The high-performance steel disc is a wedge-shaped filtration device that automatically filters the materials by applying differential pressure and controlled duration.

The mesh size of the disc plays an influential role in the filtration of impurities upon arrival of inlet pressure. It creates a pressure difference that allows the efficient flow of materials through the disc.

The significant drop in pressure turns on the backwash function to remove impurities. The continuous collision of particles forms a compact mass of residues for quick removal.

Hence, the trapped particles are removed after collecting them from the surface of the steel disc.

Figure 4 Industrial Applications Of Steel Disc

Figure 4 Industrial Applications Of Steel Disc

Although 304 and 316 stainless steel discs are reliable, there is a fundamental difference in the composition of these two materials.

316 stainless steel elements include 10% nickel, 16% chromium, and 2% molybdenum. On the other hand, 304 stainless steel elements include 18% chromium and 8% nickel.

The addition of molybdenum offers excellent resistance against corrosion in alkali and acidic environments. Chromium adds high tensile strength to withstand high pressure and temperature.

It is suitable for working in high saline and corrosive industrial environments because it shows non-reactive behaviour during the filtration process.

However, selecting 304 or 316 stainless steel material depends on industrial applications.

The steel disc is suitable for filtration, extraction, and separation of fluids and gases under critical working conditions and is ideal for applications under extreme hot and cold conditions.

Yes, it is possible to clean a steel disc using the appropriate method. Always find a suitable detergent that does not react with the material of the filtration device.

Usually, backwashing is the most reliable method for cleaning steel discs and filters. It involves the application of pressurized water in reversed direction.

Hence, the water flows from output to input and all the contaminants. It ensures the complete removal of dirt particles and makes them ready for future applications.

However, determine the pressure bearing strength of the steel disc before applying pressure in the reverse direction.


The accurately positioned weaving design helps to maintain a steady flow of materials. It helps to capture dirt, dust, and contaminants during the filtration process without affecting the flow rate.

Following are the common weaving types for a steel disc:

  • Dutch weave

We are ISO 9001:2015 certified for the manufacturing of steel disc products. We are fully dedicated to using high-quality materials to ensure the performance and working of steel disc elements.

Our experts perform two quality tests to check the performance. It including:

  • Bubble point hydraulic filter test: This test is performed to evaluate the standardized manufacturing procedures. Hence, it determines the porosity level of steel disc elements.
  • Corrosion-resistant test/Salt spray method: This test is performed to evaluate the durability of steel disc elements. This test determines the excellent performance of stainless steel products under high temperatures, pressure, and corrosive environments.

The bubble point hydraulic filter test method is used as a standard quality test to determine the integrity of stainless steel mesh elements. This test also evaluates the integrity of our standardized manufacturing procedures.

This test involves attaching a clean and dry compressed airline via a seal at the steel disc. After this, pressure increases slowly until the first steady stream of bubbles comes on the surface.

It determines the pore size of the steel disc. A manometer measures the degree of pressure coming out from the inlet valve. We perform this test to identify any defect during the filtration of gases and liquids.

Figure 9 Bubble Point Hydraulic Test Apparatus

Figure 9 Bubble Point Hydraulic Test Apparatus

A corrosion-resistant test is used to evaluate the performance and durability of steel discs for the filtration processes. Primarily, a salt spray machine is used to check the corrosion resistance of materials.

The steel disc is exposed to a high-saline corrosive environment (5% NaCl solution) for approximately 24 to 48 hours under controlled temperature and pressure conditions.

Usually, white and rust spots appear on the surface of low-quality steel products. The steel disc elements are observed over a prolonged duration after specific intervals.

The high-quality materials of steel discs make them resistant to alkali and acidic conditions in industrial units.

The steel disc is manufactured through high sintering and metallurgy methods. The pore size is accurately adjusted by filling the mould with stainless steel material and sintering.

Then, it is moved to high-temperature furnaces to diffuse the particles quickly. The diffusion process here increases the mechanical strength of the particles to achieve the desired porosity level.

The powdered steel disc particles are then cooled at room temperature. The temperature is controlled accurately during the sintering and metallurgy procedures to maintain the porosity level.

The metallurgy process helps keep a steel disc’s physical and chemical properties.

Figure 12 Manufacturing Process OF Steel Disc

Figure 12 Manufacturing Process OF Steel Disc

The steel disc elements follow three-particle capturing mechanisms:

  • Diffusion interception on top of particles
  • Diffusion interception in the middle of particles
  • Inertial impaction or interception at the bottom

The random bouncing of particles in liquid or gases helps the particles to come out of the surface. These particles then pass through pores. At this stage, the steel disc directly captures particles.

Then, inertial impaction maintains particles’ velocity, mass, and momentum while moving out of the surface. It eliminates particles in a straight line. However, the captured particles are removed easily by washing steel discs with detergents.

The average price of steel disc elements depends on their quality. Its price ranges from $15 to $50. However, we guarantee our products’ performance, durability, and reliability.

The variable price ranges involve the difference in materials, porosity level, diameter, thickness, size, and geometry. All these factors determine its flow rate.
