Is it common practice to do HIC testing on forgings? (In sour services)

PVHO last line of 1-5 says that a Registered Professional Engineer has to certify the Manufacturers Data Report for a PVHO. Is that the U-1A form from Section VIII-1 which is to be completed after hydrotesting etc.? Or is the complete design (drawing, calculations and material specifications)...

LS. ASME PVHO-1-2007 1-7.6 (a) says: "Penetrators shall be constructed of material suitable for the intended service and compatible with the vessel shell material" Still I have seen PVHO's (decompression chambers) made of SA516-60 plate with stainless steel penetrators welded in. Please advice

LS. Does anyone know anything about the availability of acetyleendyssous and oxygen (to be used for flame cutting), Ar/Co2 shielding gas for GMAW and dieselfuel near Shanghai, China? And what the Voltage is and the alternation? Thanks in advance.

LS. What will be the effect on wallthickness etc when a horizontal storage vessel with a self supporting roof, slope 1:5 dia 81' cilindrical heigth 46' acc. API 650, has to be designed for seismic loads? (Loc. California) Thanks in advance.

Does API 582 have restrictions regarding the thicknessrange of the basemetal cladded? E.g. having a testplated of 20 mm cladded with Alloy 625 give that us the possibility to clad base material > 20 mm?

We have tested a piece of SA350 LF2 with specimen thickness of 3 mm at -40°. Now Both ASME VIII-1 and B31.3 say that our minimum design temperature should be 22.2°C higher.(-40°-22.2°= -17.8°C). In other words for a min. design temperature of -40° we should have been testing at -62.2° (-40°C...

L.S. Can anyone tell me what the K-value is for a carbonsteel-heatexchanger when the medium on both sides is water?

Is hot dip galvanising an essential variable which requires requalification of a pqr non-pwht?

I know that API 6A WN flanges with the same dimensions as ASME WN flanges have a larger rating. I found a table where is stated that p.e. ASME 1500# is equal to API 6A 5000#. Where can I find the ASME equivalent for API 6A 10.000# ? To make orifice plates I need the seating dimensions. Thanks

Does any one know if the max. thickness for P-No.1 material not requiring PWHT in Table 331.1.1 in the latest issue of ASME B31.3 is increased from 19 to 20 mm?

Can anyone give advise about pwht for welds in 24 mm A516-60 and A240 type 321.

Does ASME B31.3 require RT examination after any heat treatment or is it allowed to perform RT previous to PWHT and perform additional MPI after the heat treatment?

Do we need a CSA approval for an ASME "H" stamped heating boiler body (without any electrical device) stamped with an CRN? If so how to obtain that CSA approval? When a burner and other devices are fitted to the boiler do we need a separete CSA for every device or only for the complete package?
