What standards are used for centrifugal fans? Is API673 mandatory for use in domestic chemical plants? Are there corresponding standards in China? Is it SH/T 3170-2011, the Technical Specification for Petrochemical Centrifugal Fans?

API673 sets higher standards than SH/T 3170-2011; the level of impeller balancing and vibration control for fans in China still has a long way to go. Setting such high standards means that no manufacturers are able to meet them, or the process is monopolized, which is detrimental to the entire industry.
