RE: [MW:6616] Simulation of Carbon Steel Dished End Normalised After Forming

Simulation of all anticipated heattreatments are required, ln general N+2SR are sufficient, unless client has specific requirement for provision for inservice repair, if any.

Subject: [MW:6615] Simulation of Carbon Steel Dished End Normalised After Forming

Dear All,

I have Carbon Steel Dished End in which Normalising is required after
forming as per customer specifications.The thickness is 28mm due to
hydrogen service PWHT is required for 60minutes.

My Questions:

1. As the material is carbon steel and simulation is required as per
UCS 85(f), because my material is going above lower transformation
temperature. What should be the simulation cycle?

Do i need to give the SR cycle in simulation? i mean simulation of N
+SR

2. and if i have the simulation available N+SR, and i need to Re SR
the job due to shop repair. Do i need the simulation N+SR+SR or the
simulation available above is OK.

Regards
