The long radius elbow has a bend radius that is 1.5 times the elbow diameter. This 1.5D long elbow is the most popular elbow in the project. Usually the angles of the LR elbows are 45°, 90° and 180°, respectively. Long radius elbows are used where pressure is high or flow rates are high. Long-radius elbows are preferred if there are no conditions or are not specified in the contract.
Its use includes sewage treatment, chemical, thermal, pharmaceutical, aerospace, electric power, paper and other industries.

The functon of using a 1.5D elbow in the pipeline:
1. Reduce the stress of the pipeline and increase the flexibility of the pipeline, which is common in thermal oil pipelines.
2. Reduce the pressure drop of the pipeline.
3. Reduce the fluid dynamics of the pipeline to the pipeline while reducing the dynamic load of the fluid on the pipeline system.
The long radius elbow is a pipe fitting that modifies the direction of the pipeline. It exists in the system of the pipeline and is widely used in the chemical, petroleum, metallurgical, national defense, light industry and other industries.
