Regarding the pipe fitting wall thickness series
Thread Content
Recently, I encountered a description for elbow material: schedule S-40XS-40 6.1/4“. This wall thickness series is something I’ve seen for the first time – is it part of the XS thick-wall series? Still SCH40; seeking advice from experts
Schedule S-40XS-40 6.1/4\" – this represents the multiplication sign, right? . . Variable diameter 6.1\" (S-40) X4\" (S-40)
I have heard of this type of representation before, but I’ve never seen it. To simplify things, we use the same wall thickness grade on both sides of the reducer. I would like to ask everyone: do manufacturers produce reducers or tees with different wall thickness grades on each side?
Ah, indeed. But the markings on the drawing are too... It looks like a capital X, and it doesn’t match the symbol “×” at all... Thank you!
It is indeed a multiplication sign, but on the drawing it appears as an uppercase X; the symbol “×” doesn’t match it at all – it’s actually an elbow
