As a trusted manufacturer from Anping County Boli Hardware Wiremesh Products Factory, established in 1998, we specialize in producing high-quality filtration solutions. Our High Temperature Porous Sintered Metal Filter is engineered to withstand extreme conditions up to 800°C, made from premium 316L stainless steel, and offers a precise 5-micron filtration rating. Designed specifically for chemical processing applications, this filter delivers reliable performance, long service life, and excellent resistance to corrosion and thermal shock. With annual export values between US$5 Million and US$10 Million, we serve global markets including North America, Europe, Southeast Asia, and the Middle East, ensuring consistent quality and competitive pricing.
Product Overview: This sintered metal filter element is fabricated through a high-temperature sintering process that bonds 316L stainless steel powder into a porous structure. The result is a robust, homogeneous filter medium with controlled porosity, ideal for filtering aggressive chemicals, high-temperature gases, and viscous fluids. Its ability to operate at 800°C makes it suitable for petrochemical, pharmaceutical, and industrial gas processing where traditional filters fail.
- Material: 316L stainless steel – excellent corrosion resistance against acids, alkalis, and chlorides.
- Temperature Resistance: Continuously up to 800°C in oxidizing atmospheres; higher for inert environments.
- Filtration Precision: 5 micron nominal rating with high dirt-holding capacity and consistent pore size distribution.
- Mechanical Strength: High compressive and tensile strength, withstands pressure differentials up to 20 bar.
- Chemical Compatibility: Suitable for most organic solvents, weak acids, and bases at elevated temperatures.
- Regenerative Capability: Can be cleaned by backwashing, ultrasonic, or thermal regeneration, extending service life.

Key Advantages for Chemical Processing: This filter excels in environments where high temperature, corrosive media, and fine particulate removal are critical. The sintered structure provides a uniform pore network that prevents bypass and ensures consistent filtration efficiency. Compared to wire mesh or ceramic filters, our 316L sintered metal filter offers superior mechanical integrity and thermal shock resistance. It can be fabricated into various shapes – tubes, discs, plates, and custom geometries – to fit existing reactor vessels, pipelines, and filtration housings. The smooth surface finish reduces fouling and facilitates cleaning, minimizing downtime.
Quality Assurance: Every filter element undergoes rigorous testing for bubble point, flow rate, and burst pressure to meet international standards. Our factory in Hengshui, Hebei, China, operates with over 20 years of experience in wire mesh and sintered metal products. We ship from major ports including Tianjin, Qingdao, Shanghai, and Foshan, ensuring timely delivery worldwide.
Frequently Asked Questions (FAQ):
- Can this filter handle thermal cycling from room temperature to 800°C? Yes, the sintered 316L structure has excellent thermal fatigue resistance. However, gradual heating and cooling are recommended to avoid extreme thermal shock.
- How do I clean the filter after use? Common methods include backflushing with clean solvent, ultrasonic cleaning, or high-temperature oxidation (burn-off) in air at 500-600°C. Always check chemical compatibility first.
- What is the typical lifespan of this filter element? Depending on the application and cleaning frequency, it can last from 6 months to several years. The regenerable nature significantly extends service life.
- Is the 5 micron rating absolute or nominal? It is a nominal rating, but the pore size distribution is narrow. For absolute ratings, we can provide custom grades from 1 to 100 microns.
- Can I use this filter for hydrogen gas at high temperature? 316L SS is suitable for hydrogen service up to 800°C, but hydrogen embrittlement may occur above 400°C under high pressure. Please consult our engineering team for specific conditions.
- Do you offer custom shapes or flanged connections? Yes, we can produce filter elements in various shapes and with threaded, flanged, or welded connections. Contact us with your requirements.
- What is the maximum pressure rating? Standard elements withstand up to 20 bar differential pressure. Higher pressure ratings are available upon request.
- Are there any certifications for this product? Our manufacturing process follows ISO 9001 quality management principles. Specific certifications (e.g., ATEX, FDA) can be quoted based on your application.
