Many people only know the processing technology of good quality 304 100mm diameter stainless steel pipe, but do not know the specifics of stainless steel pipe processing. What are the problems in the processing of stainless steel pipe?
1. Welding seam defects: Welding seam defects are more serious, and manual and mechanical grinding treatment methods are used to make up. The grinding marks produced will cause uneven surface and affect appearance.
2. Limited pickling capacity: pickling passivation paste is not omnipotent. It is difficult to remove the black oxide scale produced by plasma cutting and flame cutting.
3. Equipment factors: scratches and creases caused during the bending and bending of profiles and plates are also the main reasons for corrosion after treatment.
4. Uneven grinding and polishing passivation: pickling passivation after manual grinding and polishing, it is difficult to achieve a uniform treatment effect for larger workpieces, and an ideal uniform surface cannot be obtained. And the cost of working hours and auxiliary materials are also higher.
5. Other factors: Good quality 304 100mm diameter stainless steel pipe raw materials during the procurement and storage process, bumps and scratches due to hoisting and transportation are also more serious, which is also one of the causes of corrosion.
6. Scratches are difficult to remove: the overall pickling passivation can not remove the various scratches produced during the processing, and can not remove the carbon steel and splashes that adhere to the surface of the stainless steel plate due to scratches and welding spatter. Impurities cause chemical corrosion or electrochemical corrosion and rust in the presence of corrosive media.
7. The scratches caused by human factors are more serious: in the process of hoisting, transportation and structural processing, the scratches caused by human factors such as bumping, dragging, and hammering are more serious, which makes the surface treatment more difficult, and it also produces rust after treatment. The main reason.
8. The surface is inconsistent: only pickling and passivation of the weld will also cause uneven surface and affect the appearance.
The editor reminds all the staff who are processing Good quality 304 100mm diameter stainless steel pipe, they must pay more attention when processing, so as to avoid possible harm to us.
