5.2 Installation instructions for welding
(refer to Fig. 3 - Fig. 6 page 7)
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. 17). The heat-affected zone should be restricted to the immediate weld seam
area!
If there are plans to etch the facility before putting it into operation, the complete shut-off
valve assembly (pos. 8) should be removed, replaced by etch inserts, and refitted after
etching (see 7.1). In such an event please contact the manufacturer.
5.3 Installation position
Note installation position relative to flow, see mark on valve.
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“.
6.0 Putting the valve into operation
ATTENTION !
- Before putting the valve into operation, check material, pressure, temperature
and direction of flow.
- Regional safety instructions must be adhered to.
- Residues in piping and valves (dirt, weld beads, etc.) inevitably lead to leakage.
- Touching the valve when it is operating at high (> 50 °C) or low (< 0 °C) media
temperatures can cause injury.
Affix warning notice or protective insulation as appropriate!
Before putting a new plant into operation or restarting a plant after repairs or
modification, always make sure that:
- All works has been completed!
- The valve is in the correct position for its function.
- Safety devices have been attached.
