Orifice plate maintenance
Thread Content
What should be done in the case of damage to the inner tube of a standard throttling device, especially an orifice plate? I wonder why, with such clever methods, the flow coefficient isn’t changed and accurate measurements can still be taken?
Orifice plates should be calibrated regularly; those that fail the inspection should be replaced, or recalculated after repair.
If it breaks, just replace it; the price isn’t too high either! Fixing it still costs money! The corrected flow coefficient needs to be recalculated, and it is difficult to ensure consistency.
Under what circumstances can the inner tube of a orifice plate be damaged? I’ve never encountered it; the measurement accuracy of orifice plates isn’t very high. It would be better to use one if necessary!
If it is a standard orifice plate, only the orifice disc needs to be replaced, which is not very expensive. Just provide the process parameters.
