Speaking of steel pipe materials, now the professional manufacturers of steel pipe manufacturers are constantly improving the quality requirements, but some necessary wear and tear is indispensable. Sometimes there is oxidation corrosion now. What is the reason for it?
The reason of vibration corrosion is that vibration effect destroys the protective film of AM2 high pressure boiler tube, rapid oxidation, repeated wear and oxidation of bare metal, and aggravates the damage. In addition, the metal surface of the ASTM A192 high pressure boiler tube is subjected to pressure caused by cold welding or melting, and then the relative movement of metal particles falls off and oxidizes rapidly. Both of them produce oxidized rust particles that destroy the metal interface. Oxygen is very important in vibration corrosion, but some vibration corrosion do not need oxygen. ASTM A192 high pressure boiler tube protection method can be applied to contact grease, reduce friction, and remove oxygen, if the surface is phosphated at the same time more effectively. Cemented carbide, shot peening or cold working can also be used to improve surface hardness.
