Replace Velcon FO series natural gas particle filter cartridge FO-638PLF gas pipeline solid impurity filter element
The core pain points in the operation and maintenance of natural gas valve stations, long-distance pipelines, compressor stations, and CNG mother stations have never been simple filtration, but stable gas-liquid separation, long-term operation with low pressure difference, and universal spare parts that do not affect the project schedule.Imported Velcon I-6 series coalescing filter cartridges are standard in the industry, with stable performance but long supply cycles, high premiums for original spare parts, and uncontrollable procurement cycles.Our full range of Velcon replacement natural gas coalescing filters, 1:1 benchmarking of original factory size, accuracy, structure, and adaptability to working conditions, perfectly replace imports, offer full cost-effectiveness, and are compatible with mainstream equipment throughout the station, without the need for machine modification or direct replacement!
Product Introduction
Core material | Industrial grade durable, suitable for harsh gas conditions
Adopting multi-layer imported fiberglass composite filter materials and gradient filtration structure, it balances large pollutant absorption capacity and high-precision agglomeration effect, which is different from ordinary single-layer filter materials:
1. Accurately intercept natural gas dust and solid impurities, efficiently aggregate small oil and water mist, and prevent pipeline accumulation, equipment corrosion, and pressure regulating valve jamming problems
2. High strength epoxy resin adhesive curing, stable and non loose pleats, no fiber shedding, no deformation or failure under high-pressure airflow impact
3. Carbon steel anti-corrosion skeleton+thickened sealed end cap, matched with NBR nitrile rubber sealing ring, resistant to oil and gas corrosion, high and low pressure pulsation, suitable for long-term continuous industrial operation
4. Standard flow direction for external in and internal out, fully matching Velcon's original filtering logic, with filtering efficiency and pressure drop curve consistent with the original factory
The Application Value of Domestic Replacement Filter Cartridge
1. Economic advantage: The price of domestically produced replacement filter cartridges is generally 30% -50% of that of imported brands. The procurement cycle is significantly shortened, which can effectively reduce inventory pressure and avoid the situation of passive replacement of filter cartridges due to expiration.
2. Technical reliability: On the premise of strictly following industry standards, domestically produced substitute filter cartridges have reached international advanced levels in core indicators such as filtration efficiency, compressive strength, and dust holding capacity.
3. Supply chain security: Domestic substitution effectively reduces the dependence of key consumables on a single imported source and enhances the independent and controllable ability of natural gas station operation and maintenance.
Adaptation scenario
Natural gas valve station, long-distance pipeline compressor station, urban gas pressure regulating station, CNG/LNG refueling station, petrochemical gas transmission system, industrial gas pre filtration system
It can be used as a complete set of separation filter cartridges to achieve a complete process of filtration, aggregation, and separation, thoroughly purifying the gas medium, protecting core equipment such as flow meters, pressure regulating valves, and compressors, and extending the service life of the entire machine.
