Mounting sampling pipe
2.5.1
General information
Mounting and installation is based on the “Planning” section in technical description T 131 192. Deviating from the layout of the
sampling pipe and sampling holes (also outside the limits calculated with “ASD PipeFlow”) is permissible only with the consent
of the manufacturer.
The sampling pipe can be hard PVC or halogen-free ABS material, depending on requirements. In special applications (e.g. in
an extremely corrosive environment) other pipe materials may be used subject to the specifications in Sec.
Notice about pipe installation / modification
The performance of this system is dependent upon the sampling pipe. Any extensions or modifications to the de-
signed installation may cause improper operation. The operational effects of such changes shall be verified. Sec-
tion “Planning” (T 131 192) must be considered in any case.
The calculation software “ASD PipeFlow” is available
from the manufacturer.
2.5.2
Mounting with PVC tubes and fittings
As a rule, when the installation operator does not demand halogen-free installation, sampling pipe can be laid out with hard
PVC tubing. When PVC tube material is installed, the individual tube parts are glued together with a special PVC glue (e.g.
Tangit for PVC). The glue manufacturer’s instructions must be followed. Before gluing, use household paper to remove dust
and grease deposits from the surfaces to be glued (do not use textile cloths). If the tube parts are very dirty, a cleaning agent
specified by the glue manufacturer may have to be used.
Notices
•
The adhesives and cleaning agents used for connecting PVC materials contain solvents and are combustible.
For this reason, prior to working with these materials it is imperative to read and observe the safety instruc-
tions and information provided by the adhesive supplier.
•
The two glueable materials – PVC and ABS – must not be combined, since different adhesives are used.
2.5.3
Mounting with ABS tubes and fittings
If required, halogen-free ABS material can be used for the sampling pipe. When ABS pipe material is installed, the individual
tube parts are glued together with a special ABS glue (e.g. Tangit for ABS). The glue manufacturer’s instructions must be fol-
lowed. Before gluing, use household paper to remove dust and grease deposits from the surfaces to be glued (do not use tex-
tile cloths). If the tube parts are very dirty, a cleaning agent specified by the glue manufacturer may have to be used.
