Air Reciever Tanks Fabrication
Air Reciever Tanks Fabrication
(OP)
Hi all...
I work as a Detailer with a company which supplies pre-fabricated piping for process plants. The company is building a new facility now.
Yesterday I received 2 vague drawings of air receiver tanks (for the new facility) and my boss told me we are going to fabricate these
2 air receivers here!!!
We don't do PV fabrication and we don't have U stamp certification either.
What they might have done is, they have copied some drawings which were readily available in the internet and decided to proceed with the
fabrication of them. Now detailing those 2 vessels is my responsibility. Though I have some knowledge on PV design and detailing, I really
wonder if it is ok fabricate just with some drawings (without doing design and analysis).
QA/QC manager argues "We do not have to Code Stamp these Air receivers if we are the end buyers.
We'll only follow all ASME Sec VIII Div 1 requirements for Fabricating them with our internal Quality Checks"
I would greatly appreciate if you could assess this scenario to me coz if anything goes wrong, I'l be the "scapegoat" in the "Blame game".
Below are the details...
2 Air Receivers 1 for 2500 gal. and the other is for 5000 gal.
2500 gallons receiver--
Dia 60"
Height 235" (approximate LOA)
shell .25 Nom SA455
Heads .312 Nom SA516 Gr 70 matl.
Working pressure 150 psig
5000 gallons receiver
Dia 72"
Height 235" (appr. LOA)
Shell .375 Nom SA455
Heads .375 Nom SA526 Gr 70
working pressure 150 Psi
(If anyone can provide me any specific drawings for these would be a lot helpful.)

In what state will these vessels be fabricated ?
Where will they be installed ?
RE: Air Reciever Tanks Fabrication
I have partly been able to convince the higher ups here about the regulatory issue and they are now looking out for some design firm to deal with this...
Vessels are fabricated and installed in UAE/Arabian Gulf.

The stored energy at 6 atmospheres in a 1M dia x 2M long air tank is similar to a kilo of TNT. Ask the boss ifhe minds if you start working with TNT, since there are no pesky ASME or EN Codes to comply with in the country you folks are working. Nothing to forbid engineering foolishness.
