Classical Venturi Tube H 800

Construction

A venturi tube is a device composed of a confuser inlet 
cone, a cylindrical throat and a diffuser outlet cone. 
The differential pressure measurement can be taken 
through one bore or through four, that access to a 
annular ring chamber. The venturi tube is drilled or 
welded out of steel or stainless steel, with flanges at
each end or for welding. The interior can be plastic-coated.

Advantages

Wherever pressure, and therefore energy loss must be 
Avoided and short pipe runs are given, Venturi Tubes 
are used. In comparison to orifice plates, the remaining 
pressure loss is about 80% less than that caused 
by the sudden constriction of an orifice.

Technical details

Nominal pressure: PN 6 ( 150 Ibs) up to PN 100 (900 Ibs)

Nominal diameter: DN 50 (2") up to DN 2000 (80")

Bore diameter: the calculation is made by us from the data supplied, considering the relevant standards.

Pressure loss: the remaining pressure loss, depending upon the ß-ratio of the venturi. This can be 10-15% of the dynamic pressure. Shown in data sheet.

Pressure taps: these are described in sheet A6. If required, the venturi tube 
can be supplied with more than two pressure taps.

Installation: Between flanges or for welding on horizontal,
vertical or diagonal pipelines.
Quality assurance: Manufacture and testing according to the relevant guidelines, 
i.e. TRD, AD-Merkblatt, ANSI and/or customer's specification.
