According to the bending radius, elbows can be divided into long radius elbows (with a curvature radius of 1.5 times the pipe diameter) and short radius elbows (with a curvature radius of 1 time the pipe diameter).

Materials and Manufacturing Methods of Elbows

Materials used for elbows include cast iron, stainless steel, alloy steel, carbon steel, non-ferrous metals, plastics, and more. Manufacturing methods include welded elbows, stamped elbows, cast elbows, etc. During the manufacturing process, to improve welding quality, the ends are usually beveled and left with a certain angle and edge.
