Send Inquiry NowHot rolling process: Hot rolling is a common method for manufacturing stainless steel seamless pipes. During this process, the heated steel billet is placed in a rolling mill at high temperatures. Through a series of rolling and drawing steps, the blank is gradually formed into a tubular shape and reaches the desired size and thickness.
Cold drawing (cold rolling) process: Cold drawing is performed at room temperature, where a drawing machine pulls the tube blank through a die. This process reduces the diameter of the pipe and increases its length. Cold drawing improves the size and surface finish of steel pipes. It also enhances the metal’s strength.
Extrusion process: The heated metal blank is placed into a closed extrusion barrel during the extrusion process. It is extruded through a die with a specific cross-sectional shape by applying pressure. This method is suitable for producing seamless tubes with uniform wall thickness and complex cross-sectional shapes.
Perforation process: Perforation involves perforating a heated round billet using a perforator and a mandrel. The tubular shape is formed by pushing it through a mold with a mandrel. This technology is generally used to produce large-diameter, thick-walled seamless pipes.
Different production processes of stainless steel seamless pipes
Each process has its unique advantages and application areas. Manufacturers choose the appropriate production technique based on the specific requirements and applications of their stainless steel seamless pipes.
stainless steel seamless pipe VS stainless steel welded pipe
Manufacturing: Stainless steel seamless pipes are mainly produced through hot rolling, cold drawing, cold rolling, extrusion, perforation, and other processes. These processes allow metal materials to be formed into specific shapes and sizes at high or room temperatures. The result is pipes with uniform wall thickness and excellent surface quality. In contrast, stainless steel welded tube is made by bending steel plates or strips into circles or squares and then welding them together.
Performance characteristics: Stainless steel seamless pipes have high pressure-bearing capacity and good corrosion resistance because they have no welds. This feature makes them better for use in high-pressure, high-temperature, or corrosive places. Stainless steel welded pipes and tubes also have good corrosion resistance and strength. Yet, due to the welds, their pressure capacity may be slightly lower than that of seamless pipes.
Appearance and application: Stainless steel seamless pipe typically has a smoother surface and better dimensions. It is ideal for applications where pipe performance and looks matter, including the petroleum, chemical, and medical fields. Yet, stainless steel welded pipes and tubes are more flexible. We can make them into many shapes and sizes. They have many uses in construction, decoration, and machinery.

Corrosion resistant
Stainless steel seamless pipes have excellent corrosion resistance. Due to their high chromium and nickel content, these pipes can withstand corrosion from various chemicals, including acids and alkalis. Thus, seamless pipes perform well in harsh environments.
High intensity
The structural characteristics of seamless pipes give them superior strength and pressure resistance. The pipe has no welds and a uniform wall. So it can withstand higher pressure and load. It is good for high-pressure and high-temperature conditions.
Excellent machinability
Stainless steel seamless pipes have excellent machinability and plasticity. Whether cold or hot working, seamless pipes maintain good shape and dimensional stability. This facilitates next processing operations such as cutting, bending, and welding.
