5.2 Installation instructions for welding
(refer to Fig. 3 page 5)
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 flat gasket
(Pos. 17). The heat-affected zone should be restricted to the immediate weld seam area!
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
The controller is set by the manufacturer as stated in the order and does not need
changing. Should the operating parameters have changed fundamentally compared with
the particulars in the order, please contact the manufacturer to change the controller!
5.4 Steam trap testing through ultrasonic measurement
Testing the operation of the steam trap in the installed state is straightforward with the
“ARImetec
®
-S” mulitfunctional testing device.
Refer to data sheet “ARImetec
®
-S”.
5.5 Installation position
(refer to Fig. 6 and Fig. 7 page 12)
The float steam trap can be installed for vertical or horizontal flow. This should be stated
when ordering.
If the installation position is not stated it will be supplied for vertical flow.
It is possible to change the installation position at a later stage (see 7.2).
However the steam trap must always be installed so that the ball float (Pos. 24.16) can
work in a vertical plane.
ATTENTION !
The vent tube (Pos. 24.12) must point up!
