The ZCZHQ-II Explosion-Proof Type Flame Arrester is a premier safety solution engineered to prevent the propagation of fire through industrial piping systems. Designed as a robust “firewall” for your infrastructure, this device utilizes high-precision flame elements to quench flames instantly by absorbing thermal energy. Whether integrated into vapor recovery systems or storage tank vents, the ZCZHQ-II provides reliable, bi-directional protection against deflagration events.
Producdt Description:
The core safety function of the ZCZHQ-II is delivered by its internal flame elements, which quench flames by rapidly absorbing and dissipating thermal energy. We offer two primary types of internal filtration technology to meet your specific operational safety standards:
Corrugated Filter Element: This high-efficiency flame element is supported by a matrix of stainless steel, copper-nickel alloy, aluminium, or aluminium alloy. It is specifically engineered to prevent the fierce flames of deflagration and can withstand intense mechanical and thermal effects. Its unique corrugated structure ensures that flow resistance is small, while the component remains easy to clean and replace during routine maintenance.
Metal Mesh Filter Element: This specialized flame element is composed of overlapping layers of stainless steel or copper mesh with wire diameters ranging from 0.23 mm to 0.315 mm. Following standard safety protocols in China, these elements usually utilize 16–22 mesh metal screens arranged in 4–12 layers to provide a dense, fire-quenching path for hazardous vapors.

Q1: How does the ZCZHQ-II “quench” a flame?
A1: The internal flame element acts as a heat sink. As the flame attempts to pass through the narrow channels of the corrugated matrix, the thermal energy is rapidly absorbed by the metal, cooling the gas below its ignition point and extinguishing the fire.
Q2: Can the ZCZHQ-II be installed in any orientation?
A2: Yes. The ZCZHQ-II is a bi-directional flame arrester, meaning it can stop flames from either direction, providing flexibility for horizontal or vertical piping runs.
Q3: What is the difference between this and a detonation arrester?
A3: The ZCZHQ-II is an explosion-proof type optimized for deflagrations (subsonic flames). For high-speed supersonic shockwaves, a dedicated detonation flame arrester like the ZCGZJII-H is required.
Q4: Is the flame element replaceable?
A4: Absolutely. We provide standalone flame elements that can be easily swapped into the ZCZHQ-II housing, making maintenance cost-effective and straightforward.
Q5: Which material is best for chemical processing plants?
A5: For facilities handling aggressive chemical vapors, we highly recommend the Overall 304 or 316L Stainless Steel configuration for its superior corrosion resistance and longevity.
