Hi guys - wonder if you can carify something for me??

The MOM decribes a pressure vessel as:

"A pressure vessel is a container or a vessel which contains any substance above atmospheric pressure."

Are there any limits on vessel size / pressure where the MOM is not required.  We make Pressure Vessels from ST. STL. for filtration purposes (gases & liquids) ranging from 2.5" Dia to anything upto 24" and sometimes above.  Are even the small vessels covered by the MOM factories act??

Our sales contact in Singapore is telling us not, but we the design office think they are.....

Thanks in advance,
Lee

Thanks deanc,

I have read the FAQ previously and have checked with Lloyds our AIA and they have said the same as you - a design review is required.  We keep telling the guys out in Singapore that this is required, but this was their response:


"I have check with MOM, filter vessels are not inclusive in the inspection lists. Only the compressor and the air-tank are consider as pressure vessel, and they are require to be inspected by certified inspector."


Things like this are clouding our judgement!!
Thanks,
Lee

Well----Things are sometimes different on the Pacfic Rim. Have run into this before.

In this case I would practice CYA. If sales says no design review is required they should provide you a document or email for the same.

It could be that vessels containing water and water with air cushion are indeed exempt from pressure vessel status by MOM. For example, certain Jurisdictions in the US exempt water filtration vessels (sand filter and demineralizer/conditioner vessels) as pressure vessels.
