Surface treatment of steel pipes after welding after stainless steel re-rolling
The properties of stainless steel are obtained through the unique alloy composition, in which chromium plays a leading role. Chromium combines with oxygen to form an extremely thin and extremely hard chromium oxide film, which protects the underlying stainless steel. In the presence of a chromium...Read more -
What are the causes and detection methods of oil and gas steel pipeline leaks
There are many reasons for steel pipeline leakage, which can be mainly divided into three categories: corrosion perforation, fatigue rupture, and external force damage. Although corrosion control measures can significantly slow corrosion, they cannot prevent it. When cathodic protection is insuff...Read more
