How to prevent your steel hollow section from damages in applications？

Corrosion prevention can take a number of forms based on the specific circumstances where the metal tube has being corroded. Generally speaking, steel pipe corrosion occurs when it is exposed to moisture and other elements or chemicals. As it is generally a natural process it can lead to a severe decrease in the functionality and esthetics of steel pipes. Therefore, it is believed that a successful corrosion control program is a never ending practice. It begins with an effective design and installation of the pipeline, executing corrosion control methods, and maintaining and monitoring the lines.

Here, as a professional steel pipe manufacturer in China, DongPengBoDa Steel Pipe Group would like to introduce couples of useful methods of protecting pipe against corrosion in various applications as follows:
1) Turn to non-corrosive metals such as aluminum and stainless steel.
2) Keep the area around the metal surface dry.
3) Use drying agents and moisture barrier products.
4) Make sure underground piping is laid in a layer of backfill, such as limestone.
5) Make sure any electrical components are cleaned regularly
Of course, apart from the mentioned suggestions above, there are a few other tips for corrosion prevention of pipelines in life, for instance a coating of grease or oil maintained on a metal surface. Painting is another important method to be used for most structural steel pipes from corrosion in applications. Also cathodic protection is another important method to prevent corrosion on the primary metal pieces. Specifically, painting has an advantage when appearance and choice of color are important. Modern painting systems may be appropriate protection in certain environments. Paint provides “barrier” protection to a metal surface. In addition,the ability of zinc to provide cathodoic protection for carbon steel in addition to barrier protection is a fundamental advantage.

Technically, corrosion is a natural process, which converts a refined metal to a more stable form, such as its oxide, hydroxide, or sulfide. It is the gradual destruction of materials (usually metals) by chemical and/or electrochemical reaction with their environment. In real life, corrosion and repair of corrosion damage are multi-billion dollar problems. Estimates show steel corrosion costs the United States approximately $297 billion annually, or about 3% the national GDP. In that regards, it explains that high costs of production will cause the relatively high steel pipe price in the pipe market.
