Introduction to the types, models and specifications of industrial metal wire woven dense mesh

Type, model, specification, technical requirements, inspection method, inspection specification, marking and packaging of industrial metal wire woven dense mesh.

Metal wire woven dense mesh is also known as micron filter mesh, precision filter mesh, stainless steel filter mesh, stainless steel dense mesh, stainless steel mat mesh, etc.

Metal wire woven dense mesh materials: 304, 304L, 316, 316L, 310, 310S, 309S, 2205, 2507, 904L, 347, stainless steel wire, nickel wire, brass wire, tin bronze wire, nickel copper wire, titanium wire, monel wire, Hastelloy wire, Inconel wire, nickel-chromium alloy wire, titanium alloy wire, copper-nickel-iron alloy wire and other metal wire meshes.

GB/T21648-2008 Industrial Metal Wire Weaving Dense Mesh Standard is applicable to metal wire forward weaving dense mesh for gas, liquid filtration and other media separation.

GB/T21648-2008 Industrial Metal Wire Weaving Dense Mesh is applicable to metal wire forward woven dense mesh with nominal aperture ranging from 0.003 mm to 1 mm (hereinafter referred to as dense mesh).

The weaving methods of industrial metal wire woven dense mesh include plain woven dense mesh, twill woven dense mesh, bamboo flower woven dense mesh and contrast woven dense mesh.

Metal wire woven dense mesh filter is mainly used for gas, liquid filtration and other media separation.

Metal wire woven dense mesh standard: GB/T21648-2008, HB1862-93 standard production.

Wire woven dense mesh filter models: MPW, MXW, MBW;

The weft wires of the metal wire woven dense filter are closely arranged, using plain weave and twill weave methods.

The basic pore size filtration degree of the wire woven dense mesh is 347~1µm.

The metal wire woven dense mesh filter is a high-precision filter mesh carefully woven from high-quality brass, pure nickel and stainless steel wire.

GB/T21648-2008 Structural forms, models and specifications of industrial metal wire woven dense mesh

1. Structural type: plain weave and twill, among which twill is divided into full-covered twill and non-full-covered twill.

2. Model and specification: The model of metal wire mesh is indicated by "code and nominal aperture size".

A) The code for plain weave is "MPW".

B) The code for all-inclusive twill weave is "MXW'

C) The code for the non-full-cover twill weave is "MBW"

The specifications of the metal wire woven dense mesh are expressed as "basic mesh number in the warp direction × basic mesh number in the weft direction/basic diameter of the warp wire × basic diameter of the weft wire".

3. Labeling method and examples

The marking of metal wire woven dense mesh consists of model, specification and standard number.

Example 1: A plain woven dense mesh with a nominal aperture size of 55 µm and a specification of 50×280/0.16×0.09 is marked as: MPW200/50 50×280/0.16×0.09 GB/T 21648—2008

Example 2: A fully covered twill woven dense mesh with a nominal pore size of 15µm and a specification of 150×1400/0.063×0.04 is marked as: MXW630/15 150×1400/0.063×0.04 GB/T21648—2008

Example 3: A partially covered twill woven dense mesh with a nominal aperture size of 25 µm and a specification of 165×600/0.071×0.05 is marked as: MBW650/25 165×600/0.071×0.05 GB/T21648-2008

1. The wire material, surface quality and wire diameter deviation shall comply with the requirements of JB/T7860.

2. The mechanical properties of the metal wire and the minimum weight of a single piece shall comply with the requirements agreed upon by both the supplier and the buyer.

3. The specifications of the metal wire woven dense mesh, the mesh size and deviation between the warp wires, and the weft wire density should comply with the provisions in the table. Specifications not listed in the table can be provided upon agreement between the supply and demand parties.

4. The number of large mesh holes between warp threads shall not exceed 3% of the total number of warp threads.

5. The width of the metal wire woven dense mesh is 800mm, 1000mm, 1250mm, 2m, and the width deviation is +20mm. It can also be agreed upon by both parties.

GB/T21648-2008 Inspection rules for industrial metal wire woven dense mesh

1. The dense mesh can only be shipped after being inspected and qualified by the manufacturer's quality inspection department.

2. The dense mesh should be submitted for inspection in rolls. If a roll contains several sections of mesh, each section must be inspected.

3. The purchaser may inspect the dense mesh according to the following contents to determine whether it meets the various indicators specified in this standard.

a. Type of weaving, b. Quality of weaving. c. Warp and weft density. d. Width, length and quantity of mesh. e. Diameter of metal wires. f. Chemical composition.
