Thermal changes in length

Heating and cooling cause pipe length changes. The coefficient of expansion of DUOPEX GAS composite pipes is 0.026 mm/m x k

Thermal changes in length	Example Temperature
Pipe length changes are caused by heating and cooling. The coefficient of expansion of DUOPEX composite pipes is 0.026mm/m x K.	differential ΔT	50 K
	Pipe length L	5 m
	Coefficient of expansion a	0.026 mm/m.K
	Linear expansion  ΔL	6.5 mm
	ΔL	= a x L x ΔT = 0.0026mm/m . K x 5 m x 50 K = 6.5 mm
