Stainless Steel Sintered Wire Mesh Filter

Sintered wire mesh filter is a type of porous filter media that is produced by sintering multiple layers of woven wire mesh. Sintering is a manufacturing process that involves bonding the mesh layers together by applying heat and pressure, without using any additional adhesives or binders. This process creates a sturdy and durable material with uniform pore sizes and excellent filtration properties.

What is the main material of sintered wire mesh?

The main material used for sintered mesh is typically stainless steel, e.g. 316L, 316, 304, 304L. Stainless steel is chosen for its excellent mechanical properties, corrosion resistance, and high temperature resistance, making it suitable for a wide range of industrial applications. Other materials such as bronze, nickel alloys, and titanium can also be used depending on specific requirements. However, stainless steel is the most commonly used material for sintered mesh due to its durability, chemical stability, and availability in different grades to suit various operating conditions.

Types of Sintered Mesh Filter

Single-layer Sintered Mesh: This type consists of a single layer of sintered wire mesh. It offers basic filtration capabilities and is commonly used for applications that require coarse filtration.

Multi-layer Sintered Mesh: Multi-layer sintered mesh consists of several layers of sintered wire mesh stacked on top of each other. The layers are progressively finer, with the coarser layers acting as support and the finer layers providing efficient filtration. This type offers enhanced filtration performance and is suitable for applications requiring fine filtration.

Sintered mesh can have multiple layers, typically ranging from 2 to 5 layers. The number of layers affects the filtration efficiency and the overall strength of the mesh.

Filter Fineness / Filter Rating

Multi-layer sintered mesh offers finer filtration rates due to the presence of progressively finer mesh layers. The filtration rate for multi-layer sintered mesh can range from sub-micron levels (less than 1 μm) up to several hundred microns. Multi-layer sintered mesh is used for applications that demand precise and efficient fine particle filtration.

Reinforcing Layer of Sintered Mesh

In sintered mesh, there are generally two main types of reinforcing layers:

  • Crimped Wire Mesh Reinforcing Layer: An additional layer of crimped woven wire mesh with larger diameters is incorporated into the sintered mesh structure. The crimped wire mesh layer is placed on one or both sides of the sintered mesh to provide additional mechanical strength and stability, improving its resistance to pressure and impact.
  • Perforated Metal Reinforcing Layer: In this type, a perforated plate made of metal, often stainless steel, is added to one or both sides of the sintered mesh. The perforated plate provides additional support and strength to the sintered mesh, making it more robust and durable. This reinforcement is commonly used in applications where the sintered mesh needs to withstand high pressures, mechanical stress, or to prevent deformation during use.
