steel pipe expands at .0000067 per deg. per foot example a steel pipe 100 ft.long at 30F when heated to 80F will be EL=expansion length L1=original length t2-t1=temp change CE=coefficient of expansion L2=final length EL=100(80-30)x.0000067 100x50x.0000067=.0335 or 3/8" (approx.) L2=100ft. 3/8in.
Pipeline thermal expansion elongation of the formula:
Where: linear expansion coefficient of carbon steel 12X10-6 / ℃
△ L = (t1-t2) L
△ L- pipe thermal expansion elongation (m) - medium temperature (℃) linear expansion coefficient of carbon steel 12X10-6 / ℃ t1- pipeline running temperature (℃) t2- during pipeline installation, L- computing length (m) pipe section
△ L = a (t1-t2) L a-- linear expansion coefficient of carbon steel 12X10-6 / ℃

CTE, linear 20°C 16.9 µm/m-°C 0 to 100°C
CTE, linear 20°C 18.7 µm/m-°C to 649°C
and 316L:
CTE, linear 20°C 16 µm/m-°C 0 to 100°C
CTE, linear 20°C 19.9 µm/m-°C to 871°C
if you want better CTE in an oxygen free environment, try carbon fibre (-1 to +1 µm/m-°C, parallel measurement). Or 'till 450°C at normal atmosphere.

All material expansion coefficientsare in length/length/Celsius or length/lenghth/Fahrenheit; i.e units of 1/C or 1/F
For example, steel may be 17E-06/C ( m\m/C)
the length unis make no differnceas they cancel out: in/in or m/m, etc.
To convert from C to F divide by 1.8
For series 300 (18-8) austenitic stainless, expansion is 16.9 ppm/C.
For the less common 400 series ( Martensitic) , expansion is about 10.0 ppm/C
ppm = parts per million; C =celsius; for F (Fahrenheit) divide values by 1.8
6.8x10-6 µin/in-°F for 0-212 F

thermal expansion depends on Temperature and material of steel
Since most metals are isotropic, the cubical coefficient of expansion is three times the linear coefficient of expansion. The linear coefficient of expansion is obtained from measurement and tables for the specific material which are readily available.

Linear expansion apparatus is the apparatus used to measure the objects to these following properties: -> coefficient linear expansion -> coefficient thermal expansion -> specific gravity -> specific heat -> thermal conductivity -> thermal resistivity -> breaking strength and many others..
