I. Product Introduction

The ADGZDI flame arrester is a safety device installed at the end of pipelines for conveying and discharging combustible gases, designed to prevent flames from spreading into the pipeline due to backfire. It is primarily composed of a flame arrester element, housing, gaskets, and connecting parts.

The ADGZDI pipe-end flame arrester is cast, featuring a compact structure and easy disassembly.

II. Working Principle

The core of the ADGZDI flame arrester is the corrugated flame arrester plate, made of a type of stainless steel material that allows gases to pass through, featuring numerous tiny channels or gaps. The requirement is for the gaps or channels in the corrugated flame arrester plate to be as small as possible. Consequently, upon the entry of flames into the arrester, the flame-retarding elements divide the flames into numerous small flame streams. Due to the heat transfer effect (gas cooling) and the wall effect, the flame streams are extinguished.

Section 3: Gas Type and Flame Retardant Gap Refer to Data Sheet

Section 4: Product Advantages

1. Provide professional fire arrester calculations and CAD drawings based on the data sheet provided by the customer and the operating conditions.

2. Eddie has obtained the IIA Fire Extinguisher certification and the patent certificate.

3. The flame arrester components are made of stainless steel corrugated flame arrester plates, featuring compact structure, high flow capacity, low pressure drop, and high reliability.

4. Carbon steel valve bodies are internally and externally coated with anti-rust primer, with an epoxy topcoat applied; stainless steel valve bodies are sandblasted.

5. Packaging is uniformly done in standard wooden crates.
