What is the difference between long-radius steel elbow and short-radius steel elbow

1. Different definitions:

Long-radius steel elbow: Long-radius steel elbow means that the radius of curvature of the elbow is 1.5 times the diameter of the pipe; if it is greater than 1.5 times, it is in the category of elbows.

Short radius steel elbow: The short radius steel elbow means that the radius of curvature of the elbow is equal to the diameter of the pipe, which is often said to be 1 time.

2. Different applications

Long-radius steel elbows are the most commonly used. Generally, the default is also long-radius. Where the pressure is high or the flow rate is high, a long-radius elbow will be used. If the resistance requirements of the solid conveying pipeline are strict, a larger radius elbow should be used. The short radius is generally used in low-pressure fluid or where the elbow is limited. If there are no conditions or not specified in the contract, long-radius steel elbows are preferred.
