Reinforced pipe joint
Thread Content
What does DN20*80 reinforced pipe fitting mean? What about WPD-03/01?
It’s 80 with 20 taken off from it; you need to figure out where that symbol comes from
The poster should provide more information; the amount of info available right now is a bit insufficient. DN20*80 should refer to a branch pipe diameter of DN20 and a main pipe diameter of DN80. It’s impossible to determine the meaning of WPD-03/01 just by looking at it literally.
That’s not right, is it? You are referring to a reducing tee. What the original poster is referring to are connectors; I think they are similar to things like bushings or reducing couplings.
I understand that by strengthening coupling, he is referring to couplings or half couplings, which serve to reinforce the branch pipes; that’s why there are parameters for the nominal diameters of the branch pipes and the main pipe. Let’s see if the OP can provide more information.
I think the latter is more likely, half coupling.
I think it should be DN20*SCH80; the number that follows is probably the system code
