5. Selection & Operation Guidelines

5.1 Filtration Efficiency & Precision

With 5 μm absolute filtration at ≥ 99.90% efficiency, the CS604LGT2DH13 effectively captures solid particles including:

· Pipe scale and rust fragments from pipeline internal surfaces

· Sand, dust, and formation fines from gas production

· Welding slag and debris from pipeline construction

· Iron sulfide particles and other corrosive by-products

This level of cleanliness protects compressors, turbines, valves, regulators, and metering equipment from abrasive wear and

 operational failure.

5.2 Replacement Indication

Monitor the differential pressure across the filter element. Replace when DP reaches the manufacturer's recommended

 limit—typically 0.1–0.15 MPa above initial clean pressure drop for natural gas applications. Actual replacement intervals depend 

on gas quality, pipeline age, and upstream contamination levels.

5.3 Storage Conditions

Store unused elements in original packaging in a cool, dry, dust-free environment. Avoid direct sunlight, extreme temperatures, 

and moisture. Recommended storage temperature: 0°C ~ 40°C with relative humidity <70%.

5.4 Disposal

Used elements may contain hydrocarbon residues, condensates, or hazardous contaminants. Follow local environmental

 regulations for disposal—drain any liquid and dispose as industrial waste or through authorized recycling channels.

Frequently Asked Questions (FAQ)

Q1: What is the recommended replacement interval for the CS604LGT2DH13 natural gas filter element?

A: The interval depends on gas quality, pipeline conditions, and upstream contamination levels. Monitor the differential pressure 

gauge—replace when DP reaches 0.1–0.15 MPa above initial clean pressure drop. Under typical operating conditions, 

replacement every 6–12 months or based on DP trend is recommended.

Q2: Can this filter element be cleaned and reused?

A: No. This element is designed for single-use only. Cleaning may damage the media, reduce filtration efficiency, and cause 

media migration—leading to particle breakthrough and downstream equipment damage. Always replace with a new element.

Q3: How do I confirm compatibility with my existing filter housing?

A: Check the model number on your existing element and compare dimensions (outer diameter, inner diameter, length),

 seal type, and flow direction. Our CS604LGT2DH13 follows original specifications for 1:1 interchangeability—no housing

 modifications required. Our technical team can assist with cross-referencing.

Q4: What is the difference between your CS604LGT2DH13 and the original brand element?

A: Our element is manufactured using equivalent high-quality synthetic fiber/coalescing media and premium structural

 components, meeting or exceeding original performance specifications—including ≥99.90% efficiency at 5 μm. It offers

 reliable filtration performance at 40–60% cost savings with faster delivery times.

Q5: What does "filtration efficiency ≥ 99.90%" mean in practice?

A: This means that at the rated 5 μm particle size, the filter captures at least 99.90% of particles. In other words, fewer than 1 

out of 1,000 particles at 5 μm or larger pass through the element. This provides excellent protection for compressors, turbines, 

and other sensitive gas equipment.

Q6: Can this filter element handle natural gas with high liquid loading (wet gas)?

A: The CS604LGT2DH13 is designed primarily for solid particle removal in natural gas streams. For applications with high liquid 

content (water, hydrocarbons, or glycol carryover), we offer coalescing media variants for liquid separation. Please consult our

 technical team for specific wet-gas recommendations.

Q7: What is the operating pressure limit for this element?

A: The CS604LGT2DH13 is rated for maximum working pressure of 6.4 MPa (64 bar). For systems with higher operating pressures,

 we offer custom-engineered elements with enhanced structural strength. Please specify your system pressure when ordering.

Q8: Why is the temperature range limited to –10°C to +50°C?

A: This temperature range covers typical natural gas pipeline operating conditions. For extreme low-temperature or

 high-temperature applications (such as Arctic pipelines or downstream processing facilities), we offer special media and seal 

materials—contact our technical team for customized options.

Q9: Is this element suitable for both onshore and offshore natural gas applications?

A: Yes. The CS604LGT2DH13 is suitable for both onshore and offshore installations, including offshore platforms and FPSO

 facilities. For offshore applications, we recommend specifying corrosion-resistant materials and appropriate seal selection for 

the gas composition.

Q10: Can I use this element for gases other than natural gas?

A: The CS604LGT2DH13 is optimized for natural gas streams. For other gases such as nitrogen, CO₂, hydrogen, or biogas, 

please consult our technical team—different media and material selections may be required based on chemical compatibility 

and operating conditions.

Q11: Can you supply test certificates and documentation for export?

A: Yes. Every shipment includes material certificates, performance test reports, and factory inspection documents. Upon request, 

we can provide third-party inspection reports (additional cost applies) to meet import requirements for various countries.

Q12: Do you keep the CS604LGT2DH13 in stock?

A: Yes. This is one of our popular natural gas filter models and is generally well-stocked. Trial orders (1–10 pcs) ship within 3–7

 working days; bulk orders (500+ pcs) within 15 working days. Expedited shipping is available for urgent requirements.

Q13: Can you customize this filter element for my specific working conditions?

A: Yes. As a source manufacturer, we support full customization—including filtration precision, media type, dimensions, 

seal materials, end-cap designs, and pressure ratings. Please provide your operating conditions and original sample/drawing, 

and we will engineer a tailored solution.

Q14: What happens if the filter element becomes clogged?

A: A clogged element increases differential pressure, which may bypass the element (if a bypass valve is installed), allowing

 unfiltered gas to pass through and risk downstream equipment damage. Without a bypass, high DP may cause element collapse.

 Regular DP monitoring and timely replacement are essential.

Q15: Do you provide technical support for installation or troubleshooting?

A: Yes. Our in-house engineers have extensive experience in natural gas filtration. We provide free dimensional drawings, 

installation guides, and remote video troubleshooting. For large projects, on-site commissioning support can be arranged

 (subject to travel conditions).
