Dear sir,
Could you please tell me what is weld edges in RCC-M Nuclear standards?
In case of butt weld for piping, I understad that the bevel of pipe is weld edges.
In case of set on pipe weld between pipe and casing, the bevel is prepared on the pipe, but not on the casing.
In case of this...
Dear all
Thank you for your reply.
I see NB-370 and almost state require ASME.
So I cofirm it to ANI.
THe following is tank spec.
Press: 0.98 MPa
Temp:-253℃~+40℃
Dear sir
Does anyone know the literature on hardness distribution from the surface to the inside of the haz part of martensitic welds? I'm in trouble because the surface is abnormally hard and I don't understand the reason.
Dear sir,
If we supply the LH2 strage tank for liquid hydrogen station of car in USA, Dose we need to get ASME-U STAMP in order to maufacture the tank?
(or is necessity of ASME-U decided as per state law?[for exsample, California is needed, but Florida is notneeded])
Could you please advise me.
Hi
Could anyone please tell me the following.
We are confirming the CASTING CA6NM MMmanufacturing procedure.
in the doc., welding process is conducted before quenching and tempering as material heattreatment.
in this case, Should we include quenching and tempering on WPS as PWHT?
Dear sir,
Please kindly tell me about NB 6115 machining after prresure test.
if permanent deformation is occured by the test, we can performe mhachining the surface in order to fix the crutical dimension as per NB6155?
My understand is that NB 6155 is not accept permanent deformation.

Dear all,
Thanks all for several comments.
For more discussion, Please kindly see attached photo as welding joint form.
This joint is such as olet weld(Pipe to Pipe/ Pipe to shell) and
This portion is changing thickness.
I understand that it is difficult to perform RT on changing thickness...
Dear r6155,
thank you for reply.
Now, I am planning to prepare the procedure for UT in stead of UT.
But, I think it is difficult to perform UT/RT on entire volume of welding(that is 100% volumetric inspection.)
Of course, I am planning to inform the customer of this problem and
discuss to solve...
Dear all,
I am requested to perform volumetric inspectin(RT) on full penetration corner weld(not butt) such as category D weld(weld to flange and shell) ASME SEC.VIII DIV.2 by customer.
But as mentionded on some standard(ASME SEC.VIII div.1,2 , ASME B31.3),
it is difficult to perform RT on this...
