Fire Extinguisher
Product Overview
Industrial-grade portable and wheeled fire extinguishers engineered for commercial, marine, and heavy-industrial installations. Available in stored-pressure ABC dry chemical, carbon dioxide (CO2), and clean agent configurations to match specific class A, B, and C hazard profiles. Every cylinder undergoes hydrostatic pressure testing, with unique serial numbers laser-etched onto the cylinder base to guarantee 100 percent factory traceability and verifiable quality control logs, backed by complete mill test reports and regional compliance documentation available upon direct RFQ submission.
Working Principle, Materials & Construction
Cylinder Body
Deep-drawn alloy steel or seamless aluminum alloy. Minimum wall thickness maintained at 1.5 mm to 2.8 mm depending on cylinder volume and pressure rating.
Valve Assembly
Forged brass bodies equipped with safety release relief valves. Features nickel-plated brass stems and precision O-rings for leak-tight seal integrity.
Pressure Gauge
Bourdon tube type with color-coded operational zones, brass internal movement, and laser-welded sealing to prevent moisture ingress.
Discharge Mechanism
Reinforced rubber hose with internal steel wire braiding, coupled with a polypropylene or brass discharge nozzle calibrated for precise flow rates.

Operating temperature range: -30 degrees Celsius to +60 degrees Celsius (ABC Dry Powder); -20 degrees Celsius to +60 degrees Celsius (CO2).
Burst pressure threshold exceeds standard regulatory safety margins.
External finish: Electrostatic polyester-epoxy powder coating with a minimum dry film thickness of 70 micrometers, salt-spray tested to 500 hours.
Pull pin: Stainless steel with tamper-evident seal wire for visual inspection verification.
Discharge range: 4 to 9 meters depending on unit capacity.
Applications
Manufacturing Plants & Warehouses
ABC dry powder units positioned along egress corridors for Class A and B hazard mitigation.
Data Centers & Electrical Rooms
CO2 extinguishers deployed to prevent electrical short-circuit damage and eliminate post-discharge residue.
Marine & Offshore Rigs
Salt-spray resistant cylinders with marine-grade brackets and bronze valve assemblies.
Commercial Kitchens & Chemical Labs
Specialized wet chemical and clean agent configurations.

Manufacturing & Quality Control
Blanking & Deep Drawing
Automated hydraulic presses form seamless cylinder shells from certified coil stock, tracked via batch testing logs.
01
Welding
Robotic longitudinal and circumferential welding with ultrasonic and X-ray non-destructive testing (NDT) on pressure-bearing seams.
02
Surface Treatment
Multi-stage zinc phosphating immersion line followed by automated electrostatic powder spray application and thermal curing.
03
Pressure & Leak Testing
Pneumatic leak test under water bath immersion at 1.5 times working pressure prior to valve installation and final weighing.
04
Quality Management
Strictly operated under standardized quality management frameworks, with full material test reports and batch-specific inspection logs verified against laser-etched base serial numbers.
05
Customization & OEM
Private label silk-screen printing or aluminum nameplate embossing with distributor logos, operating instructions in target languages, and custom barcode/QR tracking integration.
Custom cylinder exterior color options meeting specific facility safety identification standards.
Flexible packaging options including reinforced export cartons, wooden pallets, and shrink-wrapped container loading configurations.
