Casing

The casings of the centrifugal blowers from FIMA are welded and have been optimised with respect to the gas flow. Welding seams extending on both sides increase operational reliability while at the same time avoiding crevice corrosion. Pipe fittings with standardized flanges, fas-tight hatches with even sealing surfaces for cleaning or water injection nozzles to avoid incrustations are standard.



The seal between the machined surfaces of the splitted casing is provided through chambered O-rings or flat seals.
Threaded pocket holes prevent fas leaks at the flanged casing joints. The casings are designed in accordance with the European pressure equipment directives.
