Patent

CA 2657470

A flow meter tube (60) is provided having improved performance in the measurement of the flow rate of erosive material. The internal wail (72) surface of the flow meter tube has a smooth erosion-resistant coating (74) thereon to protect the flow meter wall from erosion by the erosive fluid flowing there through. The coating has a Rockwell C hardness of 56 to 70 and a surface roughness of less than or equal to 250 microinches rms.

L'invention concerne un tube de débitmètre (60) dont la performance de mesure de débit de matériaux érosifs est améliorée. La surface intérieure de la paroi (72) du tube de débitmètre est recouverte d'un revêtement lisse résistant à l'érosion (74) afin de protéger la paroi du débitmètre de l'érosion créée par le fluide érosif circulant à l'intérieur. Le revêtement possède une dureté Rockwell C de 56 à 70 et une rugosité inférieure ou égale à 6.4 µm rms.
