1. Mirror treatment
Mirror treatment of stainless steel is simply to polish the surface of stainless steel. The polishing techniques are divided into physical polishing and chemical polishing. Partial polishing can also be performed on the surface of stainless steel. The polishing levels are divided into ordinary polishing, ordinary 6K, fine grinding 8K, and super fine grinding 10K. The mirror surface gives people a high-end, simple, fashionable and futuristic feeling.
2. Sand blasting
This is the most common surface treatment process for stainless steel processing. It mainly uses power obtained by compressing air. The high-speed jet beam sprays the spray material onto the surface of the workpiece that needs to be treated, causing the shape of the outer surface of the workpiece to change.
Sandblasting is mainly used in engineering and surface technology, such as improving the viscosity of bonded parts, optimizing machined surface burrs, decontamination and matte surface treatment. This process is much better than manual polishing. The surface structure after sandblasting is uniform, which can create low-key and durable features of the product, and the production and processing efficiency is high. Manual polishing can produce a matte surface but the speed is too slow, while chemical solvent cleaning will make the surface too smooth, which is not conducive to coating adhesion.
3. Chemical treatment
This process mainly uses a combination of chemistry and electrochemistry to treat a layer of stable compounds generated on the surface of stainless steel. For example, electroplating, which is common in our lives, is a type of chemical treatment.
Chemical treatment mainly relies on acidic solutions, anodized solutions, etc. alone or mixed for rust removal. Afterwards, a protective film is formed on the metal surface through chromate treatment, phosphate treatment, anodization, blackening and other methods. This process is mainly used to produce complex pattern effects and create retro or current design requirements.
4. Surface coloring
The surface coloring process of stainless steel can give stainless steel different colors, making the metal more colorful. Coloring not only makes stainless steel richer in appearance, but can also effectively improve the wear resistance and corrosion resistance of the product.
Commonly used surface coloring methods mainly include: chemical coloring, electrochemical oxidation coloring, ion deposition oxide coloring, high temperature oxidation coloring, vapor phase cracking coloring, etc.
5. Surface brushing treatment
Brushed metal is a very common decoration method in life. It can be made into straight, threaded, corrugated, random and spiral patterns. This kind of surface treatment gives people the characteristics of good hand feeling, fine gloss and strong wear resistance. It is widely used in electronic equipment, household appliances, mechanical equipment, etc.
6. Spraying
Stainless steel spray painting is very different from the coloring treatment above. Due to different materials, some spray paints may damage the oxide layer on the surface of stainless steel. However, some spray coatings can use simple processes to achieve different colors of stainless steel products, and different spray coatings can also be used to change the feel of stainless steel.
Classification of stainless steel pipes1. Classification by production method:
(1) Seamless tubes - cold drawn tubes, extruded tubes, cold rolled tubes.
(2) Welded pipe:
(a) Classification by process - gas shielded welded pipe, arc welded pipe, resistance welded pipe (high frequency, low frequency).
(b) According to welding seam - straight seam welded pipe, spiral welded pipe.
2. Classification according to cross-sectional shape: (1) circular steel pipe; (2) rectangular pipe.
Spiral steel pipe stacking requirements1. The principle requirement for stacking spiral steel pipes is to stack them according to types and specifications on the premise of ensuring stable stacking and ensuring safety. Different types of materials should be stacked separately to prevent confusion and mutual erosion;
Difference Between Straight Seam Steel Pipe and Spiral Steel Pipe
Advantages of Using Carbon Steel in ConstructionSteel is an alloy metal, which means it’s a combination of several types of elements. In the case of steel, this is a combination of iron, carbon, and trace elements. It has a number of advantages for construction applications due to the fact that it’s fairly inexpensive to manufacture and has a very high tensile strength.
What determines the type of steel is the ratio of elements used to produce it, and it’s the magic formula of the carbon steel alloy created that makes it preferred for many projects. While there are thousands of different types of steel, these types are generally bucketed into four categories: carbon steel, alloy steel, stainless steel, and tool steel.- Anti-corrosion steel pipe classificationPN8710 anti-corrosion
When there are many types of corrosive media in steel pipes, such as acids, alkalis, salts, oxidants and water vapor, the coating must be chemically inert and resistant to acid, alkali and salt corrosion. The coating film should have a dense structure, good waterproof permeability and strong adhesion. , tough and plump. In this case, IPN8710 anti-corrosion is suitable. 
Global crude steel production fell 4.3% year-on-year in MarchOn April 23, the World Steel Association (WSA) released global crude steel production data for March. In March, crude steel output in the world's 71 countries and regions included in the statistics was 161.2 million tons, a year-on-year decrease of 4.3%. In the first quarter of this year, crude steel output in the world's 71 countries and regions included in the statistics was 469 million tons, a year-on-year increase of 0.5%.
