Safe distance during Piping hydrotest

Safe distance during Piping hydrotest

Safe distance during Piping hydrotest


This is an old topic discussed earlier . (thread292-225652: Hydrostatic Testing Safety)  Safe distance during hydrotesting.
The formula discussed was

safe distance = (0.15) x (D) x (a)^0.4 x (p)^0.6

where  D - internal diameter (m)
       a -  length / diameter of piece (m)
       p - test pressure  (bar)

The code reference given was Norwegian specification T0240|72-12| and in the footer "Rules, issue 96-02".

is it possible to know the title of the Norwegian Code which is referenced in earlier discussion?

A similar discussion on CR-4 FORUM http://cr4.globalspec.com/thread/17841/Safe-Distance-for-Pressure-Testing
Gives reference to "Netherlands Stoomwezen Rules for pressure vessels


Would appreciate if anyone can clarify  the source of this formula for calculating safe distance during hydrotest.
Thanks in advance

RE: Safe distance during Piping hydrotest

The Spec number given is a Dutch Stoomwezen Code.

RE: Safe distance during Piping hydrotest

Thanks DSB
Could you please let me know how to access/ buy this dutch code?
Any web link will be greatly appreciated


RE: Safe distance during Piping hydrotest

Australian and New Zealand Standard AS/NZS 3788:2006 D16.2
