Re: [MW:4814] Impact requirement for non pressure parts.

Even though the internal parts are not subjected to any pressure load and non pressure parts , they can be subjected ceratin stresses due to flow chnages in the process( force, directional). Therefore , if the fluid being handled calls for impact test, it is prudent to have the non pressure parts also of impact test quality. Keep it in mind that most of the non pressure parts are of small thickness ( 6-10 mm) and therefore may get exempted from impact testing per fig UCS-56.

Dear all,

Is it required to use Impact tested Welding procedure WPS
( supported by Impact tested PQR) to weld vessel internal Parts?

I.e parts that are directly welded on shell/head(non pressure joints).

Vessel is ASME code stamped, Shell & heads base meterials require impact testing as per code.

can any body give code referances (ASME Sec.VIII Div.1/Div.II.
