Taper of 1:50
Taper of 1:50
(OP)
Hi friends,
Please help me how to calculate the taper given as 1:50 in a slope is there any method how to calclate the taper.
Thanks in advance!

D = large diameter
d = small diameter
L = length of taper
or
D - d = L/50

Obviously it is a missing piece of information. That is what the equation illustrates.

Metric taper pins are usually 1:50
So d = D - L/48 inch sizes
d = D - L/50 metric sizes
L is length of pin

For example, I have a premium thread of 3/4 TPF (taper per foot)imperial. This means 0.75 inch rise for every 12.0 inches of run ON DIAMETER. The required angle is then 0.5 arctan(0.75/12) = 1.78817 degrees. This would be the standard half angle cone for LTC threads for oilfield casing. API listing is 1 degree 47 min.
You don't need diameter, just the understanding if taper is measured inclusive thereof.
