  1. Uses<\/strong><\/li>\n<\/ol>\n
      \n
    • Change the direction of the circular duct 90\u00b0<\/strong> in ventilation, air conditioning, fire protection smoke extraction systems.<\/li>\n
    • Helps to arrange the system flexibly, suitable for the construction space while still ensuring air flow.<\/li>\n
    • Minimizes pressure loss when changing direction thanks to rounded design, which can be supplemented turning vanes<\/strong> inside.<\/li>\n<\/ul>\n
        \n
      1. Material<\/strong><\/li>\n<\/ol>\n
          \n
        • Galvanized steel Z080<\/strong> (Hoa Sen \/ Hoa Phat) standard, anti-corrosion.<\/li>\n
        • Material thickness: 0.48mm \u2013 1.0mm<\/strong> depending on diameter and wind pressure.<\/li>\n
        • Options: Stainless steel 304\/201<\/strong> or powder coated steel for special environments (humid, highly corrosive).<\/li>\n<\/ul>\n
            \n
          1. Specifications \u2013 Dimensions<\/strong><\/li>\n<\/ol>\n
              \n
            • Diameter (\u00d8): 100 \u2013 1250 mm.<\/li>\n
            • Elbow angle: 90\u00b0<\/strong> (can be machined 45\u00b0, 60\u00b0 upon request).<\/li>\n
            • Radius of bend (R): R = 1.0D to 1.5D for optimal flow.<\/li>\n
            • Connector: female end<\/strong> or male end<\/strong>, with stiffener.<\/li>\n<\/ul>\n
                \n
              1. Processing method<\/strong><\/li>\n<\/ol>\n
                  \n
                • Processed by bending machine and round seam welding, ensuring airtightness.<\/li>\n
                • Curved sections are assembled from multiple pipe segments to achieve high accuracy and roundness.<\/li>\n
                • Joints treated with airtight glue or leak-proof tape.<\/li>\n<\/ul>\n
                    \n
                  1. Application<\/strong><\/li>\n<\/ol>\n
                      \n
                    • System HVAC<\/strong>: cold air supply, fresh air, return air.<\/li>\n
                    • System smoke extraction \u2013 fire protection<\/strong> in factories, high-rise buildings.<\/li>\n
                    • Ventilation systems for basements, garages, industrial zones.<\/li>\n<\/ul>\n
                        \n
                      1. Advantage<\/strong><\/li>\n<\/ol>\n
                          \n
                        • Tight, secure<\/strong>, anti-leakage.<\/li>\n
                        • Optimize air flow<\/strong> With reasonable bend radius, reduce pressure loss.<\/li>\n
                        • Easy to install<\/strong> with flexible connector types.<\/li>\n
                        • Custom processing<\/strong> size, elbow angle, bend radius.<\/li>\n<\/ul>","protected":false},"excerpt":{"rendered":"
