Regarding the pressure test of accumulators
Thread Content
I wonder if any of my colleagues have conducted pressure tests as part of the regular inspections for accumulators. Do people usually use air pressure or hydraulic pressure for these tests? Are there any standards or guidelines regarding this?
We carry out hydraulic pressure testing; I don’t know what the pressure and volume you are referring to are. The new code now allows for three types of pressure testing: hydraulic, pneumatic, or a combination of both; one can choose the method that suits the specific circumstances.
Haven’t the new capacity regulations been issued yet? Is your place being regulated based on those regulations?
Today, accumulators are basically tested under hydraulic pressure; who still conducts pneumatic testing? :o The pressure used for the pneumatic test is so high that the impact of explosion poses a serious risk, hence high safety protection requirements are necessary.
Will the water pressure used by the unit during operation cause the internal components to rust?
