As a trusted manufacturer since 1998, Anping County Boli Hardware Wiremesh Products Factory specializes in high-performance sintered powder filter tubes engineered for demanding metal fly ash treatment and liquid gas filtration applications. Our deep expertise in powder metallurgy ensures that every filter tube delivers consistent porosity, excellent mechanical strength, and long service life. Whether you need to remove fine particles from hot gas streams or purify liquids in chemical processes, our sintered metal filters provide a reliable solution that reduces downtime and maintenance costs.
The sintered powder filter tube is manufactured by compacting and sintering stainless steel powder under high temperature and pressure, creating a rigid porous structure with interconnected pores. This design offers superior filtration efficiency, high dirt-holding capacity, and excellent resistance to thermal shock and corrosion. The tube can be easily cleaned by backwashing, ultrasonic cleaning, or thermal regeneration, making it ideal for continuous operation in harsh environments.
Key Features & Technical Specifications
- High Filtration Precision: Available from 0.5 μm to 100 μm, ensuring effective capture of fine particles in metal fly ash and liquid gas streams.
- Robust Mechanical Strength: Withstands high differential pressure and mechanical stress, suitable for high-flow and high-pressure applications.
- Excellent Thermal Stability: Operates continuously at temperatures up to 600°C (higher on request), ideal for hot gas filtration.
- Corrosion & Chemical Resistance: Made from stainless steel 304/316L or other alloys, resistant to acidic, alkaline, and organic solvents.
- Customizable Dimensions: Outer diameter from 10 mm to 200 mm, length up to 1500 mm, with various connection types (thread, flange, or custom).
- Regenerable: Can be cleaned and reused multiple times, reducing replacement costs and waste.
- Uniform Porosity Distribution: Ensures stable filtration performance and predictable pressure drop.

Our filter tubes are widely used in metal smelting, waste incineration, chemical processing, oil & gas, and pharmaceutical industries. For example, in metal fly ash treatment, the tube effectively traps fine particulate matter while allowing hot gases to pass, enabling compliance with environmental regulations. In liquid gas filtration, it removes solid contaminants from cryogenic or high-pressure gas streams, protecting downstream equipment and ensuring product purity.
With over 20 years of manufacturing experience and an annual export value of US$5 million to US$10 million, our factory serves clients across North America, South America, Europe, Asia, Africa, and Oceania. We ship from major ports like Tianjin, Qingdao, Shanghai, and Foshan, ensuring timely delivery. Our commitment to quality and customer satisfaction has made us a preferred partner for filtration solutions worldwide.
We invite you to contact us for free samples, technical datasheets, or customized solutions. Our team is ready to assist you in selecting the optimal sintered powder filter tube for your specific metal fly ash or liquid gas filtration application. Experience the reliability and performance that only a dedicated manufacturer can provide.
Frequently Asked Questions
-
Q: What is the maximum operating temperature of your sintered powder filter tubes?
A: Standard tubes can handle up to 600°C. For higher temperature requirements (up to 900°C), we can customize the material and sintering process. Please specify your temperature range when inquiring. -
Q: How can I clean the filter tube?
A: The tube can be cleaned by backwashing with compressed air or liquid, ultrasonic cleaning, or thermal regeneration (burning off organic residues). The specific method depends on the type of contaminants. We provide cleaning guidelines upon request. -
Q: Can I get custom dimensions or connection types?
A: Absolutely. We offer full customization of outer diameter, length, wall thickness, and connection types (thread, flange, male/female ends, etc.). Just provide your drawing or specifications. -
Q: What materials are available besides stainless steel?
A: We can produce filter tubes from various alloys, including Hastelloy, Inconel, Monel, titanium, and others. Tell us your chemical environment, and we will recommend the best material. -
Q: What is the typical pressure drop across the filter tube?
A: Pressure drop depends on flow rate, viscosity, filtration grade, and tube geometry. For a 10 μm tube at typical air flow, initial pressure drop is around 0.01–0.05 MPa. We can provide calculation tools or test data for your specific conditions. -
Q: Do you provide samples for testing?
A: Yes, we offer free samples of standard sizes. You only need to cover shipping costs. Contact our sales team to arrange a sample for your trial. -
Q: What is the lead time for bulk orders?
A: Typical lead time is 15–30 working days, depending on quantity and customization. For urgent orders, we can expedite production upon request. -
Q: Are your filter tubes suitable for food or pharmaceutical applications?
A: Yes, when made from 316L stainless steel and with appropriate surface treatment, our tubes meet hygiene standards for food and pharmaceutical filtration. We can provide a certificate of material compliance.
