Sumitube Calculator

Sumitube Calculator is a 32 bit Windows program that calculates SUMITUBE and ARMOR start positions and lengths relative to a master tube.

​SUMITUBE* is heat-shrinkable polyoelin tubing designed by Sumitomo Electric. Heat-shrink tubing is used often as protective armor for tube fabrications where there is a possibility that a tube will fail due to friction with other components.

The program can also be used to calculate the positions of spring armor and other types of armor that follow the centerline of a master tube shape.

Major Features

  • Easy entry of the tube and SUMITUBE/ARMOR in the same XYZ grid.

  • Separate diameters for the master tube and each SUMITUBE/ARMOR.

  • Calculates CUT lengths of the master tube (elongation compensated).

  • Calculates CUT lengths of the SUMITUBE or ARMOR sections.

  • Calculates the distance of each SUMITUBE from the end of the tube.

  • Previews and prints reports that display the calculated data.

  • The report includes a dimensioned IMAGE of a straigthened tube with SUMITUBE/ARMOR in place.

  • Use the DATA LIST mode to CUT and PASTE the data to other programs in Windows.

  • Saves and Loads data files to disk.
