Drawing Formula of Torispherical Dishend

Step 1

This instruction is given by following ASME code.

Step 1: Draw a line equal to the diameter of shell.

Step 2: Draw the skirt on both end of the diameter.

Step 2

Step 3: Connect the two ends of skirt.

Step 3

Step 4 & 5

Step 4: Calculate the inside corner radius by using following formula.

Icr=0.06 x Inside Diameter of Shell

Step 5:  From one of the ends of skirt draw a circle with a radius equal to icr calculated above.

Step 6

Step 6: This circle cuts the connection line of two ends of skirt at a point name it B. From point B, draw a circle with a radius equal to (shell radius-icr) and draw a vertical line at the midpoint of the line drawn at step 1. This vertical line and the circle will intersect at a point and it is the center point of the dished circle.

Step 7

Step 7: Draw a circle using the center point found in step 6 with the shell radius or dish radius. 

Step 8

Step 8: Draw a circle from point B with a radius equal to icr.

Step 9

Step 9: Trim all the lines except the lines shown in figure beside. 

Step 10

Step 10: Mirror the lines as like figure.



Now you are done & get a ASME standard ToriSpherical Dishend. All the dimension found in this drawing will be ASME standard Torispherical dishend.
