Explanation of wall thickness marking for large and small ends
Thread Content
Explanation of wall thickness indicated by large and small diameter marks: In DN125XDN80Ⅱ-5 R(C), does the wall thickness of 5 refer to DN125, DN80, or is it 5 mm for both ends?
Ask the manufacturer about this issue.
It generally refers to the wall thickness of the larger end; if only one thickness is specified, it can be assumed that the wall thicknesses at both ends are the same. Just as in the budget specifications for DN100x80 fittings, the calculations for such fittings are done based on DN100.
If the wall thickness for the major and minor sides is not specified separately, then 5 means that the wall thickness for both sides is 5 by default

It should be tubes of the II series with a small outer diameter; since there is no SCH designation, the wall thickness is indicated directly, and 5 represents the wall thickness. As a supplementary note, it could also refer to the pipe wall thickness and material code of the manufacturer.
