Description

Technical Field

[0001] The utility model relates to the technical field of steel pipe elbows, and more specifically, to a steel pipe elbow with an extension function. Background Art

[0002] In the management system, elbows are pipe fittings that change the direction of the pipeline. They are divided into three most commonly used angles: 45°, 90° and 180°. In addition, other non-normal angle elbows such as 60° are also included according to project needs. The materials of elbows include cast iron, stainless steel, alloy steel, malleable cast iron, non-ferrous metals and plastics.

[0003] Based on the above, the inventors found that: at present, the existing steel pipe elbows are usually fixed and cannot be extended. Workers need to measure and cut the steel pipes in advance when installing the steel pipe elbows and steel pipes. Small errors often occur during the cutting process, resulting in non-standard lengths of the steel pipes and difficult installation. Therefore, in view of this, research and improvement are conducted on the existing structure to provide a steel pipe elbow with an extension function, in order to achieve a more practical purpose.
