Installation
▸
Screw counternuts (8), (9) onto the threaded rod and secure the nozzle at a distance of
approx. 2 mm to the pipeline surface (underlay with uncoated wire).
▸
Align the nozzle so that the marking lines on nozzle and pipe wall are flush and tighten
enough so that the nozzle is pressed against uncoated wire and pipeline surface. Make
sure the nozzle remains aligned correctly.

Fitting the nozzle
▸
Spot-weld the nozzle on the pipeline (seam length approx. 15 mm). Wait at least
1 minute after each welding to allow the seam to cool down before welding the next
point.
▸
Remove uncoated wire.
▸
Unscrew the threaded rod as a whole from the welding aid. To do this, place a wrench on
the counternuts. The centering plate will be removed by the clamp ring.
▸
Finish off the weld seam piece by piece and allow sufficient time for cooling down to
avoid unnecessary strain or distortion on the nozzle and pipe wall.
▸
For cross-duct versions of FLOWSIC100 Flare (F1F-S, F1F-M, F1F-H):
– Determine the distance D1 between outer pipe wall and centering after a sufficient
time for cooling down.
– On cross-duct versions, weld the nozzle on the opposite pipeline side in the same
manner and then determine distance D2.
– Note measures D1 and D2; these measures are required for the geometric
calculation during commissioning.
