Producdt Description:
The ZCZGB-II Drawer Flame Arrester is an advanced explosion-proof safety solution designed for critical process piping where operational uptime is a priority. The hallmark of this Flame Arrester is its innovative, service-friendly modular housing. By drastically reducing the time required to inspect and clean the internal quenching matrix, the ZCZGB-II significantly lowers operational downtime and labor costs compared to standard in-line arresters.
Rapid-Access Flame Elements & Thermal Quenching
The core of the ZCZGB-II’s performance lies in its unique drawer-type configuration, which provides immediate access to the internal safety components.
-
Slide-Out Flame Elements: This unit is equipped with high-precision flame elements, available in corrugated ribbon or multilayer mesh designs. These flame elements can be accessed in seconds via the integrated drawer mechanism, allowing for rapid maintenance without dismantling the pipeline.
-
High-Surface-Area Thermal Sink: The internal matrix of the flame elements utilizes advanced thermal energy absorption. This technology cools combustion gases below their ignition point instantly, extinguishing subsonic flame fronts with maximum reliability.
Key Technical Performance & Features
-
Bi-Directional Quenching: Engineered to stop flame fronts originating from either side of the pipe, this Flame Arrester offers versatile and total protection for complex industrial piping layouts.
-
Industrial Grade Materials: To ensure long-term durability, the ZCZGB-II is manufactured in heavy-duty Carbon Steel or premium 304/316L Stainless Steel. These materials are built to withstand high temperatures and aggressive chemical vapors found in hazardous environments.
-
Optimized Flow Dynamics: The internal drawer configuration is precision-engineered to maintain high flow rates. This design ensures a minimal pressure drop, guaranteeing that your system’s operational efficiency is never compromised.
-
Global Standard Compatibility: The ZCZGB-II is fully compatible with ANSI, DIN, JIS, and GB flange specifications, allowing for easy and seamless worldwide integration.
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.

The Engineering Secrets Behind our Bi-Directional Drawer Quenching
Q1: What makes the “Drawer” design better than standard arresters?
A1: The drawer design allows for the flame elements to be removed and inspected without removing the arrester housing from the pipeline, reducing maintenance time from hours to minutes.
Q2: Can the ZCZGB-II handle deflagrations in both directions?
A2: Yes. The ZCZGB-II is a bi-directional flame arrester, providing a reliable fire barrier regardless of the direction of the flame front.
Q3: Is this model suitable for vapor recovery units (VRU)?
A3: Absolutely. Its combination of high-efficiency quenching and easy-access maintenance makes it an ideal safety device for the oily vapors often found in vapor recovery units.
Q4: How do I clean the drawer-type flame elements?
A4: Simply slide out the drawer, remove the flame elements, and use low-pressure steam or a non-corrosive solvent to clear the matrix. Avoid abrasive tools that could damage the precision gaps.
Q5: What materials are available for corrosive environments?
A5: We offer the ZCZGB-II in SS316L Stainless Steel for the housing, drawer, and elements, providing maximum resistance to chemical corrosion and extreme weather.
