What is the residual stress of welded steel pipe?
The manufacturing of welded steel pipes typically involves primary processes such as uncoiling, straightening, trimming, forming, and welding, along with a series of auxiliary processes like flaw detection, flattening, and pressure testing. Residual stress is often introduced during the rolling of the steel plate, meaning that residual stress exists in the material even before the pipe-making process begins. Operations such as uncoiling, straightening, and trimming redistribute this existing stress and may generate additional residual stress to a small extent.

Anti rust method for carbon steel pipes
Carbon steel pipes are prone to rust primarily because their main components are carbon and iron. When iron comes into contact with oxygen and water, it undergoes an oxidation reaction, forming iron oxide, commonly known as rust. Without proper protection during transportation, storage, and use, carbon steel pipes can be easily corroded by exposure to air, water, oxides, and other pollutants, leading to rust formation. In this blog, we will explore some effective methods for preventing rust on carbon steel pipes.
