Fire Fighting Equipment

Fire Fighting Equipment Manufacturer & OEM Supplier

We manufacture ductile iron fire hydrants, municipal water nozzles, and pressure-tested rubber-lined fire hoses for municipal networks, industrial facilities, and high-rise standpipe systems. All assemblies are engineered to withstand continuous operating pressures up to 1.6 MPa (232 PSI) and undergo 100% hydrostatic shell and seat testing prior to shipment.

Manufacturing Standards & Quality Assurance

Hydrostatic Pressure Testing (100% Test): Every hydrant body undergoes shell testing at 2.4 MPa (1.5 times working pressure) for 60 seconds with zero structural deformation. Seat sealing tests are performed at 1.6 MPa with zero leakage.

Protective Coating: Exterior and interior iron surfaces are coated with Electrostatic Fusion Bonded Epoxy (FBE) with a minimum dry film thickness of 250 um. Coating adhesion is verified via cross-cut testing (ISO 2409) and salt spray exposure tests.

Hose Proof & Burst Testing: Hose samples undergo proof pressure tests at 2 times working pressure and destructive burst testing per ISO 1402 / EN 14540 criteria.

Thread & Flange Inspection: All inlet flanges and outlet threads are verified using GO/NO-GO thread plug and ring gauges to ensure secure engagement with local fire brigade adapters.

FAQ

Q: What flange connection standards do your outdoor fire hydrants support?

A: Our hydrants are routinely manufactured with flanges conforming to EN 1092-2 PN10/PN16, ANSI B16.1 Class 125/150, and BS 4504. Special bolt hole configurations or raised-face designs can be machined from customer-approved CAD drawings.

Q: How do your above-ground hydrants prevent freezing in sub-zero climates?

A: Our dry-barrel outdoor hydrants feature an automatic drain valve located at the base. When the main valve stem is fully closed, the drain port opens automatically, allowing residual water in the upper barrel to drain into the surrounding gravel bed to prevent freeze cracking.

Q: What materials are used for the main valve stem and seat to prevent corrosion?

A: Valve stems are fabricated from solid stainless steel (SS304 or SS316), and valve seats are cast from high-strength brass/bronze alloys (HPb59-1 / C36000), preventing galvanic corrosion and binding after prolonged periods of inactivity.

Q: Can you supply fire hoses pre-fitted with specific national coupling standards?

A: Yes. Fire hoses and branch pipes can be pre-rigged with tied-in aluminum or brass couplings, including Storz, BS336 Instantaneous, NH/NST, or Camlock fittings according to project specs.

Q: What is the factory minimum order quantity (MOQ) and standard lead time?

A: Standard MOQ is 50 pieces for fire hydrants and 1,000 meters for rubber-lined fire hoses. Regular production lead time ranges from 25 to 35 days following order confirmation and drawing sign-off.

Q: What test documentation accompanies each export consignment?

A: Each shipment includes a Factory Acceptance Test (FAT) dossier containing hydrostatic test certificates, material heat analysis reports (EN 10204 3.1), and coating thickness logs.
