    Corrosion between SS316 and Duplex 32205

    The plug we usually use are rubber expanding plug done at SS316 but in this case we are not sure use SS316 plug with duplex tube.

    Corrosion between SS316 and Duplex 32205

    Thanks for your answer EdStainless. This will be a mechanical Joint. It is to plug (316) a tube (duplex). Do you know where can I find a table for Galvanic potential where appears the duplex 32205? Regards.

    Corrosion between SS316 and Duplex 32205

    Dear All, I am trying to find the Galvanic potential of the duplex 32205 respect SS316L. Anyone can help to find it? We need to know if would be corrosion if duplex 32205 and SS316L are in contact and we have to justify. Thanks.

    Problem creating a steel transmission pole

    Hello, I am modelling a steel transmission pole in solid works to analyze some holes we have to do at grounding level. I try to create de pole from a sketch of 2 octagons and then extrude but I can’t get it. I create doing first and extrude from de octagon and then make a new sketch and make a...

    Double angle section

    I just discover that 12 is the equivalence between feet and inches, 1ft=12in

    Double angle section

    Hello, I am calculating a double-angle sections for a bracing member in a steel lattice tower. My doubt is when I calculate de distance (a) between connections. Acording the formula in AISC Section E6.2 I have read that the distance is equal to effective length divided by the number of spaces...

    Bolts doubt

    Thanks a lot. We also do. This time was the first time I heard.

    Bolts doubt

    Thanks for your answer. My doubt is that one client say us that is not recommendable use bolts 8.8 (equivalent more or less to T1) in the steel lattice towers. In my opinion there are no problem when you check the PLS-TOWER output and everything is under the limit the calculation are OK. Is...

    Bolts doubt

    Hello, I have just talking with a costumer about the use of different quality bolts. In Europe case 5.6 Vs 8.8 (according ISO 898-1) and in US case T0 Vs T1 (according ASTM A394) I think with steel S275 and S355 (Europe) or A36 and A572 Grade 50. The question is that he explain me that is not...

    Design of steel pole ASCE/SEI 48/11

    I did an approximate calculation and I have obtained the Compression, bending and combined Stress according ASCE. For compression and bending I have more ore less normal efforts but in the combined stress the value is too high. I attached the spredsheet I have done, is very simple. Maybe I have...

    Design of steel pole ASCE/SEI 48/11

    Thank you for your answer transmissiontowers, I know how PLS-POLE works. I have used in my previous work. What I would like to do is calculate the pole by hand and later compare with PLS-POLE when we buy.

    Design of steel pole ASCE/SEI 48/11

    I hope you could help me. We are thinking in buy PLS-POLE to redesign our steel transmission (octagonal) poles. They are form 90's. But first I want to learn how calculate manually in order to use correctly PLS-POLE. We have bought ASCE /SEI 48-11. And after read it carefully I have some doubts...

    Modeling an octogonal pole

    I forgot show my mesh.http://files.engineering.com/getfile.aspx?folder=17e9cb8b-db33-4291-9a4c-46f78a2b11ce&file=octopole_mesh.jpg

    Modeling an octogonal pole

    According my model I should round the corners of the pole because of the difference between the perfect model in NX and the reality when you manufacture. I have mesh wiht CTETRA(4) tool, do you think is right? With this way my octopole is perfect to fix de areas I want. When I use CTETRA(10) I...

    Modeling an octogonal pole

    Great solution carlharr, It is just what I need but in order to resolve the analysis I need to fix a pole in an imaginary line in the middle in the hole. As if the pole is buried in concrete. I have made my model with and extrusion and later making a shell. In my model when I messh I can't...

    Modeling an octogonal pole

    One thing more. I need to have a constant thickness in the pole.

    Modeling an octogonal pole

    Dear All, thank you very much for your help. All your comments have been very useful. MustafaAsan It is just what I want. I have done one just like these but I have problems when I mesh. I can’t select the right surface to fix the restrictions. Toost It is exactly what I try to do. I will try...

    Modeling an octogonal pole

    Dear All, I am trying to model an octagonal pole for electric distribution. I have made by different ways but I want to know if it is possible make an extrusion with taper. What I want to do is draw the base octagon (inner and outside) and the same in other plane with the top of the pole. And...
