Hi,
I have questions about the Tube To Tubesheet welds. BPVC Sec. VIII Div.1 UHX not specifies the qualification method so i may use either of groove weld, fillet weld PQR's or Mock-up.(Sec. IX QW-193)
My first question is, which one will you prefer for the attached weld detail? As far as i...

Hi everyone,
Is there any ISO / EN standard or document specific for overlay welder qualification.
If not, any method other than ASME BPVC Sect. IX
Thanks,
I am about to try to qualify a weld overlay procedure to ASME section 9.
Question is, base material has elongation over %20(~25) and the overlay weld metal has below %20 (~15). In this case what will be the bending jig dimensions according to QW-466? Which elongation have to be used to determine...
Hi,
What is the definition of the "Heterogeneous Butt Joint"? I search through the net and find many definitions but none of them clear.
We are welding Armor plates(quenched and tempered, high strength) with austenitic filler(undermatching) and transverse bend tests fails. Because armor plate...
I'm working for a company which provides industrial inspection and testing services. We have EN ISO/IEC 17020 & 17025 accredidation and a working QM system. We are not manufacturing any products.
I have few question about Q1 certification program.
Does a service provider like my company get Q1...

thanks in advance
Hi Everyone,
Is it possible use a PQR(prepared acc. to Sec IX) with EN material S235JR (which is listed in Sec IX table QW/QB422 as P1 material) for manufacturing stamped Sec I Boiler or Sec VIII vessel from P1 material (eg SA516)
Is there any restriction etc.
We need a body flange(App 2 fig 2.4(3a)) and bolted cover for a Div1 vessel with design pressure 3,5 barg@100°C
Can we make(fabricate) this flange(and cover) from plate material and welded in 3 or more segmets. There is some info on hubbed type flanges at 2-2(d) but nothing about ones without...
I need information about davit arm design. Davit shall carry a 30" CL900 blind(~1800kg weight.)used as bolted cover for a vertical vessel. Any help(Company spesific designs, design guides, etc.) will be useful.
Thanks
Hi,
One of our customers wants "jack screws"(how they call but i am not sure that is the correct wording for.)on blind flanges of an U stamped PV. Blinds are varying 3" to 30" and all CL900(RTJ). But they don't provide any details except attached sample.
If i understand correctly, these bolts...
EN 13445 Part3, Section 9, contain information about openins on shells and heads. It seems that there is nothing about nozzle weld configurations or sizing, unlike ASME Div1 UW-16 and UG-41. Is this information given in a different part of the code? at least i couldn't find anything :(
Any help...
Hi to everyone,
In a recent project our client specified a bolted cover as 30" 900# RTJ B16.47B.
When i look trough B16.47 it only specifies RTJ facing for A series. I looked some manufacturer catalogs and find nothing about :(
am I missing something? Every kind of help will be apprecieted.
