Stainless steel tube has a good surface finish. It can be used as a decorative tube. It can also be processed and used as a heat exchanger tube according to its characteristics of high temperature resistance and rust prevention. But even the best surface has to be used and maintained by the user reasonably.

The high oil content of the emulsion is one of the important factors affecting the surface quality of stainless steel tubes. Emulsion can make the surface of the stainless steel tube smooth, but also can be processed when the cooling effect. But too much emulsion will decompose carbon after high temperature, and the remaining emulsion will accumulate on the surface of BA tube. It will affect its surface quality and beauty after not wiping.

Another one is carbon black. Carbon black will cling to the surface of the stainless steel tube during processing, too much carbon black will cover the smooth surface of the tube thus affecting the aesthetics. These carbon black generally appear on the stove products with stainless steel tubes, the user must often wipe.
