Flow loss problem in the eye digging tee
Thread Content
I would like to ask everyone: does creating an elbow in a pipeline result in greater flow loss compared to using a regular elbow fitting?
1 Pipe tapping tee? Should another branch pipe be connected after making a hole in the pipeline? Factory-fabricated tees are produced by die extrusion or drawing. 2. List a few apparent differences: 2.1. The surface finish of the holes in the former type is poorer ； The inner surface of the latter pipe is continuously smooth. 2.2. The openings in the former are generally smaller than the inner diameter of the branch pipes ； The latter can have the same diameter as pipes, 2.3. The former has an opening at the fluid passage point that causes a 90° turn, resulting in eddies ； The latter provides a smooth transition and reduces eddy currents; these differences result in greater drag reduction for the former compared to the latter
An eye-shaped tee is what is known as a socket-welded tee. The disadvantages are: the opening is at a right angle, the diameter is relatively small, the inner wall is difficult to treat, there are welding scars, and the resistance to fluid flow is high. If the welding quality is poor, leaks are likely to occur.
