1.A transverse flanging system used to fix one length of duct to the adjacent length of duct. 2.A duct flange, or duct frame, is used in the air conditioning and ventilation industry to bolt lengths of ducting to each other. 3.Material: galvanized steel or stainless steel 4.Flange size: 20/25/30/35/40mm 5.Flange thickness: 0.7-1.2mm 6.Corner size: 20/25/30/35/40mm 7.Corner thickness: 1.8-4.0mm Special size upon your request. Duct corners are an important part of any heating, ventilation and air conditioning (HVAC) system. It plays a vital role in directing airflow and maintaining efficient performance.Here are a few advantages of using duct corners in HVAC systems:Improved Airflow Efficiency: The main purpose of duct corners is to change the direction of airflow smoothly and efficiently. By strategically positioning duct corners, you can ensure airflow moves seamlessly around corners and through different parts of the system, minimizing drag and pressure drop. This increases overall system efficiency and better distributes conditioned air throughout the building.Space Optimization: Space constraints can be a challenge in many HVAC installations. Pipe corners allow for more flexibility in placing pipes as they can go around obstacles or tight spaces. This not only optimizes the use of available space, but also allows for a more compact and simplified HVAC design. Reduced Energy Loss: Properly installed duct corners help minimize energy loss in the HVAC system. By reducing bends and turns in the airflow path, duct corners minimize friction and turbulence that can lead to energy loss through air leaks or inefficient air distribution. This helps maintain desired temperature and airflow levels while reducing energy consumption.Improved System Performance: Efficient airflow management is critical to maintaining optimal HVAC system performance. By using duct corners, you can ensure that the air is distributed evenly and efficiently to all areas of the building. This helps eliminate hot or cold spots and ensures a comfortable indoor environment for occupants.Noise reduction: HVAC systems generate noise due to the movement of air within the ductwork. Use of duct corners optimizes the airflow path and minimizes turbulent air movement, which helps reduce noise transmission.This results in a quieter system and a more pleasant indoor environment. In conclusion, duct corners are an important part of an HVAC system and offer several advantages.From improving airflow efficiency and optimizing space utilization to reducing energy loss and noise transmission, well-designed and properly installed duct corners can significantly improve the performance and comfort of any building.
