5.2 Installation instructions for welding
(refer to Fig. 6 page 5 and Fig. 8 - Fig. 10 page 6)
Please note that only qualified persons using appropriate equipment and working in
accordance with technical rules are allowed to install fittings by welding.
The responsibility for this lies with the system owner.
Please refer to the catalogue sheet for information on type and instructions relating to
welding socket weld ends/butt weld ends.
When welding products to the pipeline system they should be adequately cooled to prevent
any adverse effect on the complete controller assembly (pos. 24) or possibly the sealing
ring (pos. 26). The heat-affected zone should be restricted to the immediate weld seam
area!
At face-to-face dimension 95mm, and also at nominal pressures PN63-630 before welding
or stress relief annealing, the controllers have to be extended (see 7.1).
Note pre- and post-welding heat treatment in accordance with Material Fact Sheet
DIN EN 10222.
If there are plans to acid clean the facility before putting it into operation, the controllers
(pos. 24) should be dismantled completely, replaced by acid cleaning inserts, and
reassembled after acid cleaning (see 7.1). In such an event please contact the
manufacturer.
5.3 Controller adjustment
ATTENTION !
- refer to item 10.0 and 11.0 prior to dismantling and repair work!
