How to Remove the Oil Stain on the Surface of Galvanized Pipe?

The oil stain on the surface of the galvanized pipe (GI Pipe) can be removed with some special cleaning agents. Generally speaking, you can choose to use solvent-based cleaning agents or water-based cleaning agents with better degreasing effects. Specifically, different cleaning agents can be selected according to the type of oil stain and the degree of pollution.

Some common cleaning agents include industrial alkaline cleaners, strong detergency solvent cleaners, and environmentally friendly water-based cleaners. Among them, water-based cleaning agents are easy to use, non-polluting, and have good environmental protection performance, which is an excellent choice. When cleaning, you can choose brushing, spraying, soaking and other methods to clean according to the specific situation. At the same time, it is also necessary to pay attention to the selection of appropriate cleaning process parameters, such as temperature, time, concentration, etc., in order to achieve a good cleaning effect.

What are the cleaning methods for hot-dip galvanized pipes?

There is a dense protective film on the surface of the hot-dip galvanized pipe, which will not be easily damaged or rusted during later use. Due to the influence of the installation site, environment, temperature and humidity and other conditions, regular cleaning is required for better use. So what are the specific cleaning methods?

1. Wash with clean water
This is a simple and direct cleaning method, just clean the inside of the hot-dip galvanized pipe directly with clean water. However, this cleaning method can only remove floating ash on the surface, and impurities such as dirt and silt in the steel pipe cannot be completely removed, and the cleaning effect is not very obvious.

2. Potion cleaning
Add a certain amount of chemical reagents to the water for cleaning. During the cleaning process, the chemical agent can easily remove the dirt, and it will also cause strong corrosion to the steel pipe while decontaminating, thus shortening the service life of the steel pipe. Generally, this method is not often used.

3. Physical cleaning

Physical cleaning is powered by compressed air, using a launcher to add special ammunition to the hot-dip galvanized steel pipe, so that it can fully contact with the inner wall of the steel pipe, and the friction generated can achieve the cleaning effect. This cleaning method will not cause damage to the steel pipe, and it is the most used cleaning method so far.

Notes:
In order to effectively clean the oil and dust of galvanized pipes, in addition to using the correct cleaning method, you also need to pay attention to the following matters:

1. Make adequate preparations before cleaning, including choosing the right cleaning agent, tools, and items needed.
2. Choose the right cleaning method for the specific situation, and mix it according to the specified ratio when cleaning, and avoid using too much or too little cleaning agent.
3. Wear protective equipment during operation to avoid contact with the cleaning agent. At the same time, pay attention to ventilation to ensure a safe working environment.
4. Rinse thoroughly after cleaning to avoid residual cleaning agent from damaging the galvanized pipe.

Avoid the generation of oil stains on the surface of galvanized square tubes?

When using galvanized square tubes, oil stains may remain on the surface and need to be cleaned. In addition to choosing the correct cleaning method, you should also pay attention to how to avoid the generation of surface oil stains. Here are a few suggestions:

1. Storage method
After the galvanized square pipe is placed for a long time, dust and oil stains are easy to accumulate on the surface. Therefore, when storing pipes, you should choose a dry, ventilated, pollution-free place, place the pipes vertically, and avoid collisions and squeezing between pipes.

2. Handling method
When handling galvanized square tubes, workers should wear work clothes and use professional tools such as ropes or chains for safe handling. Avoid pulling or collision on the surface of the pipe.

3. Usage method
When using galvanized square pipes, mechanical friction and polishing should be avoided on the surface of the pipe to avoid damaging the protective layer on the surface of the pipe. Similarly, moisture and water should be avoided on the surface of the pipe to avoid rust on the surface.

The above are the three cleaning methods of hot-dip galvanized pipe, I hope it will be helpful to you. Choosing the right cleaning agent and cleaning method, choosing the right tools, and carefully following the cleaning steps can effectively remove the oil stains on the surface of the galvanized steel pipe; and following the correct storage, handling and use methods can avoid the generation of surface oil stains and ensure the quality and appearance of the pipe.
