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 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.

this is new vessel. and also we did PWHT only one times but it was burned during PWHT exceeding temperature 650 Deg.C

Please go into following engineering website http://www.pes21.com you may calculate trunnion lifting lug .

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.

As per UCS56 in ASME, less than 13mm throut length of weld , PWHT is not required, but Client is asking for PWHT and Hydro test again due to precess requirement. Process requirement is only for NACE and Sour service as we know.

this vessel is not rewuired ASME code STAMP. Is it also required Local PWHT and Hydro test again.?

For the additional information, this vessel material is of A516-70, and Design temp is 160 Deg. C, Process condition is NACE and Sour service for this vessel. This internal stiffener was attached after PWHT and Hydro Test, and then this stifferner was removed again by Grinding.

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...

When I review this case in details, we have to consider why we have to hydro test after welding. The purpose is to verify leakage on surface of vessel. However, when we need additiona welding Vessel Long or Cir or nozzle as penetrated welding, Absolutely, in this case, this carbon vessel should...

Hello ! Following web address, you may find reference for Trunnion type lifting lug. http://www.pes21.com/home_56/engineering_web/str_lug_trunnion_9_V.asp www.pes21.com

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.

Hello ! I'm not sure about compress soft ware is available for nozzle load calculation with WRC 107 for the nozzle on Top head (Bliend Cover). Could you let me know how to input nozzle load in this case.

Hi compress user all I have a quick question, Is it available to check hill side nozzle opening in Compress program.

Hi Reinforce pad calculation in pressure vessel will be figured at following website. http://www.pes21.com

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...
