How long is the valid period of a burst disc on pressure vessel equipment?
Thread Content
Dear friends from Sichuan, how often should rupture disks on pressure vessels be replaced? Are there any standards or regulations regarding this? Thank you
The standards do not specify this explicitly; companies can determine it on their own based on their production conditions
Generally, it is 1-2 years; if the operating conditions involve corrosion, the replacement cycle should be shortened accordingly
Please refer to the provisions in the Regulations on Safety Inspection for Shrapnel; it states that the period is two to three years, and under harsh conditions this period should be shortened
In accordance with the safety supervision regulations for rupture discs.
Will there be such a statement on the certificate of conformity?
Take a look at this; there are detailed regulations.
