Thermal expansions and contraction

Thermal expansions and contraction

(OP)
Is there any thumb rule available for knowing the thermal expansion or contraction (directly propprtional to length and delta T) of routed cs, ss pipes because in 31.3 tables are for mm/100 ft and that also as per temperatures.

RE: Thermal expansions and contraction

There is no rule of thumb.  It is a simple mathmetical calculation based on the coefficient of expansion for the material, the length and the temperature difference.

Yes inshort I need a thermal expansion coefficient of CS and SS based on delta temp.

Sachin

RE: Thermal expansions and contraction

Google "thermal expansion of metals"

α CS = 6.5 x 10-6 in/in-Fº
