    Bend Test for Aluminum Bronze

    We are preparing a PQR for welding Aluminum bronze and I am unsure if this material is too brittle to get face and root bends. We have materials for one "testing" and I am outside of USA and can't replace soon. Did anyone else have any luck with this and is there some justification to do...

    Parallel Tailing Beam/Skirt Stiffening Beam Internal Moment Coefficient Kr and Kt

    AutoPIPE Vessel uses internal tables and FEA-backed data, It's a proprietary FEA-based database for support configurations. I suppose you could validate using Roaks, maybe if you share some details i can check in solid sim

    External Pressure Stiffner Ring

    Agree, How would you test and inspect this governing weld without access for visual... Can you share some dimensions and design conditions. I would like to run it by Compress and see what comes out. is there no way to relocate away from weld say 2in using another size or stiffener configuration?

    ISO Tanker Repairs Code and Inspection body

    Good day, We have to repair an ISO Tanker used to store Nitrogen. There are no issues with the teel frame just a lean on the outer shell. What code or certification body would best be suited for this work? ASME R, API 50 or some DNV spec?

    Overlapping limits of reinforcement between nozzles N1 and N2 detected - user intervention may be required

    Sharing my 2 cents on this deficency as there isnt much open documentation on the matter. My understanding is that the software is asking for the designer to use their discretion to resolve an 'imaginary" discrepancy, where the program is using binary, 2d logic against a physical issue. rather...

    Plate marking as per SA-480

    Speak with your AI. I would recommend you get a letter from the MILL via your supplier grating permission to mark the plate with the following: MFG logo (SSAB/Nucor etc) 2. Material grade/Spec/Edition (ASTM – 17 Accepted) 3. Heat number 4. ID # if applicable 5. Heat Treatment (Norm/MT)...

    Head Joint Design for UL 142 Tanks

    Good day All, We are currently evaluating a build/buy for a UL 148 Diesel Tank. We are not located in USA so local fabrication may be significantly cheaper. The tank volume is less that 1000 Gallons and I was wondering if we need to use heads or can use flat plates for the endcaps. In...

    AWS 5.01 Requirements for reviewing Filler Metal Supplier Quality Program

    I am reviewing AWS 5.01 Procurement Guidelines for filler Metal for the purpose of Section 8 compliance. I noticed that A 1 . 2 states that "it is the responsibility of the purchaser to review the quality program of the manufacturer " Does that mean I have to reach out to Lincoln or Weld Wire...

    What method of analysis is used to validate an offshore vessel is structurally sound?

    Howdie Structurally inclined friends. We are replacing an offshore separator, and our client wants us to run some type of additional structural analysis using their measured spectral accelerations. As is, we are accustomed to using ASCE-7 and our software Compress is set up for this. This...

    How is sloshing accounted for in Pressure Vessels Seismic Considerations?

    How is sloshing accounted for in Pressure Vessels Seismic Considerations? Does ASME VIII cover it directly?

    Leak seal welding for TTS expansion joint

    is your concern about welding copper nickel material particularly? If tubes are closely packed together then seal welding is usually required. I don't have a copy of TEMA but clients ask for it. The weld will protect the mechanical joint created by the expansion process and assist with heat...

    What seismic codes should be used for Vessels to be installed on Offshore Platforms?

    I am unsure if ASCE-7 is more suitable for onshore usage and if there is some ISO or API standard that are more suitable for this end case. I am totally ignorant or Norwegian or European codes, I'm not sure if they would be relevant to US companies either. Any advice on standards, or should...

    Hydro Test with Different Pressure Application for Shell and Tube Side

    Does TEMA cover this? My organization only has ASME codes and as another comment mentions UG-19 2 which discusses this. I would check the HXcher bible for more in depth advice.

    ASME CODE STUDY STRATEGY.

    Thank you for this great advice , I find Megyesy more useful as a lookup reference and Moss more interesting. I also want to add the Metalic Vessel fabrication guide from Wiley press to the list of reading.
