Producdt Description:
In Line Flame Arrester is mainly composed of shell and fire element. There are two kinds of commonly used metal mesh filter element and corrugated filter element. The metal mesh filter element is composed of stainless steel or copper mesh with a diameter of 0.23-0.315 mm and overlapping layers. In Line Flame Arrester in China usually use 16-22 mesh metal mesh with 4-12 layers.
The corrugated filter element is supported by stainless steel, copper-nickel alloy, aluminium or aluminium alloy. Corrugated flame retardant can prevent the fierce flame of deflagration, and can withstand the corresponding mechanical and thermal effects, flow resistance is small, easy to clean and replace.
Installation:
- Remove all flange cover and discard all packaging materials.
- Check the seat, the matching flange gasket on the seat surface. It must be clean, flat, scratch-free, corrosion-resistant, tool traces.
- Check the gasket to ensure that the material is suitable forapplication.
- Lubricate all studs and nuts with proper thread lubricant. If the fastener is a high temperature stainless steel material, a back-grabbing compound, such as molybdenum disulfide, is used.
- Inside gasket of bolt ring.
- Installing flange of Inline flame arrester shell to butt with flange of pipeline, attention should be paid to the position of lifting handle and top nut of In line flame arrester element to facilitate the removal of In line flame arrester elements in the future.

Technical Performance FAQ
Q1: What is the maximum distance for installing a deflagration flame arrester?
A1: Deflagration arresters must be installed within a specific distance from the ignition source, as defined by their certification, to prevent the flame from accelerating into a detonation.
Q2: Can the ZCZHQ-II be used for hydrogen (Group IIC) applications?
A2: Yes. While standard units cover Groups IIA and IIB3, we can customize the flame element gap (MESG) specifically for more volatile Group IIC gases like hydrogen.
Style 2: Maintenance & Installation FAQ
Q3: How often should the internal flame element be cleaned?
A3: Maintenance frequency depends on your media; however, the ZCZHQ-II is designed for easy disassembly, allowing the flame element to be inspected and cleaned regularly to maintain flow efficiency.
Q4: Is the ZCZHQ-II rated for bidirectional flow?
A4: Absolutely. Our ZCZHQ-II series is engineered for bidirectional protection, meaning it will quench a flame front originating from either direction within the pipe.
Q5: What is the benefit of choosing “Overall 304” stainless steel?
A5: Choosing a full 304 or 316L stainless steel construction ensures that the housing and flanges resist atmospheric and chemical corrosion, significantly extending the service life of the flame arrester.
