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 [...]

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 [...]
