Superior Chemical Resistance: Unaffected by most mild acids, alkalis, solvents, and organic compounds, PE filter tubes maintain structural integrity in harsh chemical environments. Unlike metal filters, they do not corrode or leach harmful substances, ensuring filtrate purity .
Precise Filtration Accuracy: With pore sizes controllable from 0.1μm to 140μm, PE filter tubes effectively capture solid particles of varying sizes. The fine, tortuous pore channels ensure high retention rates (over 99% for target particles) and clear filtrate, even for sub-micron contaminants once a filter cake forms .
Excellent Mechanical Stability: As rigid porous components, PE filter tubes resist deformation under pressure and temperature (up to 80℃ for PE, vs. 120℃ for PA variants). They withstand backwashing with compressed air or water, enabling easy slag removal—even for viscous filter cakes .
Reusable & Cost-Effective: Unlike disposable filters, PE filter tubes can be regenerated repeatedly via backwashing or chemical cleaning, significantly extending service life and reducing replacement costs. Their lightweight design also lowers installation and handling expenses .
Compliance & Safety: Made from 100% virgin resin, PE filter tubes meet FDA, NSF 51, and NSF 61 standards, making them safe for food contact, potable water, and pharmaceutical applications .
Sintered Powder PE Filter Tubes: Manufactured from compressed PE powder, these tubes feature high porosity and large throughput capacity. Ideal for industrial liquid filtration with high solid content.
Sintered Spherical PE Filter Tubes: Constructed from spherical PE particles, they offer uniform pore size distribution, minimizing clogging. Perfect for laboratory and pharmaceutical critical filtration tasks.
Tubular Sintered PE Filter Tubes: Designed for continuous filtration processes, their tubular structure ensures smooth fluid flow and consistent performance. Widely used in industrial continuous production lines.
Sintered PE Felt Filter Tubes: Made from sintered PE fibers, they boast high dirt-holding capacity and long service life. Suitable for chemical and petrochemical liquid filtration.
Material | Chemical Resistance | Upfront Cost | Maintenance | Suitability |
|---|---|---|---|---|
PE | Excellent (mild acids/alkalis) | Low | Reusable via backwashing | Low-temperature, corrosive environments |
Stainless Steel | Good (limited by strong acids) | High | Requires chemical cleaning | High-pressure, high-temperature applications |
Bronze | Poor (corrodes at pH <5.5) | Moderate | Frequent re-oiling | Neutral, low-corrosion environments |
PA | Good | Moderate | Reusable | High-temperature (up to 120℃) tasks |
Use compressed air (or air-water mixture) for backwashing to remove filter cakes. Adjust pressure based on tube specifications to avoid damage .
For heavy fouling, use mild chemical cleaners compatible with PE (avoid oxidative acids like nitric acid).
Operate within recommended temperature (<80℃) and pressure limits to prevent deformation.
Regularly inspect for cracks or blockages, especially in high-viscosity applications (viscosity <30 cp is preferred) .
