Versatile Stainless Steel Fiber Sintered Felt Filter Material

The versatile stainless steel fiber sintered felt filter material is an efficient, high temperature resistant and corrosion resistant filter material. This material is made by a special manufacturing process in which stainless steel fibers are ground, laminated, and then diffused and bonded (i.e. sintered) at high temperatures to form a porous structure with high porosity and uniform pore size distribution.

Production process

The production process of the versatile stainless steel fiber sintered felt filter material begins with the selection of stainless steel fibers of suitable diameter. These fibers are usually between a few microns and tens of microns in diameter. First, these fibers are dispersed and then evenly laid into a network structure through special equipment. Next, the laid fiber web is placed in a high temperature furnace for sintering. In this process, the fibers are partially melted under the action of high temperature, and welding points are formed between adjacent fibers, thus forming a three-dimensional network structure with high strength and stability. The sintering process needs to be carried out in a protective atmosphere (such as argon or nitrogen) to prevent the fiber from oxidizing.

Physical and chemical properties

1. High porosity

The porosity of stainless steel fiber sintered felt can be as high as 85% to 90%, which makes it highly permeable and low flow resistance, making it suitable for rapid filtration of fluids.

2. Uniform pore size distribution

The material is able to provide a very uniform pore size distribution, which is achieved by adjusting the fiber diameter and sintering conditions. The uniform pore size ensures efficient particle interception and a low particle release rate.

3. High temperature resistance

Due to the use of high temperature resistant materials such as stainless steel, stainless steel fiber sintered felt can work stably at temperatures up to 1000 °C, suitable for many high temperature environments.

4. Corrosion resistance

The stainless steel material gives the sintered felt good corrosion resistance, allowing it to cope with most acids, alkalis and organic solvents.

5. High mechanical strength

The weld joints formed during the sintering process increase the mechanical strength of the material, enabling it to withstand higher pressure and mechanical impact.

6. Washable and regenerative

The porous structure of the sintered felt allows for the removal of trapped particles by backwashing or chemical cleaning, enabling the regeneration of the filter.

Parameters

4. Oil and gas industry

In the process of oil production and natural gas refining, it is often necessary to deal with high temperature and high pressure conditions. The versatile stainless steel fiber sintered felt filter material is an ideal choice for these occasions due to its excellent temperature and pressure resistance.

5. Aerospace

In the aerospace field, the versatile stainless steel fiber sintered felt filter material can be used for the filtration of fuel and lubricating oil, ensuring high-precision filtration while meeting the requirements of extreme environments.

Use precautions

1. Correct selection of specifications

Choose the appropriate fiber diameter and felt thickness according to the filtration accuracy requirements of the specific application. Different applications may require different ranges of micron-level filtration accuracy.

2. Installation and maintenance

When installing, ensure that the surface of the felt is evenly stressed to avoid damage or leakage of the filter material caused by improper installation. Regular maintenance and cleaning can significantly extend the service life.

3. Chemical compatibility

When selecting a material, the chemical properties of the filter medium must be taken into account to ensure the chemical compatibility of the selected material with the processing fluid.

4. Temperature Effect

Although stainless steel fiber sintered felt can work at high temperatures, excessive temperatures may affect its structural stability and filtration efficiency. When using, operate according to the temperature range recommended by the manufacturer.
