Introduction

The PCHG Series Natural Gas Filter Element by XINXIANG LEFILTER® is specifically designed for gas-liquid and liquid-solid separation of natural gas, synthetic gas, and other non-conventional gases (e.g., nitrogen, carbon dioxide). As a core purification component in natural gas transmission pipelines, maintenance stations, distribution stations, and terminal facilities, this series effectively removes contaminants, particulate matter, and pipeline debris, ensuring the safety and stability of gas transmission and exploration while meeting stringent quality requirements for long-distance pipeline transportation.

Product Highlights

• Comprehensive Models: Includes PCHG-12, PCHG-24, PCHG-36, PCHG-312, PCHG-324, PCHG-336, PCHG-358, and PCHG-372, catering to diverse industrial demands.

• High-performance Materials: Utilizes multi-layer composite hydrophilic materials for mechanical impurity interception and water coalescence.

• Rigorous Quality Control: Complies with ISO 2941 (Collapse & Burst Resistant), ISO 2942 (Fabrication Integrity), and other international standards. Every product undergoes strict inspection to ensure reliability.

• Global Applications: Widely used in oil, natural gas, aviation fuel industries, and exported to Russia, Hungary, Iraq, Kazakhstan, and more.

Applications

The PCHG Series is ideal for:

• Natural Gas Transmission Pipelines: Protects compressors, valves, and critical equipment from particulate damage.

• Maintenance & Distribution Stations: Ensures gas purity during transportation.

• Terminal Facilities & Storage Systems: Guarantees safe and high-quality gas for end-users.

• Industrial Gas Processing: Suitable for nitrogen, carbon dioxide, and other non-natural gas purification.

Working Principle

The PCHG Series achieves efficient purification through multi-stage filtration and coalescence technology:

1. Primary Filtration: High-precision filter media captures solid particles, rust, and mechanical impurities.

2. Coalescence: Hydrophilic materials aggregate tiny liquid droplets into larger ones for easy separation.

3. Secondary Separation: Gravity or centrifugal force ensures complete gas-liquid separation, delivering clean, dry gas.
