CONNECTION SCHEME
|
|
| While preserving the standard assets of manufacture,
the flexibility of the PICKER heat
exchangers range makes
it possible to cover very many configurations of connection
according to the heat balances and requirements of piping. |

fluids
connections :
On the heat exchangers PICKER, connections of the fluids are
carried out according to families' of exchangers :
>
By tapping known as "cylindrical gases" carried out
in the
element and/or the lids (usually for connections until 1"1/4).
>
By counter-flanges of our standard, usually delivered "full" with
joints and screws and bolts (for connections welded, brazed
or
screwed).
With additional charge, the machining of the counter-flanges
can be
carried out by our care (only borings or tapping "cylindrical
gases").
This option must be mentioned with the order by indicating
the
desired diameters.
Draining and purging :
On the heat exchangers PICKER, draining and purging of the
fluids
on the shell side and on the tubes side are ensured by screwed
stoppers in the foundry of the elements and of the lids. |
