Compensation vessels

■Overview ■Dimensional drawings

The compensation vessels prevent the level difference which oc- curs with pressure changes in the pressure lines and which fal- sifies the measurement.

2According to DIN 19211, the temperature in the compensation vessel must be assumed to be 50 K less than the steam temper- ature in the pipe when calculating the wall thicknesses. This is because the temperature in the compensation vessel during op- eration can only rise up to the saturated steam temperature.

A material acceptance test certificate A to EN 10204-3.1 is avail- able for the materials from which the compensation vessels are made.
