Sintered stainless steel filter plate
Sintered stainless steel filter plate
The powder metallurgy process is used to sinter high-quality 316L stainless steel powder at high temperature to form a uniformly interconnected porous structure. With the advantages of high-precision metal filter plates, this filter plate has the characteristics of high temperature resistance, corrosion resistance, and can be repeatedly cleaned and regenerated, which is very suitable for the needs of industrial-grade metal sintered filter plates under harsh working conditions.

Product Features and Benefits
High-precision filtration
The sintered pore size distribution is uniform, which can achieve nano-level filtration, excellent removal of fine particles and microorganisms, and ensure the quality of downstream equipment and products. High mechanical strength, very suitable for high pressure difference and high flow rate
High temperature and corrosion resistance
The 316L substrate maintains mechanical strength below 550 ℃, suitable for high temperature catalyst recovery, steam purification and other high temperature resistant metal filter plates, corrosion resistance
Can be repeatedly cleaned and regenerated
Unlike traditional filter paper or polymer filter elements, metal sintered filter plates support high-pressure water gun flushing, ultrasonic cleaning or chemical cleaning, and the service life can reach several years.
Solid and stable structure
The whole is formed in one piece, without adhesive residue, not easy to crack and deform, suitable for multiple cycles, reducing replacement costs.

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,

FAQ
Stainless steel filter plate is one of the plate filters made of sintered stainless steel or stainless steel wire mesh. The size and pore size of the filter can be customized according to the flow, temperature and pressure requirements.
Please match the filter plate based on the particle size of the media, the maximum flow rate and the allowable pressure difference, combined with the specific surface area and porosity of the filter plate. LiandaFiltration can provide process simulation and selection recommendations.
High-temperature gas or steam purging can be performed below 500°C, combined with chemical cleaning to achieve efficient regeneration.
Under normal working conditions (without strong acid or alkali shock), it can be used stably for 3-5 years; the cleaning frequency and medium cleanliness determine the service life.
Support non-standard customization services in various sizes, shapes and thicknesses to meet the needs of different equipment and processes.
