How to deal with the dirt on the surface of stainless steel seamless pipe?

Stainless steel seamless pipes (SS SMLS pipes) are prone to accumulating dirt when stored in warehouses for extended periods. If not cleaned promptly, this dirt can lead to corrosion, diminishing the pipe’s quality and making it appear less polished. This can negatively affect customer perception and ultimately impact sales and company profits. Therefore, proper care and cleaning of stainless steel seamless pipes are essential. Here’s how to effectively remove dirt and maintain these pipes.

Methods for Cleaning Dirt on Stainless Steel Seamless Pipes:

General Dirt and Dust:

For easily removable dust and dirt, the pipe can be cleaned with soap, a mild detergent, or warm water. Marks such as labels and paint films can be removed similarly using warm water and weak detergents. Adhesive residues can be wiped off using alcohol or organic solvents like ether or benzene. For greasy or oily substances, a soft cloth can be used to wipe the area, followed by cleaning with a neutral detergent, ammonia solution, or a special cleaning product.

Rainbow Stains:

Rainbow-like discolorations on the surface of stainless steel pipes are often caused by excess detergent or oil. To remove these, use warm water with a neutral detergent for cleaning.

Rust and Stubborn Dirt:

Rust or other tough dirt on the surface can be treated with a 10% nitric acid solution, abrasives, or specific cleaning chemicals designed for stainless steel. Regular cleaning and maintenance can help prolong the pipe's lifespan, keeping it shiny and corrosion-free.

Chemical Residue:

If stainless steel pipes come into contact with bleach, various acids, or other corrosive substances, they should be washed immediately with water, followed by soaking in an ammonia solution or neutral carbonated soda. Afterward, clean the surface with neutral detergent or warm water.

Special Considerations:

In environments with frequent acid-base reactions (such as chemical plants, pickling plants, galvanizing plants, or generator rooms), stainless steel pipes are exposed to acidic or alkaline gases, which can accelerate corrosion. Weekly inspections should be conducted to remove any foreign matter from the pipe surfaces. Otherwise, rust can form easily.

For stainless steel used in dark, damp, and poorly ventilated environments, regular monthly inspections are recommended. If water stains or rust appear, they should be cleaned promptly to prevent further corrosion. For stainless steel pipes in standard conditions, it is advisable to clean and wipe them every two to three months, ensuring they avoid contact with cement, acids, and alkaline substances.

By following these maintenance practices, stainless steel seamless pipes can remain clean, shiny, and corrosion-free, enhancing their appearance and durability.
