Boiler stainless steel

PCVS society designs and implements pressure equipments, according to codes: ASME, CODAP and EN13445.
Our main achievements are tray columns (or other type of packing) reactor shell or double envelope (with stirrer or not), simple or double envelope tanks and any type of tubular exchangers (simple or double tubesheet, floating-head, AET or AES, U tube…).
We also have many references in clades steels (Weld overlay).

Our workshops are equipped with stainless steel boiler a machinery High Performance
