pneumatic test of RF pad of nozzle

[Rahul Chaudhari]

Dear all ,

Can some one Tell me that why are we take pneumatic test of RF pad of
pressure vessels nozzle???

[TDK YOKESH]

Warm Greetings ,

We don't call it Pneumatic Test . We call it Leak test which is done to check weld integrity at the RF pad and nozzle by applying pressure through the vent hole and check the weldment with Snoop solution .

Dear Mr.Rahul,

The pneumatic test of RF pad is done to ensure that no leak is there inside the area of RF pad. That is, particularly in the nozzle to vessel joint and RF pad to nozzle joint. The integrity of  fillet weld of RF pad to vessel is also ensured by this process ( It is ensured that no leak is  there inside the RF pad, due to welding of the RF pad to vessel joint)

In the pressure test of vessel, leak inside the RF pad may not get detected, if the % of leak is very less.

Regards
Hareesh K V

Yes. It is called air leak test. Normally the pr is little more than 1 bar and checked by soap solution or any other method
