Used to stabilize a flow of the measured medium ahead of the flow orifice device by means of the elimination or decreasing of vortex flows induced by local resistances.

  • It has a form of the cluster consisting of 19 tubes located in parallel to the pipeline axis and filling all its section.
  • It is manufactured in three versions. Connecting dimensions of straightening vane flanges, version 1 and 3 correspond to GOST 33259-2015.
  • To be mounted on a pipeline, a straightening vane can be supplied with a set of counter flanges.

Frequently asked questions

  1. A disc device (Zanker type) for the preparation of a flow and a tubular straightening vane are manufactured in compliance with GOST 8.586.1-2005. The aforementioned standards specify the hydraulic resistance k coefficient on straightening vanes. In particular, for the Zanker type the coefficient k is equal to 3.0, for a tubular - 0.75.
    Knowing hydraulic resistance coefficients k, one can calculate the losses of pressure in compliance with the formula of local hydraulic lossesone can calculate the losses of pressure in compliance with the formula of local hydraulic losses.
    dp = k * ro * u * u / 2,
    where dp — pressure losses;
          k — hydraulic coefficient resistance;
          ro — liquid density;
          u — average liquid flow velocity in the section.
