Knowledge of rolling surface processing of stainless steel pipe:
1. After hot rolling, annealing, pickling, and descaling, the surface of the treated stainless steel plate is a dull surface and a bit rough;
2. It is a better process than the general surface, and it is also a dull surface. After cold rolling, annealing, descaling, and finally light rolling with a rough roll;
3. This is the most commonly used in construction applications. Except for the last mild cold rolling with a polishing roller after annealing and descaling, the other processes are the same as 2D, the surface is slightly shiny, and it can be polished;
4. Bright annealing:
(a) This is a reflective surface, which is rolled by polishing rolls and finally annealed in a controlled atmosphere;
(b) Bright annealing still maintains its reflective surface and does not produce an oxide scale.
