Pressure Vessel (Piston accumulator)
Pressure Vessel (Piston accumulator)
(OP)
I understand that AS 1210-1997 specifies requirements for materials, designs, manufacturing, etc. for pressure vessels up to 21 MPa(3046 psi). I have a requirement to provide piston accumulators that would be 5000 psi (34.4 MPa). Is there another mandate for higher pressure vessels? Please help...

AS1200 is the umbrella code to look at for the applicability. I could not find any specific clause for inclusion or exclusion of the accumulators. However, if we accept them as an air receiver, the design and manufacture is in accordance with AS1210 under AS1200 Table 2.1.
I personally would not recommend using the Supplement 1 because of the complexity, and otherwise you need to be very specific for the loads in/on the vessel.
Hope it is helpful.

The compliance with AS 1210 doesn't preclude the use of modern software (unavailable for design based on AS 1210). However, the use of software based on ASME, PD or EN standards in compliance with this old AS 1210 standard would require difficult modifications of the software database and the chance of not getting ever your design approved by some 'recognised' verifying agencies.
You need to be very careful in clarifying with your client the basis of design, including allowable stresses, method of calculating the nozzle and shell stresses due to nozzle external loads (refer to WRC 107 limitations!), otherwise you will never get the design approval unless you pay the agency with your blood. That's how AS 1210 makes money to some...in association with the ignorant local authorities requesting blindly compliance with AS 1210.

Remember - you are not building to AS1210.
