Pipeline gas water and oil removal filter cartridge long-distance pipeline filtration natural gas particle filter element
During the transportation process of natural gas long-distance pipelines, it is inevitable to carry solid particles (pipeline corrosion products, welding slag, dust, etc.) and liquid impurities (free water, condensate oil, etc.), which will increase pipeline resistance, cause pipeline erosion, damage ancillary equipment, valves and instruments, wear compressor blades, and shorten the service life of pipelines and devices. The filter element, as the core component of the filter, directly determines the performance of the natural gas station filter.
Product Introduction
The technical advantage of FO series filter cartridges comes from their precise material combination and structural design:
1. Graded fiberglass media - deep filtration without channels
The filter element is made of resin impregnated glass fiber medium, arranged layer by layer according to the fiber diameter. This structure ensures that the collected particles are evenly distributed throughout the filter body, avoiding early failure caused by surface blockage of traditional filters and achieving efficient deep filtration without channels.
2. Positive medium migration barrier - eliminating secondary pollution
The filter element is equipped with a cellulose barrier layer impregnated with resin, effectively preventing the migration of glass fibers to downstream media. This design is particularly important for protecting precision equipment such as downstream compressor dry gas seals and measuring instruments.
3. High strength central tube - anti crushing guarantee
The heavy-duty aluminum plated steel center pipe is not only corrosion-resistant, but also provides a compressive strength of 100 psi. Laboratory tests have shown that the average compressive strength of FO-472G exceeds 100 psid, while a mainstream competitor only has 34 psid.
4. Resin coated fiberglass mesh - maintains its shape and is easy to maintain
The glass fiber mesh coated with outer resin maintains its shape and density throughout the entire life cycle of the filter element, resisting handling damage while reducing the accumulation of external dirt.
In recent years, with the acceleration of the localization process of natural gas pipeline station filter cartridges, the domestic filtration equipment industry has established a complete research and development, manufacturing, and testing system. According to industry research, more than 90% of the filter cartridges in natural gas long-distance pipeline stations were once imported products, and domestic substitution can shorten the procurement cycle by more than 50% and save procurement costs by more than 50%.
Industry practice has shown that the comprehensive performance of newly developed domestically produced filter cartridges can reach the technical level of similar imported products, and some key indicators even exceed those of imported products. By combining multiple layers of filter materials and researching new filter cartridge structures, and continuously optimizing and adjusting them based on test results, a domestically produced filter cartridge that meets the practical requirements for on-site use of natural gas long-distance pipelines can ultimately be developed.
