Will Be Cold-drawn Tubes Rust? How Is It Rusty?
Apr 16, 2018

The cold-drawn tube is manufactured on the basis of cold drawing. Since the temperature of the cold-drawn tube is relatively high, the role of the cold-drawn tube in long-term use and continuous development is relatively large, and it cannot be deformed sufficiently. It can be said that the scope and frequency of the use of cold drawn tubes in steel pipes are relatively large. The cold drawn tube is not rusted according to the processing steps and the processing procedure, but due to improper maintenance and improper maintenance, the use of the cold drawn tube is also a phenomenon of rust in life. The specific reason we have for everyone to analyze:

Why does a cold-drawn tube rust? When a brown rust (dot) appears on the surface of a cold-drawn tube, people are surprised: “The cold-drawn tube does not rust, and rust is not a cold-drawn tube. It may be There is a problem with the steel." In fact, this is a one-sided misconception about the lack of understanding of the cold drawn tube. Cold drawn tubes will also rust under certain conditions.

Cold-drawn tubes have the ability to resist atmospheric oxidation - that is, stainless, but also have the ability to corrode in media containing acid, alkali, and salt - ie corrosion resistance. However, the corrosion resistance of the steel varies with the chemical composition of the steel itself, the inter-state, the conditions of use, and the type of environmental media. Such as 304 steel pipe, in the dry clean atmosphere, there is absolutely excellent resistance to corrosion, but it will be moved to the sea area, in the sea fog containing a lot of salt, will quickly rust; and 316 steel performance good. Therefore, it is not any kind of cold-drawn tube. It can resist corrosion and rust in any environment.

For the cold drawn tube, it is necessary to constantly improve the performance of various parts and promote the continuous development of the cold drawn tube. For the common performance, it is necessary to constantly ensure good results, pay attention to the usual maintenance and maintenance, When rust appears, pay attention to the way and method of rust removal, and also properly remove rust!
