Producdt Description:
The ZCZHQ-II Overall 304 Flame Arrester is a premium, high-safety flame arrester solution designed for the most demanding industrial environments. While standard models often limit stainless steel to internal components, the ZCZHQ-II series is engineered with a full 304 stainless steel construction, including the housing, flanges, and the high-precision flame element. This all-stainless design provides unmatched resistance to atmospheric corrosion and aggressive chemical vapors, making it the gold standard for pharmaceutical, food-grade, and coastal chemical processing facilities.
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.

Selecting the Right Stainless Steel Arrester for Your Facility
Q1: What does “Overall 304” mean for this flame arrester?
A1: It means that every major structural component, including the outer housing, the internal flame element, and the connecting flanges, is made from high-grade 304 stainless steel.
Q2: Is this model suitable for corrosive chemical environments?
A2: Yes. The 304 stainless steel construction is specifically designed to resist oxidation and corrosion from many industrial chemicals and saline coastal air.
Q3: Can the flame element be removed for cleaning?
A3: Absolutely. The ZCZHQ-II design allows for straightforward disassembly, enabling the flame element to be inspected and cleaned to ensure continued flow efficiency and safety.
Q4: Which gas groups is the ZCZHQ-II compatible with?
A4: Our standard units are designed for Group IIA and IIB3 gases. However, custom gap sizes can be engineered for more volatile Group IIC gases like hydrogen.
Q5: What flange standards are supported?
A5: We manufacture to all major global standards, including ANSI, DIN, JIS, and GB, ensuring seamless integration into your existing piping system.
