The long-term use of the air storage tank or after many years of use will inevitably cause rain, air or humid atmospheric corrosion, which is caused by the action of water, oxygen, acidic pollutants and other substances in the atmosphere. It is a common atmospheric corrosion phenomenon that steel rusts in the atmospheric natural environment. The selection of filler metal for aluminum alloy pipeline is not only dependent on the composition of the base metal, but also related to the geometry of the joint, the corrosion resistance requirements in operation and the appearance requirements of the welded parts.

It plays an active role in the whole industrial automation process, can reduce unnecessary energy consumption and waste in the gas transmission process, provide high-quality gas quality, and reduce leakage and pressure drop; Ensure safe, stable and high-quality clean air is delivered to the user. In order to make the container have good corrosion resistance or prevent the stored products from polluting it, the welded container for storing hydrogen peroxide requires high-purity aluminum alloy. In this case, the purity of the filler metal should be at least equivalent to that of the base metal.

The styles and models of aluminum alloy pipes are rich and varied, and the product characteristics are also determined according to the market demand. The company strives to adapt the aluminum oxide pipes to the changes of the market and meet the needs of customers. With the development and innovation, the aluminum alloy pipes of composite central air conditioning have relatively low requirements for installation accuracy, which can improve the installation speed of central air conditioning ventilation pipes. Ventilation duct system is a kind of facility established for air circulation and reducing harmful substances.
