Axial expansion of Stainless Steel Tubing 1

[dawg22]

I would like to know how much axial expansion (inches or mm) that I can expect from 12" dia. schedule 40, 304 and 316 Stainless steel tubing when continuously exposed to 210F. Could I get a formula?

Hi dawg22

length * coeff of linear expansion of steel * temp change =

change in length.


temp change is the difference between normal room temperature and the temperature your tubes working at.


In degrees centigrade the expansion for a metre length will be:-


1m * 12 * 10^-6 * (99-20)= 9.48 * 10^-4 or 0.948mm

dawg...

There are very useful tables on the expansion of SS,CS and other materials in the Appendices to ASME B31.1 and B31.3

Excellent reference....
