304 Stainless Steel Sintered Mesh Filter 35×130

Huahang Filter is a specialized manufacturer with deep expertise in sintering technology and industrial filtration solutions. Our focus is on engineering reliable, high-performance metal filters. We control the manufacturing process from raw material selection to final quality testing, ensuring each element meets precise specifications for pore size, strength, and durability. Our team supports customers with technical selection and customization to ensure the filter integrates seamlessly and performs reliably in your specific application.

Our manufacturing facility is equipped with advanced vacuum sintering furnaces, precision welding equipment, and dimensional testing instruments, all operated by experienced technicians dedicated to producing filtration components of the highest international standard. We do not simply resell stock filters – we engineer and manufacture each custom element from raw materials to finished product, ensuring full control over quality, lead time, and cost.

Why Choose Huahang Filter

• Advanced Sintering Process Control: We precisely control temperature, atmosphere, and pressure during the sintering process to create a uniform, three-dimensional porous structure with consistent pore size distribution.
• Superior Stainless Steel Material Integrity: Utilizing certified stainless steel wire mesh, we offer exceptional corrosion resistance, particularly against chlorides and acidic environments.
• Precision Engineering for Guaranteed Fit: We meticulously manufacture to exact dimensional specifications, ensuring the filter fits perfectly in designated housings. Our commitment to precision extends to end cap bonding, seal interfaces, and overall concentricity.
• Robust Construction for Demanding Environments: The diffusion-bonded monolithic structure provides exceptional mechanical strength, resistance to thermal cycling, and the ability to withstand high differential pressures without collapse or deformation.
• Comprehensive Customization Capability: Beyond standard sizes, we specialize in custom sintered components. Our engineering team can develop elements with specific micron ratings, dimensions, connection types, and material grades to meet unique application requirements.

What Does This Conical Sintered Mesh Filter Remove

When installed in a filtration system, this custom 173×152 conical sintered mesh filter element effectively removes:

• Carbonized Particles and Gels (Polymer Melts) : Thermally degraded polymer residues that cause filament breaks, surface defects, and optical imperfections in films and fibers.
• Metal Fines and Wear Debris : Microscopic metallic particles from pumps, compressors, gearboxes, and upstream processing equipment.
• Catalyst Fines : Sub‑micron metallic catalyst particles in chemical and petrochemical streams that degrade product purity or catalyze unwanted side reactions.
• Filler Agglomerates : Undispersed additive particles (TiO₂, carbon black, talc, flame retardants) that create surface defects.
• Foreign Particulates : Dirt, dust, scale, pipe debris, and other solids introduced during material handling or processing.
• Abrasive Solids in Slurries : Hard particles that would otherwise damage downstream pumps, valves, and heat exchangers.
• Rust and Scale : Corrosion products from pipelines and storage vessels.
• Suspended Solids : Miscellaneous solid contaminants suspended in liquid or gas streams.

FAQs of The Sintered Filter

Q1: Is this filter element suitable for high-pressure applications?
A1: Yes. The sintered metal construction provides high mechanical strength and pressure resistance. The element can withstand operating pressures up to 35 MPa (depending on configuration), making it suitable for high-pressure hydraulic and process applications.

Q2: What is the best method to clean this filter, and how do I know it’s clean?
A2: For most applications, ultrasonic cleaning followed by a clean water or solvent rinse is highly effective for removing embedded particles. Backflushing with clean compressed air or liquid is also common. A well-cleaned filter will restore its initial, clean pressure drop when tested with a clean fluid. A significant, irreversible pressure drop indicates the end of its usable life.

Q3: Can you provide customized sintered filter?
A3: Yes. We can not only provide the standard size, but also the customized filters. We routinely modify end cap designs (e.g., add NPT threads, O-ring grooves, or flanges) and can adjust the overall length or even the filtration rating to meet your specific system integration requirements and performance goals.

Q4: How does the number of sintered layers affect filtration performance, pressure drop, and cleanability?
A: More layers increase:

Mechanical strength – Additional reinforcing layers improve collapse pressure .

Dirt‑holding capacity – Depth loading increases as more layers are added, extending service life before cleaning.

Pressure drop – Each additional layer adds resistance; typically 5‑10% ΔP increase per layer.

Fewer layers offer lower ΔP but less strength and dirt‑holding. Standard recommendation for 30×100: 5‑layer (protective + control + dispersion + 2 reinforcing) balances all factors. Use 7‑layer only for high‑pressure or high‑abrasion applications; use 3‑layer for low‑pressure, high‑flow, clean service.
