Help need - pressure test procedures
Hi, all
Old chap need your help ... there is a new European Standard EN378-2008, (standard which unfortunately, I do not have) ... with some ???? changes....
Google was not of a big help ...but I believe to get more help here, as always
I need to make a pressure test (strength and leak) on a big ammonia plant ...
Regarding to maximum working pressure what are the pressure multiplication factors for strength and leak test pressure...
Thanks for any help.
Best regards, Josip

No job is as important as to jeopardize the safety of you or those that you work with.

Google BS - EN 378-2 2008 Refrigerating Systems & Heat Pumps - you can purchase the standards off the relevant linked site.
In South Africa we test to 1.1 times pressure vessel design pressure.
Good Luck

Re: Help need - pressure test procedures
Hi Josip,
Strength test = 1.3
Pressure test = 1.1
Air cooled condenser = 55 Degrees C
Water cooled condenser = 43 Deg. C
Low side of system = 32 Deg. C
If you pm me your e-mail address I might have a bit more infromation for you.
