Coping Calculator for large steel pipes in Excel format

This Coping Calculator is a handy tool that I use to create flat patterns for different pipes cuts, includes miter cut, pipes intersecting with variable angles or a pipe piercing through another pipe.

The Excel spreadsheet includes all configurations with a graph/flat pattern that looks like a bell curve. Just input the diameter and wall thickness, or angle of intersection.

Also included a Visual Basic (.dvb) program for Autocad that will take points from the Excel spread sheet and plot a flat pattern curve directly to Autocad.

    Thanks Johnny, OD is the input, also the equations in the spreadsheet considers the wall thickness for the output data.

    I am trying to cope some 8" XS pipe as shown in the attached "cope.pdf". Would anyone care to share a few pointers with me? Advance thanks!

    Jay,
    I think the obvious solution is offset the diagonal pipes so it doesn't intersect with the vertical pipe. Although if you must have this configuration of intersecting pipes then I would say the diagonal pipes you could use the spreadsheet to create 2 curves at 180 deg (not the 360 deg) one at 36.93 deg and the second at 53.07 deg then splice them together for a full 360 deg flat pattern curve. This is not easy but with a little attention to detail I think it can be done. Good luck!
