Speaking of steel pipe materials, the professional manufacturers of steel pipe manufacturers are constantly improving their product quality requirements, but some necessary wear and tear is indispensable. Oxidation corrosion is sometimes present. What is the reason?
The cause of the vibration corrosion is that the vibration effect destroys the protective film of
ASTM A192 high pressure
boiler tube, and the rapid oxidation, wear and oxidation of bare metal are aggravated again and again. In addition, the metal surface of the ASTM A192 high pressure boiler tube is caused by the pressure of cold pressure welding or melting, and then the relative moving metal particles fall off and oxidize rapidly. Both produce rust particles that destroy the oxidation of metal interfaces. Oxygen is very important in vibration corrosion, but there are also some vibration corrosion that does not require oxygen. The ASTM A192 high pressure boiler tube protection method can be applied to the grease on the contact surface, which can reduce friction and remove oxygen, and if the surface is more effectively phosphating. Cemented carbide, shot peening or cold work can also be used to improve surface hardness.
