What is a Sintered Wire Mesh? A sintered wire mesh is a filtering material constructed through pressing and sintering single or several layers of woven wire mesh panels.
The process forms strong, permanent bonds through heat and pressure, giving it superior and comprehensive filtration properties compared to standard woven wire mesh filter.
A sintered wire mesh can have between 2 and 7 layers or even more dependent on the customer’s needs and specifications.
Initially, you uniformly roller flattened a single layer of wire mesh to create a wire cross to ensure efficient contact. If you want to create a multilayered mesh, then proceed and pile the components appropriately, ensuring that you laminate the fine filtering mesh with coarser protective layers. Using a unique fixture, laminate the single or multiple mesh layers through subjecting it to high temperature and mechanical pressure. Press in chambers filled with proprietary inset gas and raise the temperature to reach the sintering (diffusion bonding) levels. Cool the sintered wire mesh under controlled conditions to achieve the desired level of rigidity. After that, you can follow and work the material as expected: weld, cut, pleat, roll into diverse shapes, etc. What is the Importance of Sintering a Wire Mesh? Pressing and sintering metal wire mesh creates a filtration material with superior filtration properties compared to standard woven wire mesh. Sintering creates a secure and stable wire mesh that is suitable for use under high-pressure conditions. You can use a sintered wire mesh to construct diverse kinds of filter elements such as cartridges, cylinders, discs, and candles because they have excellent mechanical strength, very stable, and durable. What is the Difference Between Sheet Sintering and Coil Sintering? Both sheet sintering and coil sintering are done to permanently bond the wire mesh intersections through heat, pressure, time, and atmosphere. However, you can construct either single of the multilayered sintered sheet while you can only build a single layer of the sintered coil. Whereas sheet sinters are ideal for filtration in high-pressure applications, coil sinters are suitable for applications that cannot tolerate loose wires and deep drawing. What Types of Applications use a Sintered Wire Mesh? Sintered wire mesh is usually used in the construction of filtration and purification devices. You can use sintered wire mesh filters in diverse industries to filter fluids. Some of the common industries that employ the use of sintered wire mesh include: ·Production of oil and gas filtration: You can use sintered mesh to construct sand control screens, flame retardant filters, and backwash filters ·Nuclear and energy: You can use it to manufacture coolant process filters, fluid bed filters,and discharge filters. ·Pharmaceutical industry: You can use it in the manufacture of scrubbing and drying units, drug purification, and medical filter plates. ·Petrochemical and refining industries: Sintered wire mesh are useful in the filtration of hot gases and corrosive liquids as well as recovery of catalysts ·Aerospace: You can use the material to construct hydraulic filters, Precise lubricating oil filters, and noise abatements ·Polymer filtration: It is fundamental in the manufacture of synthetic fibers, spin packs, and processing films. ·Food and beverage: You can use sintered wire mesh filters for filtration of flour, milk powder, impurities, water, and disposal sewage.

Yes, you can clean sintered wire mesh filters using diverse cleaning methods. The most commonly used methods are physical and chemical. Physical methods involve using an ultrasonic cleaning machine, backflushing with cleaning gas or cleaning liquid recoil. You can also clean your sintered wire mesh by chemical means, which involve diluting acid or alkali, surfactants, oxidizers, and any other suitable agent. The choice of a particular cleaning technique depends on the status of contamination, physiochemical properties of the construction material, and the contaminants’ chemical properties. Furthermore, you can use a combination of these methods interchangeably to achieve the desired level of product regeneration. Why should you choose a Sintered Wire Mesh over Non-woven Fibers? The main difference between sintered woven wire mesh and sintered non-woven fiber mesh comes in the products’ construction phase before sintering. Sintered Woven Mesh You can manufacture this product through sintering together layers of woven mesh. It has the following key advantages. ·You can fabricate them using a diverse array of construction materials, given that you will not need to weld the parts together. ·They are a perfect choice for devices with irregular shapes since you don’t have to weld them together. ·Producing sintered woven wire mesh is cheaper, easier, and faster. ·You can achieve filtration of the required sharp cut-point since it can provide the precise pore sizes needed. ·The end products will contain particles of a specific size. ·Produces lower pressure drop compared to sintered non-woven mesh ·More flexible and affordable. Sintered Non-woven Mesh These products are less flexible but more robust than woven mesh because the raw material is built through welding metal strands together. ·They are slightly expensive and only suitable for the construction of components with rigid designs. ·Very difficult to fabricate and consumes more time compared to woven mesh ·Need precise fabrication ·You can easily compromise the ability of the sintered non-woven mesh to filter contaminants when handled excessively. ·Possess inconsistent pore sizes because the knitting process lacks a specific defined position. ·It is more difficult to clean than sintered woven wire mesh because strand welding may produce variable pore sizes that capture particulate contaminants. Can you Construct Multiple Layers of Sintered Wire Mesh? Yes, you can construct multilayered sintered wire mesh. The majority of the applications are better suited using multilayered sintered wire mesh instead of a single layer sintered wire mesh. A multilayered sintered wire mesh can achieve the desired micron rated filtration while still maintaining superior mechanical strength required of demanding applications. Besides, a multilayered wire mesh is easier to clean since it can withstand the high backwash pressure. It also has superior structural integrity and easily maintains the appropriate filter rating under intense filtration pressure. What are the Properties of Sintered Wire Mesh with Different Layers? Sintered wire mesh can have either a single or multiple layers. In the case of multilayered sintered wire mesh, the number of layers can significantly influence its properties. Below are some of the characteristics of different types of layered sintered wire mesh.
Sintered wire mesh filters · Single Layered Sintered Wire Mesh This product has a permanent filter rating, pore size, and geometry due to diffusion bonding effectiveness. You can consider the single-layered wire mesh for constructing low-cost filters fabricated either as cylinders, discs, rings, etc. The construction of the product does not require any sealing technique. · Double and Triple-layered Sintered Wire Mesh The double-layer has a filtration layer enclosed between protection layers either on the outside, inside, or both sides. It is suitable for constructing sintered discs, candle filters, or pleated cylinder filters. · Five Layered Sintered Wire Mesh The fine filtration wire mesh layer is sandwiched between two coarser protective layers and then sintered together with two support layers for enhanced stability. The two protective layers protecting the fine mesh filtration layer is enclosed between the two supportive layers. This type of sintered wire mesh has excellent mechanical strength and resistance to pressure. It finds usefulness in different industries and applications with demanding operating conditions. · Six Layered Sintered Wire Mesh This product resembles a five-layered sintered wire mesh with an additional drainage layer. It is preferred for enhancing filtration capacity quantities. What Factors should you Consider when Constructing a Filter Element using a Sintered Wire Mesh? The design specifications of your filter element must meet the desired level filtration and withstand your system’s operating conditions. The following are some of the basic parameters you should consider while designing your sintered wire mesh filter elements. · Pore Sizing Your filter’s pore size rating dictates the size of particles your filter will be able to retain. A filter element rated 5 microns’ absolute’ will retain all particles with a diameter of 5 microns and below. In contrast, when the same filter is rated ‘nominal,’ then your filter will allow a high percentage bypass of the particles measuring 5 microns. · Pressure Drop Pressure drop is the loss of pressure on the filter outlet due to slowing down the process fluid as it goes through the filter. Determine the allowance of your system pressure drop during the filter designing so as not to slow down your production process. · Operating Temperature You should determine the minimum and maximum allowable temperatures that your process application operates on. It ensures that the metal alloys you choose can tolerate the temperature extremes on both ends to avoid element disintegration. · Strength Though all sintered woven wire mesh filers possess excellent tensile and mechanical strength, you still need to determine your system requirements. Fabricating sintered wire mesh filter elements that meet the system specifications goes a long way to ensure your filter elements’ effectiveness and durability. · Others In addition to the above considerations, you also need to have a more profound mastery of your process application to ensure that you fabricate the most suitable elements. Accompanying your order alongside the following information will deliver you a product that is accustomed to your system’s unique needs. ·The type of your system application ·The nature, kind, and characteristics of the process fluid ·The features of the contaminants ·Any corrosive problems in your operating environment ·The element size, design, and shape required ·The working flow rate, pressure, and temperatures ·The mounting, installation methods How long can a Sintered Wire Mesh Filter last? A sintered wire mesh’s service life significantly varies to grade, operating conditions, quality, the material of construction, among other factors. When you schedule your filter regeneration right, then you can use a sintered wire mesh filter element for up to five or more years before the need for replacement. However, the service life of your sintered wire mesh layer can significantly reduce to only a few months. The reduction is faster when you fail to select an appropriate material for constructing your wire mesh under extremely corrosive conditions.
