Seamless Steel Pipe Pickling Process
Posted by zora li on August 31st, 2022
The pickling process acid pickling solution is generally a mixture of various acids, mainly sulfuric acid, nitric acid and hydrofluoric acid, etc. These mixed acids are highly corrosive and have a strong oxidizing property and a high temperature of corrosive medium. This puts high demands on the corrosion resistance of anticorrosive materials. Stainless steel seamless steel pipe pickling production line process from production to waste gas recovery system, there is a strong corrosion state in all aspects, so the choice of anti-corrosion materials is directly related to the environmental recovery system of equipment, workshop floor, trench, waste water and waste gas Normal use of etc.
Seamless steel pipe pickling process
The pickling of seamless steel tubes uses solvents and emulsions to clean the surface of welded steel pipes for low-pressure fluid transport to remove oil, grease, dust, lubricants and similar organic matter, but it does not remove rust, scale, etc. from the surface of the steel. It is only used as an auxiliary means in anti-corrosion production.
Although the chemical cleaning of seamless steel pipe can make the surface reach a certain degree of cleanliness and roughness, its anchor pattern is shallow, and it is easy to cause pollution to the spiral steel pipe stacking environment. Different forms of rust cleaning methods and methods will have a certain important impact on seamless steel tubes, affecting many performances and factors. Cleaning Chinese medicines are strictly cleaned according to certain principles and methods to ensure good value in use.
The process of pickling, which is mainly based on normalizing and rusting, is as follows: wire→normalizing→pickling→washing→high-pressure water washing→rusting→thinning lime water→drying.
