[MW:22296] RE: 22295] Pressure test gauges clarification

Dear Santosh,

 

The 5% difference mentioned below is the difference in reading during testing and not 5%  difference on Gauge scale. So you can use both together in one test (if calibrated ofcourse).

 

Met vriendelijke groeten / Best Regards,

Onderwerp: [MW:22295] Pressure test gauges clarification

 

Dear All,

 

Can anyone tell me What is the minimum gauge range difference in a pressure testing?

 

Let me explain clearly, now my hydro test pressure is 10 bar. As per ASME Sec VIII Div 1 UG-102 TEST GAGES and ASME Sec V ARTICLE 10 LEAK TESTING T-1030 EQUIPMENT I can use pressure gauge range 1.5 to 4 times of the test pressure i.e. 0-15 Bar to 0-40 barg.

 

Now my question is can I use these both the gauges (0-15 Bar to 0-40 barg) in a single pressure? If yes please give me code reference.

 

There is an argument saying that the "minimum of two pressure gauges shall be within 5 % of one another when in use"

 

 

Thanks in advance.

 

Regards,

Santosh.
