Dimension Range

Stainless steel pipe is a hollow, elongated steel material widely used as a pipeline for transporting fluids such as oil, natural gas, water, coal gas, steam, etc. In addition, it is lighter in weight when bent and has the same torsional strength, so it is also widely used in the manufacture of mechanical parts and engineering structures. It is also commonly used for producing various conventional weapons, barrels, shells, etc.

Classification of pipes: Steel pipes are divided into two categories: seamless steel pipes and welded steel pipes (welded pipes). According to the cross-sectional shape, it can be divided into circular pipes and irregular pipes. Circular steel pipes are widely used, but there are also some irregular steel pipes such as square, rectangular, semi-circular, hexagonal, equilateral triangle, octagonal, etc.
Seamless stainless steel pipe, also known as stainless steel seamless pipe, is made by piercing steel ingots or solid billets into rough tubes, and then hot rolling, cold rolling or cold drawing them. The specifications of seamless steel pipes are expressed in millimeters by the outer diameter multiplied by the wall thickness. The full name of 304 stainless steel pipe is SUS304 stainless steel pipe
SUS304 stainless steel pipe belongs to the stainless steel pipe of American grade material, and the domestic grade is equivalent to 0Cr19Ni9 stainless steel pipe, usually replaced by 0Cr18Ni9. The mechanism of stainless steel rust prevention is the formation of a dense oxide film by alloy elements, which isolates oxygen contact and prevents further oxidation. So stainless steel is not "stainless".

The types and uses of stainless steel pipes mainly include the following aspects:

Type:

Classified by material: Stainless steel pipes are mainly divided into 304 stainless steel and 316 stainless steel. 304 stainless steel has good corrosion resistance and mechanical properties, and is suitable for general industrial, construction, and decoration fields. 316 stainless steel has better corrosion resistance and is suitable for fields such as chemical, marine, and pharmaceutical industries, with good resistance to corrosive media.
Classified by purpose: Stainless steel pipes can be used for transporting fluids, manufacturing mechanical parts and engineering structures, producing conventional weapons, gun barrels, shells, and as furniture and kitchenware.
Classified by production method: including seamless pipes and welded pipes. Seamless pipes are made by cold drawing, extrusion, cold rolling and other methods, while welded pipes are made by gas shielded welding, arc welding, resistance welding and other methods.
Purpose:

Industrial applications: Widely used in industrial transportation pipelines and mechanical structural components such as petroleum, chemical, medical, food, light industry, and mechanical instruments.
Civilian applications: Used for manufacturing decorative projects such as stair handrails, guardrails, anti-theft windows, as well as bathroom product pipes, fluid pipes, etc.
In summary, stainless steel pipes have been widely used in various fields due to their excellent corrosion resistance and lightweight characteristics. Stainless steel pipes of different materials are suitable for different environments and needs, from general industrial applications to special military applications, showcasing their unique advantages and value.
