Help need - pressure test procedures

[Josip]

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 :)

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

Stength test: 1.1 x maximum allowable pressure (MAP)
Tightness test: 0.95 MAP

Hope this helps

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.
