    Question 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

    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.


    Cheers
