Gas filter element

The gas filter element is a necessary separation and purification equipment element for gas gathering stations, compressor stations, offload stations, pigging stations, terminal stations, and various application fields on natural gas gathering and transmission pipelines and gas transmission pipelines. It can effectively filter the dirt in the pipeline and the debris from the pipe wall, so as to ensure the safe operation of gas transmission and gas equipment, and meet the pipeline transmission and users' requirements for gas quality.
Filter medium
Gas-liquid and liquid-solid separation of nitrogen, carbon dioxide, propane, butane, etc.

Equipment performance
1. Large filter area; High precision, large filtering area, large flow, small equipment diameter, and small footprint.
2. Internal thread structure for enhanced compression resistance:
Wide chemical compatibility, large flux, low differential pressure, Can be washed and regenerated, economical.
3. Material:
Material: multi-layer sintering
4. Structure:
Sparse outside and dense inside, honeycomb structure, large dirt holding capacity.

Equipment advantages

During the transportation of gas pipelines, gas source impurities and pipeline mechanical impurities will affect the gas transmission quality and damage some metering and pressure regulating equipment on the pipeline.
Therefore, gas filtering equipment shall be installed in front of each receiving and dispatching station or important equipment to ensure the safety of downstream equipment (sometimes it may go through multi-stage filtering).
The filter element is also the main component of this filter equipment, so the selection of the filter element directly affects the filtering effect.
According to the unique properties of gas, stainless steel metal mesh is selected as the main filter material, and the filter area of the filter element is increased through the wave-breaking structure, so as to ensure the good circulation of gas and increase the amount of pollutants.
High and low-temperature resistant asbestos gasket is used as a sealing material to ensure good sealing of some low-temperature gases, such as compressed liquefied petroleum gas.
The filter element shall be cleaned or replaced in time according to the change of differential pressure during use.
