There are several types of elbows in GB/T3287: Elbow A, short elbow D, and long elbow G. Here’s the question: if I want to use a elbow, should I choose elbow A? Is it the short crescent D, or the long crescent G? What are the differences between these types? What are the differences in usage?

This needs to be determined by calculating the pressure and then selecting the type of elbow that results in the least pressure loss. There is no fixed method for selection.

This is related to the indenter loss! ? It’s just the difference between large curves and small curves; it can’t be just that simple, right?
