Stainless steel flame arrester

Stainless steel flame arrester model：GZW-B

Product Overview:stainless steelFlame arresterThis is a new type of combustible gas pipeline flame arrester, which belongs to the updated and upgraded new product. Shanghai Nanshipai Pipeline Flame ArresterUniversity of Science and Technology of China and Tianjin Fire Department of the Ministry of Public Security

Joint testing by the research institute shows that its performance fully meets the requirementsGB13347-92Petroleum and GasAccording to the regulations on the flame retardant performance and test methods of pipeline flame arresters. A flame arrester is a narrow hole that uses flames to pass through a thermal conductor

Gap time,Due to heatDesign and manufacture based on the principle of extinguishing after loss. The fire-resistant layer structure of flame arresters includes gravel type, wire mesh type, or corrugated type. Explosion proof stainless steel flame retardantWidely used in: chemical, petrochemical

Petroleum, papermaking, mining, electricity, liquefied gas, food and pharmaceutical, water supply and drainage, municipal, mechanical equipmentSupporting facilities, electronics industry, urban construction and other fields. Flame arresters can be used in conjunction with breathing valves,It can also be used separately

Use it. Installation in the road should generally follow theInstall horizontally or vertically according to the working conditions .

stainless steelFlame arresterworking principle： Flame arresterIt is composed of solid materials that can pass through many small, uniform, or non-uniform channels or pores of gasThe gap should be kept as small as possible,

Small enough to pass through flames. In this way, the flame enters the flame arrester and is divided into many small flame streams that are extinguishedExtinguish. The mechanism by which flames can be extinguished is through heat transfer and wall effect.

Heat transfer function: One of the necessary conditions for combustion is to reach a certain temperature,The ignition point. Below the ignition point,The combustion will stop. according toThis principle,As long as the temperature of the burning substance is lowered to its

Below the ignition point,It can prevent the spread of flames. When the flame passes through many fine flame arrestersAfter the passage, it will turn into several small flames. When designing the flame arrester components inside the storage tank flame arrester,Expand as much as possible

Contact between large and small flames and channel wallsarea,Enhance heat transfer,Reduce the flame temperature below the ignition point,Thereby preventing the spread of flames.Wall effect: Combustion is not a direct reaction between molecules,But it is influenced by external energy

ofexcite,Molecular bonds are disrupted,Generate activated molecules,Activated molecules split againFor short-lived but lively free radicals,Free radicals collide with other molecules,Generate new products,At the same time, it also generates new free radicals

continueCompared to other moleculesGenerate a reaction. When the combustible gas passes through the narrow passage of the flame retardant element,The collision probability between free radicals and channel walls increases,The free radicals involved in the reaction decrease.When the explosion-proof flame arrester is turned on

roadNarrow toTo a certain extent,The collision between free radicals and channel walls dominates,Due to a sharp decrease in the number of free radicals,The reaction cannot continueconduct,That is to say, the combustion reaction cannot continue to propagate through the flame arrester.

stainless steelFlame arresterPerformance：

1Qualified explosion resistance performance,continuous13The secondary explosion resistance performance test can block fire every time.

2Qualified fire resistance performance, fire resistance test1There is no tempering phenomenon within hours.

3The shell water pressure test is qualified. This product has a reasonable structure, light weight, and corrosion resistance. Easy to maintain and install. The flame arrester core is made of stainless steel material,Corrosion resistant and easy to clean.

Installation and Maintenance：

1、 To ensure the performance of the flame arrester meets its intended use, it is necessary to carefully read the instructions provided by the manufacturer before installing the flame arrester, and carefully check the label and the installed pipeline

Is the requirement consistent.

2、 The flow direction mark on the flame arrester must be consistent with the flow direction of the medium.

3、 It should be checked every six months. Check whether the fire-resistant layer has defects such as blockage, deformation, or corrosion.

4、 The blocked fire-resistant layer should be cleaned thoroughly to ensure that each hole is unobstructed, and any deformed or corroded fire-resistant layer should be replaced.

5When cleaning the flame arrester core components, high-pressure steam, non corrosive solvents, or compressed air should be used for blowing, and sharp hardware brushes should not be used.

6、 When reinstalling the flame retardant layer, the gasket should be updated and the sealing surface should be confirmed to be clean and undamaged, without any air leakage
