The operator first understands the structure and washing requirements of the pickling equipment for stainless steel pipe processing. Be proficient in safe operation procedures and prepare necessary pickling utensils.
Operators wear necessary labor protection supplies, no less than two operators, suitable surrounding environment, and pickling requirements.
The passivation paste can be used for treatment in the workshop. The method is to remove the weld seam of the welded pipe with a stainless steel brush, and then apply the passivation paste evenly on the surface of the pipe to be treated with a brush. After 20-30 minutes, wipe off the passivation paste with a clean cloth, and then wash it with clean water several times until the weld is as bright as the other parts of the pipe.
The operator first understands the structure and requirements of the polishing equipment required. Be proficient in safe operation procedures and prepare necessary tools.
The operator wears necessary labor protection equipment, and there are no less than two operators, the surrounding environment is suitable for the requirements, and it can be ventilated.
First, rough grinding is carried out, the purpose is to remove the hard dirt left after processing. Use 120-180 mesh iron-free alumina-based grinding wheel for grinding, with a certain amount of yellow wax or sand wax.
After the rough grinding is completed, the middle grinding is carried out, and the main purpose is to remove the traces left by the rough grinding. The specific method is to use the 122-162 hemp wheel with the purple wax with better cutting force to grind once, and then use the 122-162 hemp wheel with the finer and brighter purple wax for the second time.
After the middle grinding is finished, fine grinding is carried out. The main purpose is to remove the hemp wheel pattern to achieve a mirror effect. The specific method is to use a 122-162 cotton cloth wheel to grind the surface with a large green wax, or use a 122-162 wind wheel to grind the surface with a small green wax.
When polishing, the power of the polishing machine should be determined according to the size of the polishing wheel. If the power is too small, the polishing effect will be affected. In addition, the coarse, medium, and fine grinding wheels must be separated to prevent rough particles from affecting the stainless steel surface.
