SP, DP, HR, HP gas-liquid filter, gas-liquid filter, wire mesh demister types, specifications and parameters introduction
Gas-liquid filter net is also known as gas-liquid filter net, gas-liquid net, foam breaking net, filter net, knitting net, knitted metal net, double-layer stainless steel wire net, etc. It is actually a wire mesh woven by improving the traditional sweater needle knitting method. The wire used for weaving is generally round wire of φ0.08~φ0.50mm or pressed flat wire. The wire diameter ≤φ0.30mm can be knitted in multiple strands, and the form of multiple strands can also be knitted by metal wire and fiber wire.
Detailed introduction of gas-liquid filter
1. Wire diameter range: 0.10mm-0.55mm (commonly used wire diameter is: 0.20mm-0.25mm) In addition, multiple strands of wire are twisted together for weaving.
2. Hole size: from (2×3mm) to (4×5mm) and then to (12×6mm). In addition, the hole size can be fine-tuned according to customer requirements. The hole form is a cross arrangement of large holes and small holes (the size of the holes in the length direction is the same, but the width is different)
3. Surface condition of gas-liquid filter: flat mesh surface and corrugated mesh surface (corrugated width and depth have different specifications)
4. The width range of the gas-liquid filter is: 40mm, 80mm, 100mm, 150mm, 200mm, 300mm, 400, 500mm, 600mm, 1000mm 1524mm, etc.
5. The main materials of gas-liquid filter: stainless steel wire AISI201, 202, 301, 302, 304, 304L, 321, 316, 316L, pure nickel wire, pure titanium wire, monel, galvanized wire, modified drawn wire, stainless steel wire and cotton thread or plastic, PP, PC, PE, PVC, PTFE.
HG/T21618-1998 wire mesh demister gas-liquid filter specifications include: SP, DP, HR, HP type four standard specifications. Wire mesh demister gas-liquid filter specifications include: HG5-1404, HG5-1405, HG5-1406, standard number is Shanghai Q/SG12-1-79. The standard specifies three types of gas-liquid filters, namely standard type, high efficiency type and high penetration type.
For various non-standard woven meshes provided by users, such as multi-strand woven meshes, sealing gaskets of various shapes, sleeves, etc., we can customize them according to the mesh size and wire diameter.
Screen Material:
Metal wire: various stainless steel wire, galvanized iron wire, copper wire, nickel wire, titanium wire, alloy wire
Non-metallic wire: nylon wire, polyethylene wire, polypropylene wire, F46 wire, glass fiber wire
Gas-liquid filter application areas: production of wire mesh demister filter pads; filter screens for gas-liquid separation, gas-water separation, oil-water separation and other devices; various filter elements on engines of automobiles, tractors, etc.; sealing, shock absorption (shock absorbers), silencers and exhaust purification components in automotive parts; shielding devices for electronic and electrical products to prevent electromagnetic interference.
The diameter specification range of gas-liquid filter mesh is: 0.08-0.3mm flat wire or round wire. Single-strand weaving, multi-strand weaving, metal wire and non-metal wire (various fibers) weaving, etc., can be pressed and rolled into various styles and specifications of corrugated shapes on the wire mesh according to needs, such as "herringbone" pattern. Gas-liquid filter mesh is the raw material for producing defoamers and can be used directly as filler.
There are four standard specifications of steam-liquid filters for wire mesh demisters: SP, DP, HR, and HP.
The specifications of steam-liquid filters for wire mesh demisters are: HG5-1404, HG5-1405, HG5-1406, and the standard number is Shanghai Q/SG12-1-79.
It is widely used in oil refining, petrochemical, chemical industry, salt industry, electric power industry, sugar industry, paper industry, electronics industry, environmental protection and some other industrial places. Other application environments include: vacuum tower, absorption tower, separation tank, gas separation container, compression absorption tower, evaporator, washing tower, distillation tower, recovery container, dust collection device, anti-magnetic interference products, shock absorber, etc.
