\"\"<\/figure>\n\n\n

Spiral ducting is a type of ducting used in many ventilation and HVAC systems. Unlike conventionally fabricated round ducts, spiral ducting is formed into a continuous spiral shape from a strip of material.<\/p>\n\n\n\n

For contractors, the selection of spiral pipes should be based on the diameter, thickness, design flow rate, suspension method, and aesthetic requirements of each project.<\/p>\n\n\n\n

1. What is a Spiral Duct?<\/strong><\/h2>\n\n\n\n

Spiral tubes are round in shape and are formed by twisting material into a tube.<\/p>\n\n\n\n

The distinctive structure creates a continuous spiral pattern along the tube's body.<\/p>\n\n\n\n

Sao Viet Air Ducting currently offers spiral round ducts with diameters ranging from D100\u2013D800 mm.<\/p>\n\n\n\n

3. Which type of construction is suitable?<\/strong><\/h2>\n\n\n\n

Spiral tubes can be considered in:<\/p>\n\n\n\n

    \n
  • Factory.<\/li>\n\n\n\n
  • Commercial area.<\/li>\n\n\n\n
  • Restaurant.<\/li>\n\n\n\n
  • Service space.<\/li>\n\n\n\n
  • Industrial ventilation systems.<\/li>\n\n\n\n
  • The pipeline requires an aesthetic design.<\/li>\n<\/ul>\n\n\n\n

    4. Key specifications to finalize when placing an order.<\/strong><\/h2>\n\n\n\n

    The contractor needs to provide:<\/p>\n\n\n\n

      \n
    • Diameter.<\/li>\n\n\n\n
    • Thickness.<\/li>\n\n\n\n
    • Length.<\/li>\n\n\n\n
    • Material.<\/li>\n\n\n\n
    • Type of link.<\/li>\n\n\n\n
    • Accessory.<\/li>\n\n\n\n
    • Quantity.<\/li>\n\n\n\n
    • The request is complete.<\/li>\n<\/ul>\n\n\n\n

      5. Spiral tubes are not always a replacement for rectangular tubes.<\/strong><\/h2>\n\n\n\n

      The HVAC design must remain as approved in the documentation.<\/p>\n\n\n\n

      The following considerations should be taken into account when changing from rectangular to round pipes:<\/p>\n\n\n\n

        \n
      • Equivalent cross-section.<\/li>\n\n\n\n
      • Space.<\/li>\n\n\n\n
      • Pressure loss.<\/li>\n\n\n\n
      • Accessory.<\/li>\n\n\n\n
      • Hanging rack.<\/li>\n\n\n\n
      • Connectivity.<\/li>\n\n\n\n
      • <\/li>\n<\/ul>\n\n\n\n
        \"\"<\/figure>\n\n\n\n

        Conclusion<\/strong><\/h2>\n\n\n\n

        Spiral tubing is a viable option for projects requiring circular pipelines. However, the final decision should ultimately be based on design and technical requirements.<\/p>\n\n\n\n
