FM200 Pipe Network Gas Cylinder

Complete System Introduction:

The HFC-227ea (FM200) automatic fire extinguishing system is a comprehensive gas-based fire suppression solution. The complete system comprises the following components:

• Fire extinguishing agent cylinder sets and mounting brackets

• Drive gas cylinder sets and container valves

• Liquid check valves and gas check valves

• Drive devices and gas control piping

• Manifolds, selection valves, tees, reducing tees, elbows, and reducing elbows

• Flanges, safety valves, and signal feedback devices

• Pipe networks and discharge nozzles

• Fire detectors and gas fire extinguishing control panels

• Audible and visual alarms, alarm bells, discharge indicators, and emergency start/stop buttons

Fire Extinguishing Agent Cylinder Set

1) Purpose

The cylinder set is designed to store HFC-227ea (FM200) fire extinguishing agent. It provides multiple essential functions including agent sealing, controlled release, refilling, overpressure relief, and pressure indication.

2) Structure

The cylinder set consists of a container valve, a siphon tube, and a storage container.

• Storage Container: A refillable, welded steel cylinder finished with red epoxy coating for corrosion resistance.

• Container Valve: Comprises a valve body, actuating device, piston, pressure indicator, and pressure relief device. Once assembled with the siphon tube, the container valve is installed on the cylinder opening. It can be activated either pneumatically (via nitrogen pilot pressure) or manually to release the extinguishing agent.

3) Main Technical Parameters

4) Installation Instructions

1. Positioning: The installation location must comply with the design drawings. Cylinders should be arranged in the specified order by their identification numbers. The height difference between cylinders should not exceed 20 mm. A minimum clearance of 1.0 m should be maintained between the operating side and any wall or between adjacent operating sides.

2. Manual Emergency Operation: In an emergency, remove the safety pin from the actuator, engage the manual handle one by one, and rotate the cam lever to open all container valves and release the extinguishing agent.

5) Maintenance Instructions

Perform a visual inspection on a monthly basis. The cylinder set may continue to be used only if the following conditions are confirmed:

• No impact deformation or mechanical damage

• No visible surface rust or corrosion

• Protective coating remains intact

• Safety pin and tamper seal are in place and undamaged

6) Important Note

The safety pin on the container valve is specifically designed to lock the cam lever in position. The safety pin must be removed only when manual actuation of the container valve is required. Locking the cam lever does not interfere with normal nitrogen‑pneumatic actuation of the container valve during automatic system operation.
