Stainless Steel Tubing Production

Stainless steel tubing and piping can be crafted as either welded or seamless varieties, each with its unique manufacturing method. Welded steel tubes are formed by merging and sealing the edges of raw steel, while seamless steel tubes are produced through stretching or drawing techniques. In producing welded stainless steel pipes, manufacturers begin with hot-rolled or cold-rolled steel coils or strips. These coils are shaped into a rounded, tubular form as they pass through grooved rollers. Welding electrodes then join the processed coils along a seam using electrical resistance welding. Post-welding, residue is typically cleaned both inside and out. The tube is subsequently resized to its final dimensions by two semicircular rollers. This welding method ensures high precision and eliminates the necessity for secondary processes.

Manufacturers create seamless tubing and pipes using a method called drawing, akin to extrusion. Unlike traditional hot metal extrusion, which uses high temperatures and a die to push molten metal through, drawing involves pulling a solid stainless-steel billet over a bullet-shaped piercing rod with tensile force. This process forms a hollow, seam-free cylinder. Drawing is usually conducted at ambient temperature but can be performed at higher temperatures to minimize stress on hollow sections. The production of seamless tubes concludes at a reducing mill, where the tube is temporarily shaped into an oval for final processing before being reshaped by a rotary sizer. The main benefit of seamless stainless-steel tubing and piping is its enhanced resistance to splitting, enabling it to endure greater pressure.

Metal turning, or spin forming, involves rotating a flat round disc of sheet metal on a spinning CNC lathe. This method offers low production costs and reduces material waste. However, it is limited to producing concentric shapes.
