Introduction

The Natural Gas Filter Element Model PCHG-36, manufactured by Xinxiang Filter (Stock Code: 837936), is a high-performance filtration solution designed for gas-liquid and liquid-solid separation in natural gas, artificial gas, and other non-corrosive gases. Certified to ISO standards and trusted by global clients like Petrobras and ExxonMobil, the PCHG-36 ensures operational safety, efficiency, and compliance with stringent industry requirements. Ideal for aviation, oil & gas, and industrial applications, this filter guarantees purity and reliability in critical systems.

Product Structure

The PCHG-36 features a robust multi-layered design engineered for durability and precision:

• Core Material: Hydrophobic PTFE-coated stainless steel mesh (water-repellent, gas-permeable).

• Support Layers: Reinforced center tube, pleated fiberglass, and primary filter felt for structural integrity.

• Seals: High-temperature silicone gaskets for leak-free performance.

• Dimensions: Customizable OD (60–200 mm), ID (30–100 mm), and length (200–1200 mm).

Application in the Aviation Industry

The PCHG-36 is critical for aviation fuel systems, ensuring:

• Jet Fuel Purification: Removes particulates and emulsified water from aviation kerosene, meeting ASTM D1655 standards.

• Hydraulic Fluid Protection: Safeguards aircraft systems from contamination.

• Case Study: A 2022 order for Taiwan military aviation fuel purification utilized PCHG-series filters (OD152*ID89mm), achieving 99.9% efficiency.

Other Industry Applications

• Natural Gas Transmission: Protects compressors and pipelines at transmission stations and dehydration towers.

• Oil & Gas Processing: Used in fuel gas systems and refinery compressor suction lines.

• Chemical Plants: Separates hydrocarbons and non-corrosive gases.

• Marine: Ensures clean fuel for ship engines and offshore platforms.

Key Advantages

1. ISO-Certified Quality: Complies with ISO 2941 (burst resistance), ISO 2942 (integrity testing), and CE standards.

2. High Efficiency: ≥99.9% filtration efficiency at 10 μm.

3. Customizable Design: Tailored dimensions and pressure ratings (0.5–25 MPa).

4. Global Trust: Used by ExxonMobil, Petrobras, and Sany Heavy Industry across 128+ countries.

Working Principle

1. Filtration: Solid particles (rust, debris) are trapped by multi-layered media.

2. Coalescence: Microscopic liquid droplets merge into larger ones within hydrophilic layers.

3. Separation: Hydrophobic mesh repels water, allowing purified gas to flow. Gravity settles separated liquids into collection chambers.
