Do You Know The Three Characteristics Of Stainless Steel Duplex Pipe?

Characteristics Of Stainless Steel Duplex Pipes

Stainless steel pipes such as duplex pipe can be found everywhere in our daily use. I believe many friends are asking why there are so many stainless steel pipe products in our life. Therefore, the following three characteristics of stainless steel pipes are used. Help everyone better understand.


1, Corrosion resistance

Most stainless steel products require good corrosion resistance. Stainless steel tubes are similar to Class I and Class II cutlery, kitchen appliances, water heaters, water dispensers, etc. Some foreign traders also tested the product for corrosion resistance: using a NACL aqueous solution to warm to boiling, after a while the solution was drained, washed and dried to determine the weight loss to determine the degree of corrosion.

2, Welding processability

The requirements for soldering performance vary by product. A tableware usually does not require soldering properties and even includes some pot companies. However, most products require raw materials with good welding properties, such as second-class tableware, vacuum flasks, steel pipes, water heaters, water dispensers, etc.

3, Polishability

At present, stainless steel products are generally polished in the production process, and only a few products such as water heaters, water dispenser linings, etc. do not need to be polished. Therefore, this requires good polishing performance of the raw material. The main factors affecting the polishing performance are as follows:

  • 1 raw material surface defects. Such as scratches, pitting, soaking, etc.
  • 2 stainless steel pipe raw material problem. The hardness is too low, it is not easy to polish during polishing (BQ is not good), the hardness is too low, and the surface of the skin is prone to orange peel when deep drawing, which affects the BQ performance. High hardness BQ is relatively good.
  • 3 After deep drawing, black spots will appear on the surface of the deformed area, which will affect the BQ property.

After reading the above contents, I believe that everyone has a certain understanding of the three characteristics of stainless steel pipes and tubings, please feel free to contact us if you have any questions.
