thermal expansion calculation (onshore)

[olaeng]

goodday everybody,

i will like to know the procedure to calculate the pipeline thermal expansion of an onshore pipeline and also the allowable bending stress.

thanks

Hi olaeng

The pipe line expansion is given by:-

pipe line length * coeff of expansion * temperature change

But in order to help you further I would like to know more details about the pipe line.

For thermal stress, once you have thermal expansion above, multiply by Young's modulus.

Bending stress = Bending Moment/Section_Modulus
