Calculation of orifice ratio for small-diameter orifices
Thread Content
Please, experts, help me figure this out. According to our throttling device standard GB/T 2624.2-2006, the allowable range for orifice plates is 50mm≤D≤1000mm. But during the design process, we often encounter pipe diameters
I’m also looking for the specification version 2624-81. Could anyone please provide it? I can’t find it for download anywhere online
Standard 81 has already been abolished; why look for it then? Non-standard throttling elements can be used. Or in some other form.
It seems that the orifice plate is only available in version 81; for most applications with small diameters where high precision isn’t required, using an orifice plate is the most cost-effective option
Buy a software; it costs a few thousand yuan. Small diameters are considered new cases as well, and they can be calculated too
Small diameter – find a turner to machine a tube inside the valve body; it’s much better than using an orifice plate......
