When milling stainless steel pipes, the compromise between milling rate and service time is the decisive factor affecting economy. In a test, the steel bag was subjected to fifteen wet cuts and then ten dry cuts. During the long run, the knife tube and slight free surface wear will occur, so all steel bags should be processed wet in the future. Then a profile milling cutter with a diameter of 81 mm and six blades is used. At the same cutting value, the flat surface above the stainless steel stamping elbow bag is dry milled for 16.7 minutes, which significantly improves the service life of this stainless steel stamping elbow compared with the competitor's disc tool.

What are the main types of stainless steel seamless and seamed elbows? Below, I will explain it to you in detail:

1. Pipe fittings with flanges and round edges, the former refers to the pipe end convex to the inside or outside, and the latter refers to the pipe fittings with bulges or grooves formed in the circumferential direction of the pipe;

2. Stainless Steel Weld Fittings variable wall thickness pipe fittings, which means that the wall thickness changes along the length of the pipe;

3. Stainless steel elbow bending pipe fittings, which we are more exposed to, are to change straight pipes into curved pipes with different curvature radii, such as elbows, elbows, etc.;

4. Stainless steel elbow variable diameter pipe fittings, which means that the diameter of the pipe end or a part of the pipe is reduced;

5. Pipe fittings with curling and bottom sealing, which increase the total strength of the pipe end by curling to the outside or inside of the pipe or sealing the end of the pipe fitting;

6. Pipe fittings with changing cross-section, according to requirements, change the circular cross-section into square, elliptical, polygonal, etc.
