ST‑636FD Large‑Flow Separator Cartridge For Natural‑Gas Pipeline

Within large‑scale natural‑gas filter‑separation systems, our Coalescer Filter matched ST‑636FD separator cartridge works as key secondary barrier cooperating with Oil Filtration Machine skids. Many field‑cases reveal small‑size ordinary separator filter cannot sustain huge gas‑throughput; after passing coalescer cartridge, residual micro‑droplets get re‑entrained by high‑speed gas‑stream and cause compressor‑rust and instrument‑malfunction. LEFILTER ST‑636FD wide‑channel separator filter cartridge is mass‑production catalog‑standard separator filter element. Thermal‑bonded PTFE‑coated 316‑stainless‑steel mesh makes this separator cartridge filter perfectly pair JMG‑series large‑flow coalescer filter cartridge. This gas‑phase‑special separator filter differs from aviation‑fuel CM‑series liquid‑medium‑use elements. Browse all gas‑phase‑filtering parts via gas filter element.

Mechanism of ST‑636FD Separator Cartridge

Post‑coalescence gas with tiny residual droplets flows into ST‑636FD separator filter cartridge after JMG‑series coalescer filter cartridge processing. Wide‑channel thermal‑bonded PTFE hydrophobic layer of separator filter element fully repels water‑and‑hydrocarbon droplets, only dry‑purified gas can penetrate mesh‑gaps. Trapped liquid accumulates on outer‑surface of this separator cartridge filter and slides downwards relying on gravity, completely solving liquid‑re‑entrainment defect of narrow‑mesh‑type ordinary separator filter. Even under pipeline full‑load maximum‑throughput condition, outlet‑gas residual‑liquid can be controlled below 8 ppm and satisfy natural‑gas transmission‑quality‑specification of gas filter system.

Performance‑Data Sheet

• Core‑Material：316 stainless‑steel + integral thermal‑bonded PTFE coating for separator filter element

• Liquid‑Blocking‑Efficiency of separator cartridge filter：≥99.95 %

• Max‑Working‑Pressure for natural gas filter：3.4 MPa

• Pressure‑Drop‑Advantage：40 % lower than small‑size separator cartridge

• Matching‑Coalescer：JMG‑full‑series coalescer cartridge filter

Each ST‑636FD separator cartridge has passed long‑duration high‑flow aging‑test before delivery, interchangeable for large‑PECO / Faudi filter‑separator housings and fits all Oil Filtration Machine land‑based & offshore gas‑facilities.

Large‑Pipeline‑Exclusive Advantages

1 Wide‑Mesh Low‑Pressure‑Drop Layout
Reduce power‑consumption of full‑load‑running gas filter cartridge system.

2 Non‑Peeling Thermal‑Bonded PTFE‑Coating
No‑coating‑shedding risk under multi‑year high‑speed‑gas scouring on separator filter element.

3 Perfect‑Matching for JMG‑Coalescer‑Series
Direct assembly without housing‑rebuild for coalescer cartridge filter.

4 Offshore‑Anti‑Corrosion‑Structure
Rust‑proof metal‑material adapts coastal‑offshore natural gas filter working‑platform.

Application Range

ST‑636FD separator cartridge acts as essential matching‑consumable for long‑distance natural‑gas trunk‑pipelines, large central compressor‑stations and offshore‑gas‑extraction‑platforms. It must be used together with coalescer filter cartridge for eliminating pipeline‑equipment liquid‑corrosion‑hazards.
