Why does the stainless steel screen filter bag burst?

January 26,2022

Why does the stainless steel screen bag burst? There are many reasons, such as machine and equipment, product quality, excessive pressure and other factors may lead to bag burst. Let’s talk about the knowledge of stainless steel screen filter bag.


Stainless steel filter bag refers to a bag made of stainless steel material (such as stainless steel wire or stainless steel plate). It is made and processed into a regularly arranged net, and then cut into corresponding dimensions. Commonly used materials for liquid filtration include 304 and 316 liters of materials. The main difference between them is the content of chromium and nickel. Stainless steel filter bags are used with stainless steel ring openings.


The stainless steel mesh filter bag is matched with the stainless steel ring mouth, rolled into a wavy mesh and overlapped with each other at a correct angle. Multilayer folding expansion is to arrange objects with different densities and apertures from coarse to fine, so as to change the flow direction for many times and improve the efficiency.


Technical indicators:

Material: stainless steel ring: stainless steel, galvanized, accuracy 333660 ~ 500 mesh


1. (180 * 420 mm)

2. (180 * 810 mm)

3. (105 * 230mm)

4. (105 * 380mm) and other non-standard dimensions


Advantages of stainless steel screen filter bag:

  1. High speed industrial sewing machines without silicone oil cooling will not cause silicone oil pollution.
  2. The improvement of the sewing part without high protrusion at the bag mouth resulted in side leakage without needle eye, resulting in side leakage;
  3. All labels indicating the product specification and model on the filter bag shall be removed in a convenient way to prevent the filter bag from polluting the filtrate during use.
  4. The filtering accuracy ranges from 60 mesh to 500 mesh, and the materials are divided into SUS304 or SUS316;
  5. Compared with non-woven filter bag, it is easy to clean, reusable and reduces the filtration cost.
  6. Argon arc welding technology for stainless steel and galvanized steel ring. The diameter error is only less than 0.5mm and the horizontal error is less than 0.2mm. The filter bag made of this steel ring is installed in the equipment, which can improve the tightness and reduce the possibility of side leakage


Application fields of stainless steel screen filter bag:


  1. Precision (sterilization) filtration of food and beverage, beer, wine, fruit wine, yellow rice wine, fruit juice, beverage, dairy products, edible oil, condiments and other materials.


  1. Bio-engineering and medicine: infusion of biological products, pharmaceutical water, plasma and serum, filtration of various pharmaceutical intermediates, pharmaceutical raw materials and solvents, CIP filtration, air sterilization filtration, such as air inlet ventilation of fermentation tank and yeast culture tank.


  1. Paint and ink: latex paint, paint raw materials and solvent filtration, ink and ink filtration.


  1. Other industries: purification and filtration of various liquids in fine chemical industry, petrochemical industry, electronics, textile, printing and dyeing, papermaking and other industries
