(OP)
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

RE: thermal expansion calculation (onshore)

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.

RE: thermal expansion calculation (onshore)

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

Bending stress = Bending Moment/Section_Modulus
