Abstract
Tubing or pipe bend or elbow for use in carrying pneumatically conveyed granular material has an axial bore with an input opening at one end and gradually diminishes to a smaller opening at the output end, such that the incoming material sees a pressure relief, or drop, at the input to the bend. As a feature, a tubing bend may be segmented, i.e., made out of a series of separate or individual bends with the output of one coupled to the input of another.
