1μm Flange Sintered Powder Filter Element Huahang Filter Supply

Description:

The Flange Sintered Powder Filter Element is a high-precision all-metal filtration component created through advanced powder metallurgy and high-temperature vacuum sintering technology. With its 140mm outer diameter and 260mm length, this element delivers exceptional particle retention performance in a robust, easy-to-integrate package, making it a versatile choice for demanding industrial applications.

The defining feature of this filter element is its flange connection—a bolted mounting interface specifically engineered for high-pressure, high-temperature, and corrosive applications where seal integrity is non-negotiable. Unlike standard 222/226 O-ring or threaded connections, the flange interface uses bolts to secure the filter element directly to the pipeline flange, providing superior sealing strength and structural integrity under the most demanding operating conditions. This makes the flange sintered powder filter the ideal choice for pipelines carrying hazardous media or operating at extreme pressures.

Feature：

Flange Connection for Harsh Environments: The bolted flange mounting interface is specifically designed for high-pressure, high-temperature, and corrosive applications where seal integrity is paramount. Flanged interfaces typically use standard flange sizes and mounting hole patterns, and provide superior sealing strength compared to threaded or O-ring interfaces, making this element ideal for pipeline systems handling hazardous or high-value media.
High-Precision Powder Sintered Construction: Manufactured from high-purity stainless steel powder (304 or 316L) through precision powder metallurgy and high-temperature vacuum sintering, creating a rigid, homogeneous porous structure with a three-dimensional network of interconnected pores.
Wide Filtration Precision Range: Available filtration precision from 0.2μm to 200μm, enabling customized particle retention for applications ranging from ultra-fine pharmaceutical sterile filtration to coarse pipeline debris straining.
Exceptional High-Temperature Resistance: Operates reliably up to 600°C in normal use, with some configurations capable of withstanding up to 900°C for short-term gas filtration applications, making it suitable for high-temperature gas purification and process streams.
High Mechanical Strength and Good Plasticity: The sintered structure provides excellent mechanical strength and can be machined after sintering, allowing for custom modifications to meet specific installation requirements.
Excellent Corrosion Resistance: 304 or 316L stainless steel construction offers outstanding resistance to nitric acid, sulfuric acid, dilute hydrochloric acid (5%), acetic acid, liquid hydrogen, liquid nitrogen, and a wide range of aggressive chemical environments. 316L contains molybdenum for enhanced pitting resistance in chloride-rich environments.

FAQ

Q1: What is the difference between sintered powder and sintered mesh filter elements?

A: Sintered powder filters and sintered mesh filters are two distinct technologies. Sintered powder filters are manufactured from metal powder, offering finer filtration precision down to 0.2μm and depth filtration throughout the entire media thickness. Sintered mesh filters are manufactured from multi-layer woven wire mesh, typically offering filtration precision down to 1-5μm and surface filtration on the outer layers. The powder sintered structure has a larger effective filtration surface area with more unobstructed flow channels, while mesh filters are generally easier to clean.

Q2: What are the advantages of a flange connection over other connection types?

A: Flange connection offers several unique advantages:

Superior sealing strength under high pressure—bolted connections prevent leakage better than threaded or O-ring seals
High-temperature tolerance—no elastomeric seals to degrade
Corrosion resistance—the all-metal interface withstands aggressive media
Vibration resistance—bolted flanges remain secure under mechanical shock
Hazardous media safety—ideal for pipelines handling flammable or toxic fluids

Flanged interfaces typically use standard flange sizes and mounting hole patterns, such as ANSI or DIN standards.

Q3: What flange standards are available?

A: We offer multiple flange configurations to match your pipeline specifications:

ANSI/ASME: Class 150, 300, 600, 900, 1500
DIN: PN6, PN10, PN16, PN25, PN40, PN64
JIS: 5K, 10K, 20K, 30K
Custom: Designed to your specific bolt pattern, facing, and dimension requirements

Major connections include universal interface for filter elements (215, 220, 222, 226, etc.), flanged joint, and other special interfaces that can be customized.

Q4: What materials are available for the sintered powder?

A: Standard materials include 304 and 316L stainless steel. For aggressive environments, we offer special alloys including Titanium, Inconel, Hastelloy, and Monel upon request. 316L contains molybdenum for enhanced pitting and crevice corrosion resistance, making it the preferred choice for chloride-rich environments.
