Thickness calculation of ovale/obround tube?
Thickness calculation of ovale/obround tube?
(OP)
I have the flowwing problem:
The circular tubes are formed with rolls to have an oval or obround form .. The final form is not circular but obround. My question according to which formula could I calculate the thickness of these tubes ?

How accurate do you think the actual pipes (tubes) will really be made?
How consistent do you think the total group of tubes will be fabricated?

If you are physically running round pipe through a roll and flattening the sides, the exact shape may be rather indeterminate.

@JStephen : it´s obround form but I thinck that App.13 is only for vessel and not for tubes !!
@chicopee : if I use the article for the thickness calculation what about the bend calculation ?
@metengr : Thickness for internal pressure.
here is the coil final form
it will be added to the Heating Boiler

There are no rules that can proof suitability. Proof test is the answer, I believe that is n o other way.

I am not sure how you account for the coil but I would start and solve one bit at a time, so check the wall thickness to begin and try to find what effect the coiling might have and then readjust the thickness if required.

The tube is obround ..und the calculation are according to ASME IV
