3. Classification of Round Stainless Steel Pipes

Round stainless steel pipes are classified based on many different criteria, from chemical composition and production methods to dimensions and applications. Understanding the types of round stainless steel pipes will help you choose the most suitable product for your needs.

3.1. Classification by Chemical Composition

  • 304 Stainless Steel Pipes: The most common type of stainless steel pipe, with good corrosion resistance, high durability, easy processing, good heat resistance, and electrical conductivity. Often used in construction, food, and chemical industries.
  • 316 Stainless Steel Pipes: Have better corrosion resistance than 304, especially in environments containing salt. This type of pipe is often used in specialized industries and fields. For example, installation in projects near the sea, use in the chemical, seafood, and medical industries.
  • 201 Stainless Steel Pipes: Cheaper than 304 and 316, with lower corrosion resistance. Often used in applications that do not require high corrosion resistance. Especially suitable for environments with high temperatures and pressures. In addition, 201 round stainless steel pipes have good workability, are easy to weld and form.

3.2. Classification by Production Method

  • Welded Stainless Steel Pipes: Produced by welding stainless steel sheets together. Cheaper than seamless pipes but may have lower durability.

  • Seamless Stainless Steel Pipes: Produced by casting molten stainless steel into molds. High durability, uniform structure, and less prone to pitting.

4. Advantages of Round Stainless Steel Pipes

As one of the most widely used materials in many fields, from construction to industry. This popularity is not accidental but comes from the outstanding advantages of this material.

  • High Durability, Good Load Bearing: The round shape helps distribute force evenly over the entire pipe cross-section, enhancing the already very high load-bearing capacity and minimizing the risk of deformation.
  • Superior Corrosion Resistance: Can withstand the effects of chemicals, salts, acids, alkalis, and other harsh environmental factors.
  • Good Heat Resistance: Stainless steel has a very high melting point, allowing round stainless steel pipes to withstand high temperatures without deformation. Round stainless steel pipes have uniform thermal expansion, limiting the occurrence of thermal stresses.
  • Easy Processing: Easy to bend, cut, and weld to create products as required.
  • High Aesthetics: Round stainless steel pipes, especially decorative pipes, have a shiny surface, creating a luxurious and modern look for projects. Furthermore, the smooth surface makes it easy to clean.
  • Long Lifespan: Thanks to the above advantages, round stainless steel pipes have a very long lifespan, minimizing maintenance and replacement costs.
  • Diverse Sizes and Specifications: Many different sizes and specifications, meeting all requirements of different projects.

5. Applications of Round Stainless Steel Pipes

With outstanding advantages in durability, corrosion resistance, and aesthetics, it has become an indispensable material in many areas of life. Here are some typical applications of this type of pipe:

  • Construction and Architecture: Used as frames for construction projects thanks to high durability and good load-bearing capacity. Used to transport water, compressed air, and hot steam in construction projects. Furthermore, decorative pipes are often used as railings and handrails for stairs and balconies.
  • Industry: Used to manufacture parts of machinery and equipment in industries such as chemicals, food, and pharmaceuticals. Used to transport highly corrosive liquids and gases such as acids and bases. Used as frames for equipment and machinery that require high durability and heat resistance.
  • Food: Used to manufacture food processing equipment such as grinders, presses, and conveyors. Used to transport clean water and steam in food processing plants.
  • Medical: Round stainless steel pipes are used to manufacture medical equipment such as operating tables, hospital beds, and surgical instruments. Used to transport medical liquids and gases.

And many other applications.
