5.2.1 Installation instructions for welding
Please note that only qualified persons using appropriate equipment and working in
accordance with the generally accepted rules of sound engineering practice are allowed to
install valves by welding.
The plant operator is responsible for ensuring that this is the case.
Refer to the data sheet for information about the form of connection as well as instructions
for welding socket and butt weld ends.
All products welded into the piping system should be adequately cooled to prevent any
adverse effects on the sensor or damage to sealing rings. The heat-affected zone should
be restricted to the immediate weld seam area!
For pre- and post-welding heat treatment, refer to the material specification sheet in DIN
EN 10222!
