2.3 Welding
2.3.1 Pipe connections
Position the valve inside the vacuum box and secure it
with the mounting tool. The pipe connections for inlet
and outlet can now be welded.
NOTE:
Ensure that the trim internals are removed and
that the mounting flange is the correct size.
For the standard pipe sizes refer to table 7.2 BW (mm).
2.3.2 Welding cover plate (figure 4)
With the mounting tool (4.1) in position tack weld the
cover plate to the vacuum box to secure it‘s position.
Rotating the mounting tool will provide space for the
tack welding.
NOTE:
ensure the valve can move freely and is not
under tension while welding it to the vacuum box.
Damage to trim and trim guiding may occur.
Remove the mounting tool (4:1)and weld the entire
circumference of the cover plate to the vacuum tank.
2.4
Pressure testing
After welding all the valves into the vacuum tank
perform a pressure test with all valves. For this all
valves must be fitted with mounting flanges. This
mounting flange has a dual purpose: firstly it assists
in mounting the valves into the vacuum tank and
secondly to seal the valve at the bonnet connection in
order to pressurize the piping system without the trim
assemblies and actuators mounted.
CAUTION:
Ensure all mounting flanges are in place and
properly tightened. A loose mounting flange cannot
sustain the pressure and will result in unwanted or
unsecure leakage.
2.5 Cleaning
With the mounting flanges in place, clean and purge the
entire piping system with a cleaning media to remove
dirt and welding residues from the system.
2.6
Remove mounting flanges (
Figure 5)
After completing all tests, cleaning and mounting
procedures, remove all mounting flanges (5.1) and
spacer plates (5.2) from the valves. Flowserve Essen
offers a refund system for returning the mounting
flanges and mounting tools after use. For further details
please contact Flowserve Essen Order administration.
