    Pipeline transporting Naphta and jet fuel

    No argument there. Outside the US, there may not be any meaningful distinction between pipelines and process lines. And, if it were a short bit of above ground pipe in what was a long buried pipeline, I would definitely not change the code. Inside the US, there is a clear difference that...

    US REFINERIES CANNOT PROCESS LITE OIL

    You are going to be BUSY. I just don't like the looks of this site. Just another Google document.

    Pipeline transporting Naphta and jet fuel

    There are hundreds., if not thousands of miles of B31. 4 &. 8 above ground pipelines in the world. What matters is if it is a pipeline, or a process line. Look in the Scope 1.0 of each code for their definitions and select the code that applies.

    US REFINERIES CANNOT PROCESS LITE OIL

    Yes, still having fun. Extremely happy I am living here. I turned off the USA news feeds and I've been working, more on my paintings. With the long holidays here running into January, several of the better fiestas in late Jan and early Carnival, time goes into warp drive. I have also been...

    US REFINERIES CANNOT PROCESS LITE OIL

    If anyone is interested, this video explains the various crude benchmark futures price spreads and their relationships to their geographic delivery points and transportation costs. I am not sure what process engineering expertise he has, but he does mention that a Shell refinery in Mississippi...

    US REFINERIES CANNOT PROCESS LITE OIL

    The thing I keep seeing on you tube is that US refineries must export light shale oil to refine it in other countries. I have discussed this at length with several AI LLMs delving quite deeply into process constraints of various refinery configurations and in general this does not appear to be...

    Underground Oil & Water Pipelines

    I believe he said external corrosion, so probably a pinhole or scratch, or poor wrap in the coating. It is unusual, but not unknown to happen within 6mo of installation, especially in acidic, wet soils.

    B31.8 Location Design Factor Change

    Does B31.8 actually require that you subtract undertolerence from the wall thickness? I don't have a new version of B31.8, but old versions do not require that you consider undertolerence. That is already considered in the DF.

    Can we PLEASE go back to the old forum!

    Are you f kidding me. It don't fly. If I wanted Redit, I'd be at Redit. How do I delete my membership? In fact I may not return to find out how. If I ghost you, you know why.

    Nitrogen Leak Test on a Pipe

    Higher N2 pressure cylinders are common. UN/ISO Nitrogen Storage Tank: 424 cu ft, 4500 psi No compressor required. --Einstein gave the same test to students every year. When asked why he would do something like that, "Because the answers had changed."

    Question regarding aluminum design manual 2020

    I don't know that code. Some context of what you are trying to do would help. Anyway try this and see if one of these fits your situation. Torsional Constant And Torsional Shear Constant. http://dir.cisc-icca.ca/files/technical/techdocs/updates/torsionprop.pdf --Einstein gave the same test...

    Looking for threads relating to best practice/calcs for building temporary supports for mobile struc

    There I can tell you a little something anyway. Use some simple static calculations for a billboard at height. Say you have a wind load at a center of pressure 5m above your supporting points. Wind Overturning Moment = Wind Force x height 4000N x 5m =20,000 Nm Weight = 2000N If resisted by...

    Looking for threads relating to best practice/calcs for building temporary supports for mobile struc

    I've seen lots of strange looking things in the deserts. Seldom can you trust that anything will be built to what you are accustomed to seeing and level floors are not high priority. Generally, if the bathrooms have running water and lights come on, you won the battle. Most of us here tend to...
