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.
