Versions for flange shieldings – Rod source with steel cable, one-part or multi-part
– Rod source with shaft core, one-part or multi-part
– Point source with steel cable, one-part
– Point source with shaft core, one-part
Multi-part rod source flange shieldings can be designed such that
they can be loaded with up to 5 rod sources. Signs are attached on
each steel cable or each shaft core. The signs contain information
on
1. the length of the cable for source positioning, if known
2. the source number, e.g. 1860/1-10-08
the source number consists of several components:
1860 is a consecutive serial number
/1 describes the location of the source in the shielding and thus
allows correlation between steel cable or shaft core and source.
The number is to be found on the sign and also on the head of
the shielding (see illustration to the left).
-10-08 indicates the month and year of production (-MM-YY).
The customer has to provide the protection tube for the source; it
should be installed such that the source can be withdrawn any time
without interrupting the production process. The stability of the
protection tube must match the potential mechanical and chemical
stress.
Depending on the dip tube, it may be necessary to adapt the flange
using a flange adapter. If required and ordered, such an adapter
will be included with the shipment. You find the adapter dimensions
in the "Technical Information" in chapter 5. Screws and sealings are
not part of the delivery.
In certain applications it is essential that damage to the dip tube is
detected immediately, so that the source can be secured in time.
Fig. 2-30 and Fig. 2-31 show installation proposals which meet the
highest safety standards. A double-walled protection tube is used;
the space between both walls is filled with protection gas. Any
damage or leak is signaled immediately by a pressure control
switch.
