The Manfacturing Process of Stainless Steel Tubing

• Cold Rolling is a preferred production process for high precision seamless tubing. Most of our stainless steel tubing and mechanical tubes are made by cold rolling. This technique provides a high forming rate, narrow tolerances and good turnouts. Now the biggest diameter we can get is 219 mm for this process.
• Cold drawing is the general process for our stainless steel tube and pipe. seamless pipe and tubes from this process can be got a a very narrow tolerance ranges, and keep the chemical element well. Additionally, the cold drawing process is the perfect choice for situations which place high requirements on the quality of the surface structure.
