Description

Technical Field

[0001] The utility model belongs to the technical field of metal elbows, and in particular relates to a metal elbow. Background Art

[0002] In the piping system, elbows are pipe fittings that change the direction of the pipe. According to the angle, there are three most commonly used elbows: 45°, 90°, and 180°. In addition, according to the needs of the project, there are also elbows with other abnormal angles such as 60°. The materials of elbows include cast iron, stainless steel, alloy steel, malleable cast iron, carbon steel, non-ferrous metals and plastics, etc. However, in the existing technology, if the two ends of the 90-degree elbow are damaged, it is inconvenient to replace the damaged ends, resulting in a shorter overall service life of the elbow.
