The ZCZHQ-II Detonation Flame Arrester is a heavy-duty safety component engineered to quench high-velocity flame fronts in industrial piping systems. Unlike standard models, the ZCZHQ-II is specifically designed to withstand the extreme pressures and supersonic shockwaves associated with detonations. This bi-directional flame arrester provides an impenetrable barrier, protecting critical infrastructure like tank farms and vapor recovery units from catastrophic fire propagation.
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.

Q1: What is the difference between the ZCZHQ-II and a deflagration arrester?
A1: The ZCZHQ-II is rated for detonations, which means it can stop supersonic flames and intense shockwaves, whereas standard arresters are only designed for slower-moving deflagrations.
Q2: Can I install this detonation flame arrester at any distance from the ignition source?
A2: Yes. Because it is rated for detonations, the ZCZHQ-II can be placed in long piping runs where flames have the distance to accelerate to high speeds.
Q3: Is the internal flame element replaceable?
A3: Absolutely. The ZCZHQ-II is designed for easy disassembly, allowing the flame element to be inspected, cleaned, or replaced to ensure maximum safety.
Q4: Which gas groups is this model compatible with?
A4: Our standard units cover Groups IIA and IIB3. We also provide specialized configurations for Group IIC (Hydrogen) applications requiring strict MESG compliance.
Q5: What materials are available for the ZCZHQ-II housing?
A5: We offer Carbon Steel for standard oil/gas use and 304 or 316L Stainless Steel for corrosive chemical processing and coastal environments.
