Dear sir,
I have a quick question.
What is different between material is produced to fine grain practice and not defined fine grain practice.
Is there any physical changes in ASME code calculation.
Your quick response will be appreciated

Dear guys,
We are in a very difficult situation,
One of the Vessel (ID 3000, Shell Thk 35mm, SA516-70N) was over heated over around 800 Deg. C during PWHT for exceeding PWHT temp (650 Deg. C)
The result of this accident, mechanical proporties of vessel material come out to be reduced by 10%...
Dear sir,
When we need to segment reinforcement pad, please define whether we have to R/T and require welding efficiency F=1
as we know, ASME not define NDE requirement on this.
Dear Engineers
I have a quck question about additional wleding after PWHT
and Hydro test completely.
present situation is as follows.
In a vertical pressure vessel of ID3000mm, shell Thk 17mm
herewith, one of Internal supporter (T10mm x 50mm) was attached with 8mm fillet welding and then...
Dear sir,
I have a queries on name plate of pressure vessel
without Code stamping.
Usually we attach name plate in the name of supplier of fabrication.
However, when we supply vessel equipment through sub-contactor who is incharge of fabrication of vessel.
In this case, our name plate is to be...
I have a queries on whether it is permissible to do welding of small of pipe support clip on vessel with only fillet welding after completion of shop hydrostatic test.
Hello !
I'm in a very difficult situation to do calculation of reinforcement area in common pad between Two nozzle, this case is not subject to multi- opening requirement as per UG-42.
the result of my calculation is follows.
- Required area : 0.5*d*tr in a single opening case
- Available area...
Please let me know how to input nozzle load in a case of Nozzle stress in WRC107 on Top cover (Blind Cover Head)
Is it available for this calculation in compress soft ware.
We are asked to define reforcement calcualtion for the 3"-SCH.160 size of the nozzle opening in Flat Cover (Bliend Cover (OD 600mm, Thk 140mm)
As per UG39, this is available when nozzle diameter should one forth of Bliend cover.
Please confirm this requirement whether 3" nozzle should be checked...
