Yes, I will use refractory after completed welding and fabrication. whether Inconel 182 can be used or not? please advice, I need recomendation.

I understood that the filler metal Inconel 182 (ERNiCrFe-3)SFA 5.11/SFA 5.14 will cover for design temperature 732degC, however this filler metal can't applied for equipment with design temperature 1000degC condition. any other recommendation for filler metal to be used for welding dissimilar...

thank you for response Inconel 182 (ERNiCrFe-3)SFA 5.11/SFA 5.14 only cover for design temperature 540degC as per API RP582, in this case design temperature is 1000degC. I think this filler metal will not suffice. please advice reference code and recomendation filler metal (if any)

Dear Expert, In this week, i preparing procedure qualification for welding, this WPQT for new WPS for welding V-anchor to shell/head The other information as below: Equipment : Reactor Reference Code : ASME Sect. VIII Div.1 Latest Edition Design Temperature : 1000degC Material : SA516-60N...

ASME Sect. VIII, the service of equipment is Wet H2S. the materil SA516-70N (HIC)

all requirement shall comply to ASME

Dear Professional, Now, i preparing procedure for heat treatment, i have equipment as below condition - Material SA516-70N - Extreme Fiber elongation over than 5% - PWHT should be performed due to special service, my question: whether we can performed PWHT only, due to stress relieve will...

Dear all, i have U-tube material with solution annealing due to extreme fiber elongation greater than 5%, material : SA312-TP304 Thickness : 2.11mm In mill certificate mentioned the holding time is 15 second. it is correct? please advise or give me reference whether 15 second is correct or...

thanks for your feedback the PWHT method already proceed as per UCS-56. but for the minimum holding time shall min. 60 minutes due to client specification. however, your explanation is technical. would you give me reference for calculate thermal analysis.

how to get product data sheet of hydrazine? and how about NaNo3? do you have recommendation?

thank you for your replied First, what is your idea of a thermal analysis? based on owner request but they not give requirement, rule, reference code. Why is a thermal analysis needed? we need thermal analysis due to identify/confirm the Weld metal, HAZ properly heated during local PWHT/PWHT...

Hi can we calculate thermal analysis on material when PWHT or after PWHT. please inform reference for calculate Regards KRN

i found spec hydrostatic test for column/pressure vessel mentioned that the water hydro test shall be mixed with inhibitor. the water shall have a maximum chloride content of 30ppm and shall in addition contain an inhibitor, the inhibitor shall be constituted of 3 ppm of sodium nitrate (Na...

my client suggest E NiCrFe-3, is it correct? i think incorrect due to different SFA no.

Dear Jithin214 for your reference Procedure PWHT ==> UW40 Procedure Local PWHT ===> UW40 and refer to WRC BULLETIN 452_JUNE-2000 Requirement PWHT for Carbon Steel ==> UCS 56

i found spec welding overlay and dissimilar weld from my client mentioned that AWS E309/E309L shall not be used when design temperature over than 315degC or when PWHT is required. my questions is why not allowed?
