Deep in the mine, flames in the pipeline are "racing forward." The copper mesh core stands silently, using its high-temperature resistance to block the danger. This is the power of the mine flame arrestor. It is not just a "lump of iron"; inside, there is a copper mesh core. The FHQ flame arrestor reflects our hope and responsibility for the future.

The mobile mine flame arrestor is of the FHQ type. It is a device used in coal mine gas pipelines to prevent flashback during combustion and is widely applied. By utilizing the heat dissipation effect of the copper mesh, it blocks the propagation of flames. This flame arrestor, along with the explosion-proof device, is part of the safety facilities in the gas extraction and utilization system. The flame arrestor is suitable for installation in gas output pipeline systems, typically placed near users or gas pumps. It serves to protect the safety of the mine, extraction pump stations, and users.

FHQ-9: Suitable for pipe diameters of 600mm, length 1815mm, 6 layers of copper mesh, weight 620kg.

FHQ-DN300: Suitable for pipe diameters of 300mm, specification DN300, number of copper mesh layers not explicitly specified.

FHQ Series: Includes 13 specifications from FHQ-0 to FHQ-12, corresponding to pipe diameters from DN150 to DN1000, lengths from 1550-3000mm, and 3-6 layers of copper mesh.

Installation Steps:

1. Determine the installation location

It should be installed close to potential flashback points to shorten the path of flame propagation.

Avoid installing in areas prone to impact, vibration, or high-temperature exposure.

2. Confirm the installation direction

Install according to the arrow direction on the device housing to ensure alignment with the medium flow direction.

Incorrect direction may result in failure of flame arrestor function or even damage to the equipment.

Did you know? Installing the mine flame arrestor horizontally ensures even force distribution on the flame arrestor core, better sealing, and a longer service life. Use it horizontally for uncompromised safety!
