Swedish Pressure Vessel Code?

03/31/2011 1:15 AM

Hello all I hope someone out there has knowledge of Swedish pressure vessels. I have just inspected a small air receiver with a very faded printed & stamped aluminium specification plate. From the little I can read I think it originated in Sweden; Ar - Year? 73, Ma - Month? 5 ; HTT 10 - is this 10 bar design pressure?; serial number 5643; KTTA 600/350 - is this the design code or the manufacturer and model number; Besman JB - Inspector? The vessel passed a pressure test (15bar) and thickness survey so I am reluctant to pension it off just yet but I would like to be sure I have interpreted the specification correctly.

I'm guessing you're retesting this to see what it is good for. Do you have a U-1 or something documenting it's MAWP and the %radiography? That goes into the joint efficiency.

Try googling the rest and see what comes up.

Thanks cingold, for the response; there is no documentation and I had little joy with Google. I was carrying out the first 'statutory' inspection in probably 20 years; this is Africa and things don't happen with the same urgency as elsewhere. My analysis and testing shows that it is OK for 10bar but I will have to give it a limited future life span if I cannot interpret the specification plate.
