Explosion proof flame arrester for storage tanksTesting experiment

：Whether the performance of the flame arrester can achieve the expected effect and play a role in flame retardancy must be tested. In addition to possessing a certain degree of mechanical strength,

It also needs to undergo explosion resistance and burn resistance tests,And it should meet the requirements of the test standards.Explosion proof test: It refers to igniting the combustible gas in the test device within a certain distance, and the flame or spark generated cannot pass through the flame arrester and be prevented and extinguished.

Flame endurance test: It refers to the continuous combustion of a combustible gas flame through a flame retardant layer without reignition. The fire-resistant layer can withstand a certain amount of timeThe flame burns without being burned out.

Explosion proof flame arrester for storage tanksStructure Design

：The product consists of two parts: the core and the shell. The core is made up of two layers of ultra-thin stainless steel strips, one pressed into a wavy N shape and the other flat steel strip

It is tightly wrapped around the center of the circle.Thus, countless end faces are formed, forming small triangular straight channels, and there is a cross shaped support structure inside the core (or

The Y-shaped frame is pressed onto the surface to enhance the reliability of the core component and avoid the risk of core damageThe explosive pressure generated by the ignited medium disperses. The medium passes through a narrow triangular channel,

Flame arresters are also used to prevent the spread of flames in pipelines, based on the principle of "wall effect"It is the collision between the flame and the wall that converts energy, reducingTemperature. Based on this principle, the height of the triangular hole is designed to prevent the flame from passing through, and sufficient channel length is added to absorb the heat of the flame,

1Extinguish it in the core component,

Avoiding the possibility of gas reigniting at the other end of the core component.

Design and Manufacturing Performance

：

The material requirements for the shell itself are relatively strict, generally using media such as aluminum alloy, stainless steel, cast iron, etc., and the size must be executed according to the prescribed standards;

2. During the manufacturing process, the castings used for the shell must not have problems such as damage, cracks, sand holes, etc., as such castings may affect the effectiveness of use;3. During the manufacturing process of the shell, a water pressure test should be conducted according to regulations, and it can only be used after passing the test;4. The flame arrester with corrugated structure will be processed and made with steel strips according to regulations. Such steel strips should be bright and free of oil stains, rust spots, and other stains;5. The pore size on the fire-resistant layer should be completely consistent and evenly distributed, so it should be kept unobstructed;

6. The fire-resistant layer installed inside the shell cannot shake, so its contact surface needs to be tightly connected. After assembly, we also need to conduct a fire-resistant test according to regulations.

Manufacturer's after-sales service

：Our factory can provide separate corrugated flame retardant core components according to user requirements while producing flame retardant breathing valves and corrugated flame arresters

1. During maintenance, it was found that the fire-resistant core components were corroded due to their age, and replacement was required.2. During the cleaning process, it was accidentally damaged and cannot be rewound.Our factory can remanufacture and supply flame arresters or corrugated flame arresters produced by our factory based on the model and specifications provided by the user; If it is not produced by our factory, it should be provided

The outer diameter size of the flame retardant core and the height of the flame retardant box are measured by our factory according to the scale
