isomeric rolling pipe degree calculation formula | How to read rolling pipe direction

In this drawing, the direction of rolling is shown from West to North.

And the dimension given in this is the first dimension which is going towards West, its dimension is 2884.

And the second dimension which is rolling towards North is 2884.

So the dimensions given in this are both equal, so it means that it is rolling at 45° degrees.

If you don’t understand how to calculate it

Then you have to pay attention to which is the first direction and which is the second direction

The second dimension has to be divided by the first dimension

So you can see in the above drawing, both sides have the same dimensions

So you can divide one by the other,

And in the drawing below 👇

You can see that the rolling given is happening from South up

First direction of rolling is 1442 South

Second dimension of rolling is 1700 Up

This is how the direction is given in the drawing

To calculate the degree, what you will do is divide 1700 by 1442

1700 ÷1442 = 1.1789181692

tan‾1( 1.1789181692 = 49.69° degree

After that, you will see inverse tan in your calculator

Select it and add the answer given in it

Then you will get the degree of the pipe

In how many degrees is it

tan‾1( 1700 ÷ 1442 = 49.69° degree

You see that the answer given in this is 49.69° degree

So you have understood What is the method by which the degree is obtained

और दूसरा डायमेंशन है 1700

1700 ÷ 1442 से डिवाइड कर देंगे

1700 ÷ 1442 = 1.1708

49.5° degree

And this is another way through Tan Theta PDF Chart

The first direction of rolling is of 1442 mm dimension

The second direction of rolling is of 1700 mm dimension
