Re: [MW:22299] Pressure test gauges clarification

Dear Santhosh,
 
As per my knowledge,
 
"minimum of two pressure gauges shall be within 5 % of one another when in use"
 
This means when you have pressurised  the vessel or equipment the  pressure difference in both the gauges shall be within 5% errror.
Like when you pressurise the equiment to 10 bar then both the gauges should show within 5% error( 10 bar or10.5 bar)

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.
