DN25 SCH40 / SCH40s TP304 / 304L Seamless Stainless Steel Pipes ASTM A312, A213
Cold Rolling is a preferred production process for high precision seamless tube. Most of our heat exchanger tubing and mechanical tube 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 168.3mm for this process.
Cold Drawing is the general process for our tube and pipe. Pipe&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.
