HSS Steel Pipe-Definition/Shapes/Size/Specifications

Table of Contents

HSS steel is a kind of hollow structure profile steel with high performance and high quality. With its unique structure and excellent performance, hss steel has been widely used in the engineering field, and gradually changing the face of engineering construction.

This paper will discuss the application and development of HSS steel pipe in modern engineering from the definition of HSS steel pipe, HSS steel pipe materials and a variety of shapes of pipes.

HSS Steel Pipe Meaning And Material

HSS Steel Pipe-HSS Definition Steel

HSS Steel Pipe is a type of steel with a hollow section. There are many shapes and sizes such as square, rectangle and circle. The manufacturing process is usually made by cold bending or hot rolling. The unique hollow structure of HSS steel pipe makes the pipe of this structure have a higher section modulus and moment of inertia, and can withstand a larger bending moment and torque.

On the other hand, due to the unique hollow structure design of hss tube steel, the weight of the steel pipe is relatively light, and it is light and fast in the transportation and installation process.

HSS Steel Tube Material And Property

Steel HSS is a tool steel material containing high carbon, high tungsten, high molybdenum, high chromium and other alloying elements.

The most common metal materials for hollow section pipes are carbon steel (CS), stainless steel (SS), aluminum (Al) and copper (Cu).

HSS-Steel has high hardness, high red hardness, high wear resistance, good toughness and high corrosion resistance. These characteristics enable the project to maintain good structural stability under extreme conditions of high temperature and pressure.

HSS Steel Pipe/Circular Hollow Section(CHS) Chart

The diagram of circular hollow section usually includes the main specification parameters such as inside and outside diameter, wall thickness and so on.

Through the table provided by Pandapipe, you can clearly see the characteristics of different sizes of CHS, so as to select the appropriate steel pipe.

HSS Steel Pipe/Rectangular Hollow Sections(RHS)

Rectangular Hollow Sections Pipe (RHS) is a kind of hollow steel pipe with rectangular cross-section, which shows better mechanical properties under pressure, bending moment and torque. By welding the steel plate into a rectangular cross-section shape, and then after grinding, painting and other subsequent processing to get the finished product.

HSS Steel Pipe/Square Hollow Sections(SHS)

Square hollow steel pipe (SHS) is square, and the four corners are right angles. This makes the SHS more uniform in all directions when subjected to pressure, bending moments and torques, thus improving the overall structural stability.

HSS Steel Conclusion

The high performance of HSS Steel makes it play an increasingly important role in modern engineering. In the future, steel hss will continue to develop a wide range of application fields and make greater contributions to the development of human society.
