23mm Mild Steel
23mm Mild Steel
Mild Steel Ducting is designed for industrial applications such as ventilation, vacuum, and pneumatic conveying. It is available in thicknesses ranging from 2-5 mm and can be made from mild, corten, or stainless steel. The maximum operating temperature is +80°C.
- Material: Mild steel with a thickness of 2-3 mm.
- Connections: Options include flanged, clipped edge, and straight edge.
- Steel Quality: Cold rolled steel sheet in 1312.
- Materials available: Corten steel and stainless steel.
- Custom thicknesses available upon request.
- Painted in RAL 7032.
- Priming: 50 μ with 70% zinc content.
An air volume chart is provided to help select the correct duct size based on air volume requirements. For example, a 100 mm duct conveys 622 m3/h at 22 m/s, optimal for wood chips and sawdust flow between 18 and 25 m/s.
- Various duct sizes and weights are listed for lengths of 2000 mm, 1000 mm, and 500 mm.
- Item numbers and weights are provided for each size and length.
- Use FSFE or FSDB clips for ducts and fittings with clipped edges.
- For flanged ducts, use bolt, nut, and flange gasket FSAZ.
Examples include ordering ducts with specific dimensions and finishes, such as "Duct W MS 2mm 450FB L=0.5m RAL 7032".
- Flanges and gaskets available in various sizes and materials, including galvanized and mild steel.
- Bends are made from steel quality SS1312 with a maximum operating temperature of 80°C.
1. Use FSFE or FSDB clips for duct and fittings assembly with clipped edges.
2. Dimensions Ø 100-300 are pressed execution, then segments are built.
3. Radius (R) is calculated as 1.5 times the diameter (d).
1. Mild steel bends available in 2mm and 3mm thicknesses.
2. Steel quality is SS1312 with a base and top coat of RAL 7032 grey, 50 microns.
3. Maximum operating temperature for the finish is 80°C.
4. Loose flanges are of type FSSA, and for assembly with flanges, use bolt, nut, and flange gasket FSAZ.
1. Bend Seg MS 2mm 450FB 90Deg R=1.5 RAL 7032.
2. Bend Seg MS 3mm 800FB 90Deg R=1.5 RAL 7032.
1. The catalogue includes a variety of mild steel products with different dimensions and weights.
2. Products are designed for quick changes between two streams and are ideal for conveying dust particulate.
3. Diverters meet EU’s machinery directive (98/37/EC) and are available in manual and automatic versions.
1. Diverters should be connected to clean and dry compressed air.
2. Normal working pressure is 0.6 MPa (6 bar), with a maximum pressure of 1.0 MPa (10 bar).
3. Temperature range for operation is 80°C (dry air 20°C).
The document provides a detailed product catalogue for mild steel duct systems with thicknesses ranging from 2-3 mm. It includes specifications for various duct sizes, identified by diameter (Ø A mm), item numbers (RGSL and RGBL), length (L mm), dimensions (X and Y mm), damper blade thickness, and weight for both RGSL and RGBL items.
