Surface treatment methods and usage environment of seamless tubes

Surface treatment methods of seamless tubes & pipes:

Seamless tubes require surface treatment during production and use to ensure smooth surface, corrosion resistance, rust prevention and other properties, and to extend service life. Commonly used surface treatment methods include:

1. Spray paint
Spray painting is a common surface treatment method for seamless steel tubes. Spraying a layer of paint can effectively prevent rust and corrosion on the surface of steel pipes, and can also beautify the appearance of steel pipes. The color and type of spray paint can be selected according to the use environment and requirements.

2. Galvanized

Galvanizing is also a common surface treatment method for seamless steel tubes. During the production and processing process, the steel pipe is immersed in a zinc-containing solution to form a galvanized layer, which can effectively prevent the steel pipe from rusting and corrosion and extend its service life. The thickness and zinc content of the galvanized layer can also be adjusted according to the usage requirements.

3. Sandblasting
Sandblasting is a mechanical surface treatment method that uses high-speed ejection of abrasive particles to sand, polish, and decontaminate the surface of steel pipes. This can improve the surface quality of the steel pipe and make the coating adhere more closely. The degree of sandblasting can be adjusted according to the requirements of use.

4. Apply anti-corrosion coating
Coating a layer of anti-corrosion paint is one of the commonly used surface treatment methods, which can effectively prevent rust and corrosion on the surface of seamless tubes, and can also improve the surface smoothness and aesthetics of steel pipes. The type and thickness of the anti-corrosion coating can be selected according to the usage requirements.

Selection of surface treatment methods under different usage environments:

Different use environments require different seamless tube surface treatment methods to ensure the performance and service life of the steel pipe.

1. Indoor use: Seamless steel tubes used indoors can choose surface treatment methods such as spray painting, coating or galvanizing.
2. Outdoor use: Seamless steel tubes for outdoor use require surface treatment that can prevent rain, sun, and corrosion. Various surface treatment methods such as galvanizing, sandblasting, and anti-corrosion coating can be selected.
3. Use in marine environment: Seamless steel tubes in marine environment require very strong corrosion resistance. You can choose to sandblast, spray paint or apply a layer of anti-corrosion paint for treatment.

In short, the correct choice of seamless tube surface treatment methods can effectively extend the service life of steel pipes and improve the performance of steel pipes. When choosing a surface treatment method, you need to consider many factors such as the use environment, use requirements, and application scenarios.

Tips: ASTM A106 (ASME SA106) seamless pipes can transport fluids or gases under high temperature and pressure. There are three grades: A, B, and C. The most commonly used ASTM A106 grade B is widely used in oil and natural gas refineries, power plants, petrochemical project factories, and boilers. and ship construction. These pipelines must carry fluids and gases that exhibit higher temperature and pressure levels.
