Burst Disk Question

[badlandsrox]

I was just reading the article on burst disks, and it said that the disks should be rated to between 1800, and 2500 p.s.i. But i was just looking at my tank, and it has a 3500 psi burst disk in it, i was just wondering if this is safe

Thnx

[QAZ123]

Is it a c02 or hpa tank?

JB.

[OtterSC]

what type of tank?

CO2 tanks should be 1800 rated.

3,000psi HPA/Nitro tanks should be 3,500 rated and the 4,500psi HPA/Nitro tanks should be 5,000 rated.

[badlandsrox]

its a 20oz co2 tank (made by pmi)

[OtterSC]

then the burst disc should be 1,800psi.

[badlandsrox]

so i should probly replace it then? if thats the case i should probly get it hydrotested too right?

[Ares]

u dont need to retest it

[OtterSC]

no need for retesting

It can be a "3k" burst disk. the 1800WP ones are displaying the Working Pressure of the tank, and burst at 3,000psi. So either is acceptable.

The standard has changed. It used to be 1800psi but is now 3000psi for C02 tanks -
