Guida all'acquisto

In base ai feedback reali degli utenti, forniamo i seguenti suggerimenti:

  • In the actual procurement process of rectangular ducts, it is recommended to prioritize confirming the cross-sectional dimensions and wall thickness based on the air volume requirements of the ventilation system. Conventional specifications such as 1200mm × 600mm or 800mm × 400mm should match the design parameters.
  • For different scenarios such as commercial buildings and industrial plants, the material selection of rectangular ducts needs to be distinguished. Galvanized steel plates are suitable for general environments, while stainless steel is more suitable for high humidity or corrosive environments.
  • When selecting suppliers, priority should be given to product matching, business qualifications, enterprise activity, industry performance, and enterprises with industry data support or platform statistical information to ensure supply stability.
  • In high-rise buildings or long-distance air supply systems, attention should be paid to the connection method and pressure performance of rectangular ducts, as flange connections or plug-in structures have a direct impact on sealing.

Circular air ducts have a small wet circumference and low resistance of 15% to 25%. A 1mm wall can withstand ± 2000 Pa, and factory spiral forming is 30% faster. They have low air leakage, energy and material savings, and are suitable for machine room main pipelines and high-speed systems; Rectangular shape can be attached with beams and columns, flange matching box, aspect ratio ≤ 4:1, suitable for corridor ceilings and low-speed branch pipes, but the four corners need to be reinforced to pass the fire resistance test
