When it comes to steel pipe materials, professional steel pipe manufacturers are now constantly improving their product quality requirements, but some necessary wear and tear is essential. Oxidation corrosion sometimes occurs, what is the reason?


The reason for the vibration corrosion is that the vibration effect destroys the protective film of the ASTM A192 high-pressure boiler tube, causing rapid oxidation of the bare metal, repeated wear and oxidation, and aggravating the damage. In addition, the metal surface of the A192 high-pressure boiler tube of the American Society for Testing and Materials is cold-welded or melted due to pressure, and then the metal particles are relatively moved off and rapidly oxidized. Both produce iron oxide rust particles that destroy the metal interface. Oxygen is important in vibrational corrosion, but there are some vibrational corrosions that do not require oxygen. The ASTM A192 high pressure boiler tube protection method can be applied to grease on the contact surface to reduce friction and remove oxygen if the surface is simultaneously phosphating more efficiently. Cemented carbide, shot peening or cold working can also be used to increase the surface hardness and the like.
