FAQ
Q: What is the difference between French type and other hydrants?
Compared to British or American hydrants:
French hydrants typically use symmetrical instantaneous couplings (Guillemin type).
Outlet sizes commonly DN65 or DN100.
Operating nut shape and dimensions differ from United States or United Kingdom hydrants.
Designed mainly according to EN standards instead of AWWA standards.
Q: What materials are commonly used?
Body: Ductile iron (GGG50)
Stem: Stainless steel
Valve sealing: EPDM
Coating: Fusion bonded epoxy (FBE), usually ≥250μm
Q: What pressure ratings are available?
Common nominal pressures:
PN10
PN16
PN25 (upon request)
Working pressure depends on project requirements and certification.
Q: How does the anti-freezing system work?
French fire hydrants usually adopt a dry barrel design:
When closed, the water drains automatically from the upper chamber.
Only the underground pipeline remains pressurized.
Prevents freezing in cold climates.
