Thin, this 1: Is 3 the ratio of the opposite side to the adjacent side? Also, when two barrel sections with unequal thickness are butt welded, is the thinning of the thickness section also based on the ratio of 1:3? This 1: Is 3 the ratio of the opposite edge to the trimmed edge? I hope I can explain it in more detail. ； 3

The problem of butt trimming of cylinders with unequal ends is clearly discussed in Chapter 10 of GB150. There are many forms, not necessarily in proportion.
1: 3 is the ratio of the two adjacent sides of the right-angled side, the shorter 1 is the thickness difference of the butt joints of unequal thickness, and the long 3 is the length of the transition section.
1:3 is the tangent value. That is tan.
1:3 is the ratio of the maximum depth of the bevel to the length of the bevel. Please study GB150 carefully for details.
150 above...Chapter 10... gives the docking methods of different thicknesses, such as the connection between forged pipes and flanges, etc.···
What is the general thickness difference for trimming? What is the minimum thickness difference in percentage?
GB150-2011, 6.5.3 has a section about trimming, you can check it out
