5.1 Welding Instructions
- Welding shall only be carried out by certified welders (EN 287 - 1).
(seam quality EN 25817 ,,B”).
- The welding of the mating flanges must be undertaken in such a way
that deformation strain cannot arise.
- TIG orbital welding is the most appropriate method!
- Before welding, all sensitive parts must be removed!
Dismantle the valve core with seals, etc. from the mating flanges.
- After welding of the mating flanges and after work at the pipelines,
the corresponding parts of the installation and pipelines must be
cleaned from welding residues and soiling.
If these cleaning instructions are not observed, welding residues
and dirt particles can settle in the valve and cause damage or be
carried over to other parts of the installation.
- Any damage resulting from the non-observance of these welding
instructions is not subject to our guarantee.
