3.1.3 Selecting the flanges with tube
The criteria listed under  p. 28, 2.3.2 are applicable for selection.
Inside coated ducts
The following points must also be taken into account when the inside of the duct/pipeline
is coated (rubber insulation):
● Since the inside of the flange tubes also has to be coated, it might be necessary to
select flange tubes with a larger inside diameter. The minimum distance between the
probe tube and flange tube is 3 mm.
● If a standard flange with tube cannot be used, make the flanges with tube onsite (deliv-
erable by SICK on request).
● To ensure coating is complete, the flanges must be mounted before being coated.
Plastic ducts
The standard flanges with tube generally cannot be used for plastic ducts/pipelines.
Possible solutions (to be carried out onsite):
● On GRP ducts
1:
Laminate the steel core with pitch diameter of the mounting holes. The
inside diameter of the laminated flange tube must match the selected FLSE100.
● Use flanges with tube made from duct/pipe material; weld-mount or fit with plastic
adhesive.
● Mount adapter flanges on openings prepared onsite.
Determining the nominal length
The required nominal length of the flanges with tube can be determined using the following
Figures.
