Aluminum alloy pipes contain a large amount of water, impurities and oil, and form weak acidic gas, which corrodes seamless steel pipes, especially the welded parts or damaged parts. Artificial welding is easy to form false welding points, easy to leak, and the leakage points are difficult to find. The initial pressure drop caused by rough pipe wall is large, which increases energy consumption. For every 1 bar increase in pressure drop, the power of the air compressor shall be increased by at least 7%.

Because the main component of carbon steel pipe is iron, this element is easy to react with water and oxygen in the air to produce iron oxide (rust). This material will be transmitted to the cylinder and production equipment along with compressed air, resulting in cylinder wear and equipment damage and unnecessary loss to the user. If the air source comes into direct contact with the product, the quality will be reduced. If it is food products, the impact will be more severe!

Even if the filter triplet is selected, because rust is a solid impurity, it is very easy to adsorb on the filter material, resulting in too short service life of the filter material and pressure drop. Another point is the pressure drop of traditional pipeline; For newly installed carbon steel pipes, the inner wall is rough (internal roughness is 1.9 μ m), and the roughness increases year by year due to corrosion, which directly leads to flow reduction and pressure drop.

The last point of damage comes from the leakage problem of traditional pipelines. The cause of leakage is corrosion. No matter whether the carbon steel pipeline with threading device or welding device is selected, the corrosion always begins at the wire mouth and welding scar. The severe one is directly broken through on the right side of the figure to form leakage. The pressure pipeline with nominal diameter less than 150mm and high working pressure less than 1.6Mpa (gauge pressure) is non-toxic, non combustible The pipeline without corrosive gas and the pipeline of the equipment body are outside. Among them, the safety supervision and management of oil and natural gas pipelines shall also be implemented in accordance with the law on safe production, the law on the protection of oil and natural gas pipelines and other laws and regulations.
