Stainless Steel Pipe De-greasing, Cleaning and Passivation
Stainless Steel Pipe De-greasing, Cleaning and Passivation I. De-greasing of Stainless Steel Pipes Before cleaning and passivating stainless steel pipes, they must undergo de-greasing to remove residual oils from the inner walls due to processing. Typically, industrial alcohol or dichlorodifluoromethane (CCL2F2) is used as de-greasing agents in pharmaceutical water systems. Most stainless steel pipes used in pharmaceutical water systems are [...]

What is Anti-Hydrogen Sulfide Corrosion Pipe Steel?
What is Anti-Hydrogen Sulfide Corrosion Pipe Steel? In the petrochemical industry, hydrogen sulfide (H2S) corrosion is prevalent and highly hazardous. By analyzing the mechanism of H2S corrosion, this article introduces the forms of corrosion caused by wet H2S, including hydrogen blistering, hydrogen-induced cracking (HIC), sulfide stress corrosion cracking (SSCC), and stress-assisted hydrogen-induced cracking. It highlights the relationship between the mass [...]
Definition and Classification of Steel Pipes
### Definition and Classification of Steel Pipes (Part 1) Steel pipes are hollow long steel bars that are widely used as fluid transmission pipes, such as for oil, natural gas, water, gas, steam, etc. Additionally, due to their similar bending and torsional strength but lighter weight, they are also extensively used in manufacturing mechanical parts and structural components. Steel pipes [...]
