Sintered Metal Powder Filter Element
Sintered Metal Powder Filter Element
LiandaFiltration sintered metal powder filter elements adopt powder metallurgy technology to sinter high-purity stainless steel or Inconel alloy powder at high temperature to form a stable porous network structure, which can be used for a long time in a high-temperature filtration environment. Combined with the design concept of High Temperature Sintered Metal Filter Elements, this filter element has excellent mechanical strength, chemical corrosion resistance and washability, and is particularly suitable for particle separation and precision filtration needs under harsh working conditions.

Product Features and Benefits
High Temperature Stabilization
High Temperature Sintered Metal Filter Elements are sintered from Inconel alloys or 316L powders to withstand environments up to 550°C for steam and high temperature gas filtration.
Rugged, corrosion-resistant construction
The sintered metal filter layer is binder-free and chemically stable to withstand strong acids, bases and organic solvents. In particular, Inconel Sintered Metal Filter Elements excel in high-temperature corrosive environments.
High throughput and low pressure drop
Uniform interconnected pore network ensures a large effective filtration area with lower fluid resistance than polymer cartridges of the same precision, increasing system capacity.
Reversible cleaning and regeneration
Supports high-pressure water jet rinsing, ultrasonic, or chemical cleaning for consistent performance over multiple cycles, reducing long-term replacement costs.
Multifunctional compatible
It can be used as Sintered Metal Filter Cartridge for Industrial Filtration for regular liquid filtration, and also can be used for diffusion and homogenization in gas distribution, spraying, degassing and other processes.
Product application industry
Petrochemicals: catalyst protection, crude oil desalting and dewaxing, styrene polymerization reaction gas filtration.
Power and metallurgy: boiler feed water deoxygenation, high-temperature dust removal, exhaust gas pretreatment.

How do we produce your sintered filters and perform quality control?

raw material
LianDaFiltration always insists on selecting uniform raw material powder to produce each sintered filter with large pore size, high tensile strength and temperature stability in the future.

powder filling
The isostatic pressing filling process is used to achieve uniform powder density and eliminate pore defects.

High sinterability
High temperature sintering under vacuum argon protection improves the tightness of micropore connection and enhances pressure resistance.

CNC machining
Through CNC turning and grinding, the filter element geometric accuracy is maintained at ±0.02 mm to meet high-precision filtration requirements.

weld
The laser welded joints are delicate and smooth, with no risk of leakage, which improves the sealing reliability of the filter.

Dimensions
LianDaFiltrationCheck all dimensions of the sintered filter using pressure gauges and high-efficiency dimension monitoring equipment.

filter test
Micropore interception rate evaluation and pressure burst test are used to ensure that each filter element passes the quality inspection in one go.

Product packaging
LianDaFiltration All sintered filter products and accessories are packed in accordance with international standard safety procedures to meet the standards,
Through the above eight processes and strict testing, LiandaFiltration provides you with stable and reliable sintered filter products.
FAQ
If the operating temperature is > 350 ℃ or the medium contains corrosive sulfides, Inconel Sintered Metal Filter Elements are recommended; in conventional high-temperature steam and acid-base environments, 316L is usually sufficient.
Depending on the increase in differential pressure (ΔP) and changes in production, it is generally recommended to clean the system when the differential pressure exceeds the initial value by 0.2 bar; under stable operating conditions, deep cleaning should be performed every 6-12 months.
Both 366L and Inconel materials comply with USP Class VI and FDA-related metal material safety regulations; after surface electrochemical polishing, they can meet GMP, 3-A and other sanitary requirements.
LiandaFiltration supports full customization of outer diameter, length, filtration accuracy and porosity, and provides process parameter simulation and sample verification.
