Se référant à la norme ASTM A967, la passivation se produit habituellement naturellement sur les surfaces en acier inoxydable, mais il est nécessaire de soutenir le procédé avec des traitements chimiques. Dans le cadre d’une altération de la matière par action mécanique, marquage laser etc., la qualité et l’épaisseur de la couche passive se développent rapidement et sont optimisées pendant les traitements de passivation à l’acide.

The venturi tube has a convergent inlet, a throat and a divergent outlet. It is a differential pressure flow meter well known to create a low permanent pressure drop; thus, it is suitable for measuring, for example, a low pressure flow rate. More over, it requires short upstream and downstream straight lengths.
There are different types of venturi tubes : the machined venturi made from a solid round for small size parts, the rolled welded venturi made from sheet metal for larger pieces up to 1200 mm diameter and the venturi "as cast" allowing a better accuracy up to 800 mm diameter.

Orifices: dimensioned according to the fluid, the pressure drop or the flow to be achieved going through the restriction.
Plate thickness: calculated taking into account the pressure drop generated by the plate and the diameter of the pipework in order to avoid a deformation of the plate. For more details, see our Frequently Asked Questions.
Noise: the number of orifices is determined according to the level of noise not to be exceeded.
The maximum noise level depends on the operating conditions: limited to 85 dB(A) by the regulatory body for an average daily exposure in continuous operation. Intermittent or emergency operation - acceptable upper values (see corresponding regulations).
If the noise level is still too high, it is possible to switch to a multi-stage restriction orifice.
Cavitation: the cavitation level is checked for each plate and the orifices are calculated to avoid cavitation. For more information on cavitation, see our Frequently Asked Questions.
