MOUNTING AND PLANNING INSTRUCTIONS
The approaching flow causes the protective tube to vibrate.
If the specified approach velocity is exceeded even by a marginal amount, a negative impact on the protective tube's service life may result (material fatigue).
Please observe the permissible approach velocities for stainless steel protective tubes (see graph TH-VA) as well as for brass protective tubes (see graph TH-ms).
Discharge of gases and pressure surges must be avoided as they have a negative impact on the service life or may damage the protective tubes irreparably.
