    Expansion pipe loops and its guide supports

    Hello everyone, I've reading some info about how to pipe size loops herein however it seems that there are no defined rules to do it. 1) some people say the leg of loop should be H=2W, where H is height and w=whith; 2)others say H=W; 3)also each guide near to loop have a distance of W...

    API-650 - Max. Loads on Tank Shell Openings

    Hello everyone, following the messages above, I have run the analysis bellow: 1)Created a piping system; 2)Define a tank diameter above 36m and its nozzles connections; 3)Run the analysis. Took the radial force, the circunf. and the longitudinal moments; 4)Ploted that figures in the...

    API-650 nomographs & CAESAR II

    Do we really need to construct the nomographs shown in API-650, Appendix P? CAESAR II gives automatically the allowed radial force, and the allowed circunferencial and longitudinal moments. So after run the piping flexibility analysis we just need to compare the values above mentioned with...

    API-650 - Max. Loads on Tank Shell Openings

    According API-650, Appendix P, the procedure should only be used to tanks larger than 36 m in diameter. But I think if you define a smaller diameter in the API-650 nozzle routine (in Caesar II) the analysis will be the same.

    API-650

    Hello everyone, I am currently analysing appendix P of API-650, once I have to calculate the allowable external loads on tank connections. However this API only describe a method to tanks larger than 36 m in diameter. Please could anyone tell me how should I procede for tanks smaller than 36...

    API-650 - Max. Loads on Tank Shell Openings

    Hello everyone, I'm modeling a piping system where I have to know the loads on a tank nozzle due to the piping connection. The model is defined as well as the data for the type of tank and nozzle, so that CAESAR II can give me the maximum allowable loads, stiffness coefficients and its...
