阻爆轰型管道阻火器Selection:

1Oil and gas emissions from loading and unloading facilities(Or recycling)Explosion proof flame arresters should be installed between the gas phase pipelines of the main pipeline and each branch pipeline

2Before connecting the combustible gas venting pipeline to the torch, if a flame arrester is installed, a detonation resistant flame arrester should be selected.

3The selection of materials for flame arresters should meet the following requirements:The flame arrester housing installed at the pipe end should be made of cast iron and have a magnesium content not exceeding0 5 %The cast aluminum alloy can also be made of other materials according to design requirements:

The flame arrester shell installed in the pipeline should be welded with cast steel or carbon steel, or other materials can be used according to design requirements;The core components of the flame retardant layer and the flame arrester core shell and core pressure ring installed in the pipeline should be made of non flame retardant materials

ruststeel;The flame arrester core shell and core pressing ring installed at the pipe end should be made of cast iron or cast aluminum.

阻爆轰型管道阻火器Testing requirements: Whether the performance of the flame arrester can achieve the expected effect and play a role in flame retardancy, the flame arrester must be tested. Flame arresters have a certain mechanical strength

In addition, it also needs to undergo explosion resistance and burn resistance tests, and meet the requirements of the test standards. Explosion proof test refers to igniting the combustible gas in the test device within a certain distance, and the flame or spark generated cannot penetrate

The test of being prevented and extinguished by passing through a flame arrester is called a flame retardant test. The flame resistance test is a test in which a combustible gas flame passes through a flame retardant layer and continues to burn on top of the flame retardant layer without reignition. Fireproof layer energy

The test that can withstand a certain period of flame combustion without being burned out is called the burn resistance test. According to the purpose of use, flame arresters can have both explosion resistance and burn resistance, or they can only have explosion resistance

Capable or heat-resistant performance. Therefore, the explosion resistance and fire resistance of flame arresters are the main items for testing and identifying flame arresters. Flame arresters that have not undergone such testing and identification cannot be used.

阻爆轰型管道阻火器Principles of repair and maintenance:

1)The flow direction mark on the flame arrester must be consistent with the flow direction of the medium.

2)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 whether the label is consistent with the requirements of the installed pipeline.

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.

5)When 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 fire-resistant layer, the gasket should be updated and the sealing surface should be confirmed to be clean and undamaged, without any air leakage.
