Explosion proof corrugated flame arresting for storage tank

Description

Explosion proof corrugated flame arresting for storage tank prevents the external flame from entering the equipment containing flammable and explosive gases or prevents the flame from spreading between the equipment room. Explosion proof corrugated flame arresting for storage tank is designed and manufactured based on the principle that the flame passes through the narrow hole of the heat conductor and is extinguished due to heat loss. The fire barrier layer structure of Explosion proof corrugated flame arresting for storage tank has a gravel type, a wire mesh type or a corrugated type.

Explosion proof corrugated flame arresting for storage tank is one of the types of flame arresting used to prevent the flame from spreading from flammable gases and liquids and preventing tempering and causing an explosion. The fire-retardant layer in such a flame arresting is usually pressed by a stainless steel strip or a copper-nickel alloy material, and the size of the strip is determined by the nature of the gas and the flame speed. Regarding the working principle of the flame arresting, there are currently two main viewpoints: one is based on heat transfer; the other is based on the wall effect. Explosion proof corrugated flame arresting for storage tank is mainly composed of a casing and a fire-resistant plate. The casing should have sufficient strength to withstand the impact pressure generated by the explosion. Explosion proof corrugated flame arresting for storage tank can block the violent flame of detonation and can withstand the corresponding mechanical and thermal effects, with low flow resistance and easy to clean and replace. The ribbed flame retardant plate is supported by stainless steel, copper-nickel alloy, aluminum or aluminum alloy.

Characteristics

The structure is reasonable, light weight, corrosion resistant, easy to repair and easy to install. The flame arresting core is made of stainless steel, which is corrosion resistant and easy to clean. The anti-explosion performance is qualified, and the 13 consecutive detonation performance tests can prevent fire at each time; the anti-firing performance is qualified, and the anti-firing test has no tempering phenomenon for 1 hour; the shell water pressure test is qualified.

Installation and Maintenance

In order to ensure the fire retarding effect of explosion proof corrugated flame arresting for storage tank, it should be checked every six months. Check the fire barrier for defects such as blockage, deformation or corrosion. The blocked fire-retardant layer should be cleaned to ensure that each hole is unobstructed, and the fire-resistant layer that is deformed or corroded should be replaced. When cleaning explosion proof corrugated flame arresting for storage tank core parts, it should be purged with high pressure steam, non-corrosive solvent or compressed air, and should not be brushed with sharp hardware. In order to facilitate on-site installation, our company has adjusted the fire-resistant core parts, which is not affected by the direction of the gas. The site can be directly installed on the required pipeline according to the flange standard. explosion proof corrugated flame arresting for storage tank is generally installed at a distance burning. The position of the furnace is about 5-10m, which can be installed horizontally or vertically; the pipeline installed by explosion proof corrugated flame arresting for storage tank must be clean, and there should be no impurities, dirt and other things blocking the gap of the fire-resistant core member, affecting the normal use of the flame arresting.

The fire-proof performance of explosion proof corrugated flame arresting for storage tank is regularly tested by 13 consecutive subsonic flame tests, which meets the requirements of national standards: explosion proof corrugated flame arresting for storage tank is protected from wear and tear on the flange sealing surface before leaving the factory, and the plastic protective cover for the import and export is supported. Be sure to remove the blue flange cover before installation on site:

When re-installing explosion proof corrugated flame arresting for storage tank, the gasket should be renewed and the sealing surface should be clean and free from damage and must not leak.
