Valve Qualification as Part of the Purchasing Decision

Qualification testing, albeit beneficial, should never be the sole basis for a valve purchasing decision. 

Qualification testing benefits the purchaser and manufacturer but should never be the sole basis for a purchasing decision. It is only part of the information...

Scaling Laws In Process Engineering

Capital cost estimation techniques in the chemical process industries (CPI) largely rely on scaling relationships. Understanding how scaling relationships relate to equipment characteristics enables them to be more effectively used, even when specific data is not available....
