High-Temperature Resistant PP Wound Filter Cartridge: Deep Filter Cartridge for High-Temperature Process Water Circulation Purification
Product Introduction
This high-temperature resistant PP wound filter cartridge is a professional high-performance deep filtration component exclusively engineered for the circulation purification of high-temperature process water in industrial production, tailored to the harsh operating conditions of high-temperature, high-pressure and continuous circulation in petrochemical, metallurgical, power generation and advanced manufacturing industries. Crafted from modified high-temperature resistant polypropylene (PP) resin via a high-precision dense spiral winding process on a reinforced heat-stable PP inner support core, it features an adhesive-free integral forming structure and a graded porous deep filtration layer optimized for high-temperature fluid dynamics. Its core function is to perform deep and efficient removal of insoluble solid particulate impurities such as scale debris, metal oxide particulates, sediment, rust and mechanical wear particles from high-temperature process water (80℃-120℃) in closed circulation systems, preventing pipeline scaling, heat exchanger fouling, precision equipment wear and circulation pump impeller damage, thus improving the heat exchange efficiency of industrial systems, reducing energy consumption and ensuring the stable and continuous operation of high-temperature production processes. Compliant with industrial high-temperature water treatment material standards, it exhibits excellent structural stability, thermal resistance and chemical compatibility under long-term high-temperature circulation conditions, causes no secondary pollution to the high-temperature process water and no thermal decomposition of filter materials, and is an indispensable deep filtration core for the purification of high-temperature process water circulation systems in various industrial sectors with high-temperature production demands. The cartridge is compatible with standard large-diameter filter housings for high-temperature fluid filtration, realizing direct and reliable replacement in industrial circulation systems.
Filtration Precision
This high-temperature resistant PP wound filter cartridge offers a range of nominal absolute filtration precision options from 1μm to 50μm, all scientifically calibrated and optimized for deep filtration of high-temperature process water, with each precision grade maintaining stable interception performance under 80℃-120℃ high-temperature conditions without precision deviation caused by thermal expansion or structural deformation. The 1μm/5μm high-precision options achieve over 99% deep interception of micro-scale particulate impurities, suitable for high-precision high-temperature process water circulation systems in aerospace component processing, semiconductor manufacturing and high-end equipment production, ensuring the removal of ultra-fine contaminants that damage precision molds and processing equipment; the 10μm/20μm medium-precision options (the most commonly used for industrial general high-temperature process water) realize 98%+ deep filtration of medium and coarse particulates, applicable to high-temperature circulation water systems in petrochemical refining, steel smelting and power plant boiler feed water pretreatment, balancing deep impurity removal and high-temperature circulation flux demand; the 30μm/50μm coarse-precision options are designed for heavy-impurity high-temperature process water in metallurgical smelting and building material production, performing deep interception of bulky solid contaminants to reduce the load of high-temperature circulation systems and avoid rapid filter cartridge fouling. All precision grades adopt a deep filtration structure with multi-layer graded pore size distribution, which not only ensures the high interception efficiency of particulate impurities of different sizes, but also forms a large-capacity impurity storage space inside the filtration layer, adapting to the long-term continuous circulation characteristics of high-temperature process water systems and avoiding frequent replacement of filter cartridges.
Flux
Under the standard high-temperature industrial operating conditions of 100℃ ambient temperature and 0.3MPa inlet pressure (the typical working condition of industrial high-temperature process water circulation systems), the nominal flux of this high-temperature resistant PP wound filter cartridge is calibrated and optimized for high-temperature fluid characteristics, with flux performance matched with filtration precision and deep filtration structure, and the flux is stably maintained without significant attenuation under 80℃-120℃ temperature variation. For the mainstream industrial precision grades adapted to high-temperature process water circulation, the nominal flux of a single cartridge is as follows: 1μm (20-25 L/min), 5μm (30-35 L/min), 10μm (45-50 L/min), 20μm (60-70 L/min), 30μm (75-85 L/min), 50μm (90-100 L/min). The modified high-temperature resistant PP material and optimized internal flow channel structure effectively reduce the viscosity resistance of high-temperature process water in the filtration layer, ensuring that the cartridge maintains a high and stable flux level even under the high-precision 1μm/5μm configuration and 120℃ extreme high temperature. For large-scale high-temperature process water circulation systems, the total system flux can be linearly scaled up by increasing the number of cartridges in parallel in high-temperature resistant multi-core filter housings, meeting the ultra-large-flow circulation purification demands of industrial production lines such as large-scale power plants and petrochemical refineries. The flux of the cartridge remains stable throughout the service life, and the deep filtration structure delays the flux attenuation caused by impurity accumulation, ensuring that the flow rate of the high-temperature process water circulation system matches the industrial production load demand and avoiding the reduction of heat exchange efficiency due to insufficient circulation flow.
Salt Rejection Rate
As a professional deep filtration component dedicated to the purification of high-temperature process water circulation systems, this high-temperature resistant PP wound filter cartridge—regardless of the selected filtration precision (1μm-50μm)—is designed exclusively for particle size-based deep interception of insoluble solid contaminants (scale debris, metal oxides, sediment, rust) in high-temperature process water. It is not designed with ion separation, desalination or soluble salt removal functions, and the modified high-temperature resistant PP material has no selective adsorption or rejection effect on dissolved salts in high-temperature water. Therefore, this product has no salt rejection rate index for all precision grades and all operating temperature ranges (80℃-120℃). All dissolved inorganic salts, metal ions, small molecule soluble substances, high-temperature water treatment agent residuals and dissolved solids (TDS) in the high-temperature process water pass smoothly through the filter cartridge body and remain in the circulation system, which is consistent with the operational requirements of industrial high-temperature process water circulation systems—most industrial high-temperature production processes require the maintenance of specific ion concentrations and chemical properties of process water, and the filter cartridge will not alter the soluble ion composition and chemical balance of the high-temperature process water, avoiding unnecessary interference with the industrial production process and ensuring that the filtered high-temperature process water fully meets the technological requirements of production.
Pressure Drop
The pressure drop performance of this high-temperature resistant PP wound filter cartridge is specially optimized for the high-temperature, high-pressure circulation characteristics of industrial process water, with the initial pressure drop strictly controlled and the pressure drop rise rate slowed down via the deep filtration structure, ensuring minimal pressure loss of the high-temperature circulation system while maintaining deep filtration efficiency. Under the standard operating conditions of 100℃ and 0.3MPa inlet pressure, the initial pressure drop for all filtration precision grades is ≤0.035MPa; the coarse-precision grades (30μm/50μm) have an even lower initial pressure drop (≤0.025MPa) due to the looser deep filtration layer structure, while the high-precision grades (1μm/5μm) maintain a low initial pressure drop via the optimized high-temperature flow channel design, avoiding excessive pressure loss in the high-temperature process water circulation system and reducing the energy consumption of high-temperature circulation pumps. The recommended maximum allowable operating pressure drop for all precision grades is 0.25MPa, a heavy-duty design adapted to the high-temperature, high-pressure continuous circulation operation—this higher limit effectively extends the service life of the filter cartridge under high-temperature and high-impurity conditions. With the continuous operation of the high-temperature circulation system, particulate impurities are deeply intercepted and accumulated in the multi-layer graded filtration layer, leading to a slow and stable rise in pressure drop; the deep filtration structure disperses the impurity accumulation throughout the filtration layer instead of only on the surface, significantly delaying the pressure drop rise rate and ensuring stable pressure operation of the high-temperature circulation system. When the pressure drop reaches 0.25MPa, the filter cartridge can be cleaned or replaced in a unified manner during scheduled production downtime, and delayed replacement within a short period will not cause significant impact on the normal operation of the high-temperature circulation system, fully adapting to the actual maintenance habits of industrial high-temperature production.
Molecular Weight Cutoff (MWCO)
This high-temperature resistant PP wound filter cartridge—for all filtration precision grades (1μm-50μm) and all operating temperatures (80℃-120℃)—adopts a pure physical deep filtration mechanism based on particle size interception for high-temperature process water. Its core working principle is to capture insoluble solid particulate impurities in high-temperature fluid according to their actual physical particle size through the multi-layer graded pore size structure of the filtration layer, rather than separating substances based on molecular weight, molecular size or chemical composition. This is fundamentally different from ultrafiltration (UF), nanofiltration (NF) and reverse osmosis (RO) membrane components with specific Molecular Weight Cutoff (MWCO) indexes, which are rarely used in high-temperature process water systems due to their poor thermal resistance. Therefore, this product has no specific MWCO index for any precision grade, operating temperature or application scenario. The deep interception effect is only targeted at solid particulates with a particle size larger than the selected filtration precision; macromolecular organic substances, soluble colloids, dissolved polymers and other dissolved substances in the high-temperature process water can pass through the filter cartridge body smoothly as long as their actual particle size is smaller than the filtration precision, and remain in the circulation system to maintain the chemical properties of the process water. This design fully meets the functional requirements of high-temperature process water circulation purification: focusing on the deep and efficient removal of physical particulate impurities that cause system fouling and equipment damage in high-temperature fluid, without participating in the molecular-level purification of the water body, and the abandonment of MWCO-related design further enhances the structural stability and thermal resistance of the filter cartridge, making it more adaptable to the harsh high-temperature operating environment of industrial circulation systems.
Membrane Thickness
The effective high-temperature resistant PP filtration layer thickness of this filter cartridge is heavy-duty optimized and matched with filtration precision and deep filtration structure, with a thickness range of 15mm to 35mm—significantly thicker than conventional PP wound filter cartridges—designed to withstand the high-temperature, high-pressure scouring of industrial process water circulation and ensure sufficient deep impurity holding capacity and structural stability under thermal expansion. The thickness is scientifically graded according to filtration precision and deep filtration demand: the 1μm/5μm high-precision grades feature the thickest filtration layer (25mm-35mm), forming an ultra-dense multi-layer graded deep filtration structure with micro-scale pore size distribution, which not only ensures the deep interception of ultra-fine impurities in high-temperature process water, but also provides an oversized internal impurity storage space to avoid rapid blockage under long-term high-temperature circulation; the 10μm/20μm medium-precision grades (mainstream industrial options for high-temperature process water) have a moderate heavy-duty thickness (20mm-30mm), balancing deep filtration density, high-temperature flux performance and impurity holding capacity, adapting to the general circulation purification demand of most industrial high-temperature process water systems; the 30μm/50μm coarse-precision grades have a thickened deep filtration layer (15mm-25mm) with a graded loose porous structure, optimizing the internal high-temperature flow channel space for maximum large-flow filtration while ensuring the deep interception of bulky impurities and anti-scouring performance under high temperature. The inner support core is reinforced and thickened to 7mm-9mm (honeycomb heat-stable structure) for all precision grades, made of modified high-temperature resistant PP material with low thermal expansion coefficient, able to withstand the operating pressure of up to 1.2MPa and temperature of 120℃ in high-temperature process water circulation systems without deformation, rupture or filtration layer displacement, ensuring the structural integrity and filtration precision stability of the filter cartridge under extreme high-temperature conditions. The total outer diameter and length of the filter cartridge are manufactured in accordance with the universal dimensional specifications of industrial high-temperature fluid filter housings, ensuring a perfect fit with the housing’s internal structure, no high-temperature water short-circuit during installation, and tight sealing with the housing’s high-temperature resistant end cap.
Replacement Cycle
The replacement cycle of this high-temperature resistant PP wound filter cartridge is a heavy-duty design adapted to the long-term continuous circulation operation of industrial high-temperature process water systems, and is comprehensively determined by the selected filtration precision, the impurity content of the high-temperature process water, and the operating temperature (80℃-120℃), with an extended service life to reduce the maintenance frequency and downtime of high-temperature production processes. For the 1μm/5μm high-precision grades used in low-impurity, high-precision high-temperature process water circulation systems (e.g., semiconductor manufacturing, aerospace component processing) operating at 80℃-100℃, the replacement cycle is 5-7 months; for the same high-precision grades operating at 100℃-120℃ extreme high temperature with slightly higher impurity content, the cycle is 4-5 months. For the 10μm/20μm medium-precision grades (the most widely used for industrial general high-temperature process water) in circulation systems for petrochemical refining, power plant boiler feed water and steel smelting (medium impurity content, 80℃-110℃ continuous circulation operation), the standard replacement cycle is 6-9 months—this extended cycle is achieved via the ultra-thick deep filtration layer and oversized impurity storage space, which significantly improve the anti-fouling capacity of the filter cartridge under high-temperature conditions. For the 30μm/50μm coarse-precision grades used in high-impurity, high-turbidity high-temperature process water circulation systems (e.g., metallurgical smelting, building material production) operating at 90℃-120℃ continuous heavy load, the replacement cycle is 7-10 months, as the graded loose deep filtration structure and large flux reduce the impurity accumulation rate and high-temperature scouring damage. The actual replacement cycle can be appropriately extended by 1-2 months for high-temperature process water with low turbidity and low suspended solid content (SS ≤10 mg/L); for high-impurity high-temperature water (SS ＞25 mg/L), the cycle is shortened by 1 month. All precision grades support repeated physical backwashing (high-pressure high-temperature clean water rinsing/compressed air blowing), a design adapted to industrial high-temperature process water circulation systems with built-in backwash systems—backwashing can remove 60%+ of deep accumulated impurities in the filtration layer, extending the replacement cycle by an additional 2-3 months and greatly improving the cost performance of the filter cartridge under high-temperature operating conditions. In actual industrial operation, the replacement cycle is also determined by the pressure drop of the high-temperature circulation system: when the pressure drop reaches the recommended maximum of 0.25MPa or the system circulation flow rate is significantly reduced, the filter cartridge is replaced in a unified manner during scheduled production downtime, avoiding unplanned shutdowns of high-temperature production processes and ensuring continuous and stable industrial production.
