How to prevent your mild steel pipe from corrosion in use over time

Mild steel pipe is one of common steel frame structures widely used in a variety of construction projects today. Unlike high-carbon steel pipe, mild steel pipe has carbon contents of less than 0.18%, so this type of carbon steel pipe is easily welded while some types of high-carbon steel pipe, like stainless steel pipe require special techniques in order to properly weld the material in a mill. However, like any mental products, mild steel pipe is prone to corrosion over time. In that regard, extra care is always required for you to keep mild steel pipes from rusting always.


In most cases, mild steel pipe is available in a variety of structural shapes that are easily welded into pipe or tube and etc. Mild steel pipes and tube are easy to fabricate, readily available, and cost less than most other metals. In well protected environments, the life expectancy of mild steel pipe is 50 to 100 years. Today, cold rolled steel pipes have been used for most of the pipelines in the world, for it is not only be easily welded into place flexibly but also can somewhat avoid cracking and breaking under pressure. In addition, mild steel pipes do have a wide range of uses for a variety of applications in life, such as low pressure conveyance of gas, water, oil, air steam or other fluids. They are used in machinery, buildings, sprinkler systems, irrigation systems, and water wells. For applications where corrosion protection is critical, this type of steel pipe can be painted or galvanized in the course of production in a mill.

In the current steel pipe market, various types of mild steel pipe are used for structural purpose and mechanical & general engineering purpose, such as round steel pipe, square steel pipe, and rectangular steel pipe. As mild steel pipe has poor corrosion-resistance, it must be painted or otherwise protected and sealed in order to prevent rust from damaging it. Generally, mild steel pipe is coated with other metals such as copper, to protect itself from corrosion. In addition, there are a few other tips for protecting you mild steel pipe against corrosion in service, for instance a coating of grease or oil maintained on a metal surface. In recent years, steel pipe manufacturers in China try to make a specific surface treatment for mild steel pipe as per different requirements of customers in a mill. For example, cathodic protection is another important method to prevent corrosion on the primary metal pieces.
