The gas filter element is suitable for the gas-liquid and liquid-solid separation of natural gas, artificial gas and other non-corrosive gases, such as nitrogen, propane, carbon dioxide, butane, etc. It is an essential separation and purification equipment component for natural gas collection and transmission pipelines and gas collection stations, compressor stations, distribution stations, pipe cleaning stations, terminal stations and various application fields.

The gas filter element can effectively filter the dirt in the pipeline and the debris that flakes off the pipe wall to ensure the safe operation of gas transmission and gas equipment, and meet the pipeline transportation and user requirements for natural gas quality.

During the transportation process of gas pipelines, gas source impurities and pipeline mechanical impurities will affect the quality of the gas transmission and damage some metering and pressure regulating equipment on the pipeline. Therefore, gas filtration equipment must be installed before each receiving station or important equipment to ensure the safety of downstream equipment (sometimes it may have to go through multi-stage filtration).The filter element is also the main element of these filtration equipment. Therefore, the selection of the filter element directly affects the filtration effect. According to the unique properties of the gas, stainless steel metal mesh is selected as the main filter material, and the filter area of the filter element is increased through the folding wave structure to ensure good circulation when the gas passes through, while increasing the amount of dirt.The sealing adopts high-temperature-resistant and low-temperature asbestos pads as the sealing material to ensure the good sealing of some low-temperature gases: such as compressed liquefied petroleum gas and other gases.The filter element should be cleaned or replaced in time according to changes in the pressure difference during use.

The service life of the filter element is greatly affected by the cleanliness of the filter medium, and the maintenance of the filter element is also very important.When the pressure difference at both ends of the filter exceeds a certain value, the filter element needs to be cleaned or replaced.When cleaning up, it should be carried out in a clean environment to prevent secondary pollution.High-pressure blowback can be used to clean up, or water can be used to backwash, but the filter element should be dried in time to prevent the support frame from rusting.Before installing the filter element again, be sure to check the position and wear of the sealing ring. If there is any problem, it needs to be replaced in time.
