Cold Rolling is a preferred production process for high precision seamless stainless steel tube. Most of our heat exchanger tubes and precision tubes are cold rolled tubing. This technique provides a high forming rate, narrow tolerances and good turnouts. At present, the largest diameter we can get is 114.3mm for this processing.
Cold drawing is the common process for our ss tubings and pipes. Cold drawn stainless steel pipe will get a very narrow tolerance ranges, and keep the chemical element in a good condition. Additionally, the cold drawing process is the perfect choice for situations which place high requirements on the quality of the surface structure.
