reduce thickness of bended copper tubes
We have plans to reduce the thickness of the plain copper tubes, sizes ranges from 1/4" to 3/4" OD x 0.028" (0.71 mm) thickness and we plan to change the thickness to 0.022" (0.55mm) for some reasons. These plain copper tubes used in suction and discharge tube in window air conditioner unit.
I would like to know if these are posible? I would like to know some formulas to calculate if the thickness is possible especially in the bended part since there will be reduction in thickness.
Coul somebody help me regarding this matter.

It would help to know why you are attempting to make the pipe walls smaller.

cost reduction... since we were buying copper tubes per weight we can save at least 18 % to 20 % cost reduction. But before we apply this one we would like check if possible by computation... and also we don't want to create quality problem.

Hope this link helps you somewhat, there is pipe thickness formula info on the BRA factfinder 5 although based on British Standards.
