Is it required to have a relevant operation certificate for any installation that involves pressure pipelines or pressure vessels?

Proportionally speaking, not everyone in our unit took the exam

Do you know what the standard is? In my previous workplace, it was two per shift; I’m not sure what determined that number – or whether one was enough

This document has been released: the Office of the State Administration for Market Regulation’s Implementation Guidelines on Matters Related to Administrative Licenses for Special Equipment (Market Regulation Special Equipment [2019] No. 32). The certification required for workers operating special equipment has been abolished for pressure pipelines. As for pressure vessels, the rules vary: mobile pressure vessels used for filling R2, as well as oxygen storage tanks classified as R3, still require certification; however, R1 pressure vessels are now considered quick-opening pressure vessels, and certification is based on a commitment system. If a company previously used a compressed air tank, it is no longer necessary to take any examinations in this case； However, enterprises that originally use fast-opening pressure vessels such as high-pressure dyeing vats and sterilization tanks need to obtain an R1 certificate. Moreover, under the commitment system, if the certificate expires and the company decides not to renew it, then by committing that it does not involve quick-opening pressure vessels, it can refrain from obtaining a new certificate, bearing the consequences thereof. Of course, if you’re not sure, it’s best to ask. For example, an old-fashioned dye vat uses a swivel bolt structure that allows for quick opening, but it is not considered a pressure vessel designed for quick opening. . . . . As for the quantity, startup companies are responsible for it; when nothing goes wrong, 3.4 units is acceptable, but if an accident occurs due to operators working without proper licenses, the penalty is even greater
