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 / ℃

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.

Boric oxide is added to ordinary glass to increase its thermal resistance and chemical durability. It helps reduce the coefficient of thermal expansion, which makes the glass less likely to shatter when exposed to rapid temperature changes. Boric oxide also improves the glass's resistance to chemicals and weathering.

Materials with a higher coefficient of thermal expansion expand more when heated because they have weaker atomic bonds, allowing the atoms to move more freely and increase in volume. In contrast, materials with a lower coefficient of thermal expansion have stronger atomic bonds, restricting their movement and resulting in less expansion when heated.

The thermal expansion coefficient for hydraulic oil typically ranges from 0.0007 to 0.0008 per degree Celsius. This coefficient represents the change in volume of the hydraulic oil per unit change in temperature. It is important to consider when designing hydraulic systems to account for thermal expansion effects.
