316L stainless steel liquid melt pre-filtration pleated folding strainer is a precision filtration device designed specifically for high-temperature, high-viscosity fluids. Utilizing 316 stainless steel and multi-layer sintered mesh technology, it effectively intercepts solid particles from oil, fuel, and polymer melts. Its modular structure allows for quick disassembly and cleaning, and it offers corrosion resistance, high strength, and a long lifespan. It is widely used in the petroleum, chemical, mechanical lubrication systems, and new energy sectors.
Technical parameters: • Filtration accuracy: 2μm–300μm • Temperature range: -20°C–650°C • Working pressure: ≤0.6MPa (static) • Powder holding capacity: ≥800g/m² • Connection size: DN15–DN200 • Material: 316 stainless steel • Cleaning method: Backwash, high-pressure steam cleaning
Filter Material: The 316L stainless steel liquid melt pre-filtration pleated folding strainers we produce have excellent filtration quality. The diameter, length and other dimensions can be customized according to actual needs. • A surface passivation film resists corrosion and prevents secondary contamination (ASTM A240 certified). • The high-ductility braiding process achieves a strength of 300 MPa, resisting fluid impact without deformation. • The filter and mounting plate are connected via bolts or threads, enabling quick replacement. 
Applications: ✅ Petrochemical: Filter asphaltene and colloids during crude oil refining to ensure pipeline flow. ✅ Chemical Fiber Production: Filter gels and black specks during PET film extrusion to improve film clarity. ✅ Food and Pharmaceutical: Remove suspended impurities during edible oil refining to meet FDA food contact standards. ✅ Recycling: Filter metal debris and unmelted particles during plastic recycling and pelletizing to improve the quality of recycled materials.
