when calculating the changes in length to the pipe
caused by fluctuations in the temperature, the
following points must be observed:
1. Assembly or installation temperature
(e.g. environmental temperature)
2. Temperature of the media in the pipeline
Determining the change in length
The change in length is determined as follows:
∆ L = change in length mm
L = length of the pipe to be calculated m
∆ T = difference in temperature between the
temperature of the media and the
installation temperature K
α = length expansion coefficient mm/m * K
Formula: ∆ L = L x T x α
Expansion coefficients specific to the material:
PVC 0.08 mm/mK
PE 0.20 mm/mK
PP 0.15 mm/mK
PVDF 0.12 mm /mK
Stainless steel 0.0165 mm /mK
Steel (Fe) 0,0120 mm/mK
