Section 18: Formula for a 45 Degree Conical

Required Information

  • Actual O.D. of pipe Actual O.D. of insulation.71 Weight number

Formulas and Measurements

  • The Apex is the point where the lines meet Multiply the actual O.D. of the pipe times.71.
  • Take the result to the nearest 16th inch, and from the Apex draw a circle Multiply the O.D. of insulation times.71 and with that result, to the nearest 16th inch, draw another circle from the Apex Add for desired ccccrimp and draw that circle Measure 1" to the right of the vertical line and draw a line from that measured point to the Apex Cut lines are the lines obtained in

Procedure

  1. Step 1

    Draw a 90 degree angle. The Apex is the point where the lines meet

  2. Step 2

    Multiply the actual O.D. of the pipe times.71. Take the result to the nearest 16th inch, and from the Apex draw a circle

  3. Step 3

    Multiply the O.D. of insulation times.71 and with that result, to the nearest 16th inch, draw another circle from the Apex

  4. Step 4

    Add for desired ccccrimp and draw that circle

  5. Step 5

    Measure 1" to the right of the vertical line and draw a line from that measured point to the Apex

  6. Step 6

    Cut lines are the lines obtained in
