The customized 180D elbow is one of the pipe fittings. The purpose of the elbow is to connect the pipe into a pipeline part. According to the connection method, it can be divided into four categories: socket pipe fittings, threaded pipe fittings, elbow pipe fittings and welded pipe fittings.

In the customized 180D elbow piping system, the elbow is a pipe fitting that changes the direction of the piping. According to the angle, there are three most commonly used ones: 45° and 90°180°. In addition, according to engineering needs, it also includes other abnormal angle elbows such as 60°. The materials of customized 180D elbow include cast iron, stainless steel, alloy steel, forgeable cast iron, carbon steel, non-ferrous metals and plastics. The ways to connect with the pipe are: direct welding (the most common way) flange connection, hot melt connection, electrofusion connection, threaded connection and socket type connection, etc. According to the production process, it can be divided into: welding elbow, stamping elbow, push elbow, casting elbow, etc. Other names: 90 degree elbow, right angle bend, love and bend, etc.
The variety of products, stamping customized 180D elbow is widely used, and the service life of pipe fitting elbows constitutes a large-scale high-tech industrial cluster and has a very broad market prospect and important strategic significance.
1. High pressure applications
2. Large impact applications
3. High static friction applications
3. Large impact High pressure applications
High pressure applicationsAll the applications were considered in the research. The application scenarios were analyzed which were high pressure applications but they were still compatible with the original design. In the high pressure applications where the elbows are fixed inside of the vehicle body in a static position that requires the maximum potential energy and kinetic energy, the design is modified so that it can not be displaced by the wind which blows the vehicle body. In such a position, the system would only require the maximum possible kinetic energy as the angle of contact with the vehicle body is fixed.
