„Regulations from section: Pipes“ on page 6
Pipelines expand with heat. Heat expansion is dependent on the mate-
rial. Changes in length lead to tension within the installation. These ten-
sions must be equalised with suitable measures.
The following are effective:
n
Fixed and gliding points
n
Expansion equalisation joints (expansion bends)
n
Compensators
