Dear David339933, Thank you for your reply. Our Vessel [highlight #FCE94F](Operating Pressure 0.1Kg/Sq.cm)[/highlight] don't have Long seam and Cir seam weld. It is actually a Rectangle vessel with Corner Joints and Fillet weld only. Suggested by our Welding Engineer to use ER80S-B2 with...

Dear r6155, Jacket Operating pressure will be 3 Kg/ Sq.Cm and Design Pressure will be 5 Kg/Sq.Cm. Jacket side operating fluid is Hot water.

Dear Ironic Metallrgist, Thank you for your reply. Noted the contents. This is not the coded job. As you said i already sent out the welder who did this mistake. I though unable to remove all the weld metal out since it already mixed with the parent metal. If i removed the existing...

Dear DHURJATI SEN, This is actually the Jacket End closer plate of the vessel. Both side of the Jacket and Closure plate (MOC 16 Gr.70) will have 30 Deg. Chamfer and welded with the E309Lmo filler instead ER 70S 2. Jacket side operating fluid is Hot water. Hope this information will help you to...

Hello all, Please tell us any problem when using 309LMo filler to weld SA 516 Gr.70 plate to SA 516 Gr.70. This because the welder unknowingly welded the job using E309LMo filler. This weld needs to removed or else leave it as it . Awaiting experts advises.

I taken all your advices to contract a welding experts. Meanwhile please let clarify what is wrong in my selection of electrodes, code exemptions of PWHT etc. will help me more, Thank you..

Thank you all for your responses. (a) Except for exemptions in General Note (b), postweld heat treatment is mandatory under the following conditions: Please clarify the point (a). Except for exemptions in general note (b) PWHT is mandate for P4. So I thought that according to Note (b) I can...

If we meet these conditions as per UCS 56 P.No.4 Note (b)1,2,3 can we neglect the PWHT. If we do the PQR to be passed without PWHT can proceed the job without PWHT.

Seen the Code UCS-56 Note (b)1,2,3 says PWHT not manditory when meeting the following conditions. I.e, Thk.16mm Max, Carbon Max .015 and Preheat 120Deg C. Oue Base metal Thick is 12mm. GENERAL NOTES: (a) Except for exemptions in General Note (b), postweld heat treatment is mandatory under the...

Is Cold forming recommended for annealed 410 materials.?? I did the trial dish with preheated up to 150 deg C and got the formed dish end without any failures.. So I concluded that the cold forming is wrong for 410 annealed plates. Whats your thoughts here please..

Hello all, Based on review of technical articles I choosed ER80SB2 and E8018B2 with preheating of 160 Deg C. As per UCS 56 less than 16mm no need of PWHT. Not yet did the PQR since the vessel is in design stage. My question is am I choosed the correct electode. Or I need to choose Er70sB2L to...

Thank you all for your much valuable responses. Is Cold forming recommended for annealed 410 materials.??

It's cold formed since the material was annealed condition...

Hello all, Recently we sent the dish blank for forming operation. While forming the dish end, the base material was broken up to 1 feet from 4 inch away from the weld joint. The condition of received plate was HOT ROLLED, ANNEALED AND PICKLED. Plate Thk.10mm. Welding consumable used E309/E309L...

Hello all, Recently we got an order to manufacture the reacter vessel . Material Sa 387 Grade 11 class 2. Manufacturing code as per ASME Sec 8 Div.1. Request all to give suitable welding consumable, preheat and post weld HT requirements of this material. Thickness of the plate 12mm. Thank you...
