ANSI Standard Coalescer: Engineered Reliability for North American Industrial Applications
Product Introduction
The ANSI Standard Coalescer is a precision-engineered filtration system designed to meet the stringent requirements of ANSI (American National Standards Institute) and industry-specific standards such as API, ASME, and ASTM. Developed for critical applications in natural gas processing, aviation fuel purification, and hydraulic systems, this coalescer ensures reliable separation of water, oil droplets, and particulates while adhering to North American safety, durability, and performance norms.
Certified to ANSI/ASME B31.3 (process piping), ANSI/API 618 (gas compressors), and ANSI/NSF 61 (potable water compliance), this filter is ideal for industries prioritizing North American regulatory compliance, ease of integration with existing infrastructure, and long-term operational stability.
Key Features & Advantages
1. Full ANSI Compliance
Standardized Design: Meets ANSI/ASME B16.5 (flange dimensions), ANSI/API 614 (valve specifications), and ANSI/ASTM D2276 (hydraulic fluid cleanliness).
Material Certifications: 316L stainless steel (ANSI/ASME SA-580) or carbon steel (ANSI/AWS D1.1) with corrosion-resistant coatings for sour gas (H₂S) environments.
2. Exceptional Separation Efficiency
Beta Ratio (β) > 100,000: Removes 99.99% of droplets ≥0.1 μm, including submicron contaminants in aviation fuel and hydraulic oil.
Multi-Stage Customization: Configurable for bulk separation (pre-coalescers) and ultrafine polishing (fine coalescers) to meet ANSI/API 12J (gas dehydration) standards.
3. Robust Construction for Harsh Environments
Pressure Resistance: Rated for 1–300 bar (14.5–4350 psi), with cryogenic variants for LNG (ANSI/ASME B31.12).
Temperature Tolerance: -40°C to +200°C (-40°F to +392°F), with PTFE-coated media for extreme chemical exposure.
4. Energy Efficiency & Cost Savings
Low Pressure Drop (<0.05 bar): Optimized flow paths reduce pumping energy costs by up to 30% compared to non-standard filters.
Longevity: 36–60 months lifespan in industrial environments (vs. 12–24 months for uncertified alternatives).
5. Streamlined Integration
Modular Design: Flanged connections (ANSI/ASME B16.5) and bolt patterns align with North American pipeline standards.
Field Serviceability: Quick-release clamps (ANSI/ASME PCC-1) enable rapid cartridge replacement without specialized tools.
Working Principle
The ANSI Standard Coalescer combines mechanical efficiency with North American engineering standards to achieve superior separation:
1. Fluid Intake & Pre-Filtration
Contaminated fluid (e.g., natural gas, jet fuel) enters through an ANSI/ASME B16.5 flanged inlet, where a cyclonic separator removes large particulates (>10 μm) to protect downstream media.
2. Coalescence Stage
Capture: Submicron droplets (0.1–5 μm) collide with electrostatically charged media fibers (e.g., PTFE-coated glass fiber) due to turbulent flow and van der Waals forces.
Merging: Droplets merge into larger aggregates (50–1000 μm) as they navigate the media’s tortuous pathways, aided by hydrophobic/hydrophilic coatings.
3. Separation & Discharge
Gravity Separation: Enlarged droplets settle at the housing’s sloped base and drain via an automatic float valve (ANSI/ASME B31.1).
Clean Fluid Exit: Purified gas/liquid exits through a high-efficiency membrane (for vapor removal) or stainless steel mesh filter, meeting ANSI/API 12J dehydration standards.
Application Scenarios
1. Natural Gas Processing (Dehydration & Contaminant Removal)
Challenge: Raw natural gas from shale formations contains water vapor and H₂S, risking pipeline corrosion and hydrate formation.
Solution: Removes 99.9% of water/contaminants (β>100,000) while resisting sour gas corrosion (ANSI/ASME B31.3). Complies with API 11D1 for gas pipeline integrity.
2. Aviation Fuel Purification (Jet A/A-1)
Challenge: Jet fuel must meet ANSI/ASTM D1655 (<1 ppm free water, <0.3 μm particulates) to prevent icing and combustion inefficiency.
Solution: Hydrophilic media and FFKM seals ensure <0.5 ppm water removal. Tested to DEF STAN 91-91 and ANSI/API 614, ensuring fuel meets aerospace standards.
3. Hydraulic Systems (Industrial Machinery)
Challenge: Water ingress from washdowns forms emulsions in hydraulic oil, causing pump wear and seal failure.
Solution: Breaks emulsions, reduces water to <10 ppm, and extends oil life by 50%. Modular design allows field upgrades to meet ANSI/NFPA T3.9.1 (fluid power systems).

Maintenance Guidelines
1. Routine Inspection
Differential Pressure (ΔP): Monitor weekly using ANSI/ASME PTC 19.5-compliant gauges; replace media if ΔP exceeds 0.1 bar (initial ΔP: 0.02–0.05 bar).
Visual Checks: Inspect for seal wear or media fouling (monthly) using borescope cameras.
2. Media Replacement
3. Cleaning Protocols
Gas Service: Flush with dry nitrogen (ANSI/CGA G-1.1 purity) to dislodge particulates.
Liquid Service: Soak in a mild detergent solution (pH 7–9) for 30 minutes, followed by high-pressure water jetting.
4. Troubleshooting
Efficiency Drop: Check for chemical incompatibility (e.g., incompatible additives in fuel).
Leaks: Retorque flange bolts to ANSI/ASME PCC-1 torque specs (e.g., 250 ft-lbs for 316L steel).
