Welded flanges

For the Ecostream cast iron boilers Logano GE315,
GE515 and GE615, special welded flanges are offered to
connect commercially available pipes to the boiler flow
and return. The welded flanges reduce the connection
cross-section of the boiler to the calculated pipe diameter
( Tab. 40 and Tab. 41).
Provide an additional gasket to seal the flange
connection.

20
hydraulically shut off multi boiler systems, and to provide
188
constant control of heating water flow rates (system
158 examples Fig. 36, page 46 and Fig. 38, page 50).
170 They are particularly suitable for special functions in
systems with Ecostream cast iron boilers.
