The three-way problem
Thread Content
Is there a tee with an outer diameter of 114 for the pipe, and an outer diameter of 76 mm at the outlet, that is, of the size 114*114*76? If so, what criteria should be applied? GB/T 12459? However, 114.3 belongs to series 1, while 76 belongs to series 2; the standard does not specify whether the pipe side should be of series 1 and the outlet side of series 2 I’m very puzzled. And how should such a tee be labeled? DN100*65? Still DN100*65 Ⅱ
Standard parts are likely not available; a custom one can be designed based on an external shape diagram.
Such non-standard parts should be difficult. . Because the program is fixed by the mold. . If I were to do it, I would make it 114*114*73, and if that dimension is greater than 73, I would expand the interior by import methods (such as using spherical supports) to 76
Under normal circumstances, the specification is still DN100*65

On the pipe layout diagram or axonometric view, it can be indicated as DN100XDN65; in the specifications column of the material list, write 100X100X65. Then in the remarks section, indicate II series SCH value (based on wall thickness) and *series SCH value (based on wall thickness). This is for reference only.
