it's the first mail I send to this forum (entered a few days ago..I do not
know even if it's correct to reply to this address….): regarding your query
about DFT, a GE O&G standard requires -10% +40% on each layer DFT, 12944-5
Sect.5.4 says -20% and +300%: personally I think Customer Specs, Paint
Manufacturer Specs, direct experience on each equipment are all relevant
topics to be considered for every application.
You can also refer to ISO 2808 for methods.
And…pay attention always to guarantees/durabilities…

Hi Jivan,
With respect to your query 2 ( Tolerance for a Given DFT measurement),
please refer Para 5.2 of SSPC-PA 2 of SSPC Painting manual Volume 2.

Dear Mr.Jivan,
Pneumatic testing of reinforcing pad is npt mandatory . But you need to see
the purpose being served by the pad. If it is a pad to attach a structural
part where no through opening is made, it is not required. However if there
is a through opening and such opening is being reinforced with a pad, you
need to examine the weld integrity between the pad and the branching nozzle
. Therefore it is a standrd practice to do pneumatic test of such pad and
you will be able to see the weld at Pad to Nozzle , Pad to mother pipe /
veseel which is typically a fillet weld and if accessible , you also can
see the weld of branch nozzle to main pipe/ vessel examining at inside .
I beleive that underlying inetent of test is realised now.
WithBest Regards,
Tagore

the below queries. If my question is not correct then let me know means i
will correct it.
Dear Friends (Dated :- 18/02/2009)
I would like to know whether Pneumatic Test of Reinforcement Pad for branch
connection of Process Piping is mandatory as per ASME B31.3. I searhed but I
could not found any paragraph in ASME B31.3.

Dear Friends ( Dated :- 03/03/2009)
I would like to know the maximum acceptable Dry Film Thickness of the paint
in % or micron for a given DFT. As per my previous experience (where I
worked) as per specification that was plus/minus 30% of the total paint DFT
was accptable. But I couldn't found any code or standard documents related
to the maximum acceptable dry film thickness of the paint.
If you have any code or standard then let me know the same means i can refer
same. i need this information for piping job as well as tank job.
Regards
Jivan Dhamane
