What are the special design requirements for Cable tray in terms of anti-corrosion?

Publish Time: 2024-03-28
Cable tray's special design requirements in terms of anti-corrosion are mainly due to the complex environment it may face in practical applications. In harsh environments such as moisture, acid and alkali, cable trays are susceptible to corrosion, affecting their service life and safety. Therefore, anti-corrosion design has become an indispensable part of the Cable tray manufacturing and installation process.
First, material selection is key to corrosion protection design. Cable trays usually use materials with good corrosion resistance, such as stainless steel, galvanized steel, aluminum alloy, etc. These materials have good corrosion resistance and can be used in harsh environments for a long time. The stainless steel bridge itself has good corrosion resistance, but in special environments, special corrosion-resistant coatings may be needed; galvanized steel bridges are hot-dip galvanized to form a uniform and dense zinc layer on the surface, providing Excellent anti-corrosion performance; the aluminum alloy bridge is oxidized or anodized to form an oxide film to provide anti-corrosion protection.
Secondly, the application of anti-corrosion coating is also an important means of anti-corrosion design of Cable tray. For metal bridges, anti-corrosion coatings can be coated on their surfaces, such as epoxy resin coatings, polyester powder coatings, etc. These coatings form a protective film that prevents corrosive media from directly contacting the bridge surface. In special environments, you can also choose to use advanced technologies such as corrosion-resistant vapor corrosion inhibition (VCI) bimetallic inorganic anti-corrosion coatings to further improve the anti-corrosion performance of the cable tray.
In addition, environmental control is also an important aspect of the anti-corrosion design of Cable tray. In special environments such as chemical factories and coastal areas, environmental control measures need to be taken, such as controlling humidity, temperature and chemical media, to reduce the corrosion impact on the Cable tray.
Finally, during the design and installation process, the cable tray also needs to follow relevant standards and specifications to ensure the effectiveness and compliance of the anti-corrosion design. These standards and specifications usually include requirements for material selection, coating thickness, coating type, construction methods, etc., providing clear guidance for the anti-corrosion design of Cable trays.
To sum up, the special anti-corrosion design requirements of Cable trays involve many aspects such as material selection, anti-corrosion coating application, and environmental control. Through reasonable anti-corrosion design, the cable tray can ensure long-term stable operation in harsh environments and improve the safety and reliability of the cable system.
