&#What does 216;33.4-Ø18 mean?
Thread Content
Welded globe valve, Ø33.4-Ø18, DN10, 15NiCuMoNb5-6-4, 40MPa@313.6℃; what does Ø33.4-Ø18 mean?
It indicates that the diameter of the stop valve ranges from 33.4 to 18 mm.
Could it be a change in diameter? 33.4-18 should indicate a thicker tube.
The answer above seems inaccurate; the diameter is specified as DN10, and it’s understandable that the outer diameter of the welded pipe is 18. However, I’m not quite sure about a diameter of 33.4
I don’t understand. Is it socket welding? If so, then these would be the inner diameter and outer diameter. Guess.
I’m not familiar with fittings; I’m more interested in materials. Are such fittings available in stock? ? ? For pipes made of this material, there isn’t much in stock right now···:)
The valve stem nut diameter is 33.4, and the valve stem diameter is 18 mm?
Specifications and dimensions of the end nozzles at the two welding ends
It’s a socket weld valve, right? In this case, the inner diameter of the valve’s socket weld interface should be equal to the outer diameter of the DN10 pipe, which is Ø18; while the outer diameter of that same interface is Ø33.4. Please check to see if this is correct.
