FAQs of The Sintered Filter

Q1: What is the filtration accuracy range?

A1: Filtration accuracy ranges from 0.5μm to 300μm, fully customizable based on your specific application requirements. Common accuracies include 1μm, 5μm, 10μm, 20μm, 25μm, 40μm, 75μm, 100μm, and 200μm.

Q2: What is the difference between flange and threaded connections for this filter?

A2:

• Flange connections distribute clamping force evenly across the sealing surface, minimizing stress on the sintered filter body. This makes them ideal for high-pressure, high-temperature, and corrosive applications where seal integrity is critical. The bolted design prevents leakage better than threaded or O-ring seals, especially under thermal cycling.
• Threaded connections are mechanically strong and familiar but create stress concentrations at the thread base. Over-tightening can generate cracks in the sintered metal housing, and repeated installation/removal wears down threads, compromising the seal.

Recommendation: Choose flange for harsh conditions where reliability is paramount; choose threaded for standard applications with moderate conditions and infrequent maintenance.

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.

Q5: What is the difference between 304 and 316L stainless steel for filter elements?

A: 304 stainless steel offers good corrosion resistance and is cost-effective for most general industrial applications.

316L stainless steel contains 2-3% molybdenum, providing superior corrosion resistance to chlorides, acids, and alkalis, making it the preferred choice for marine, offshore, and highly corrosive chemical environments.

Choose 304 for general applications and 316L for demanding corrosive environments.

Q6: Can the filter be customized for non-standard equipment?

A: Absolutely. Huahang Filter offers design support for special size or performance requirements. Customization options include filtration accuracy, non-standard lengths and diameters, custom end caps, flanges, threads, and alternative alloys.
