Polishing of the inner wall of stainless steel tanks
Thread Content
Semiconductor companies require the inner walls of stainless steel tanks to be polished to a level where RY is less than 0.7μm. What does this requirement mean? Which polishing companies in China are recommended?
This thing is used with polishing powder and similar materials for polishing, right?
Electrolytic polishing is used – are you familiar with it? Which one is better
This is too technical; you could ask Nantong CIMC whether they are capable of handling it. If not, it’s recommended to post a request on the ‘Gas Community’.
I’ve found that there are many more companies in the HaiChuan area engaged in other chemical industries, with fewer dealing with high-purity gases
Electrolysis or chemical polishing is rarely used in the chemical industry; for relevant information, it is recommended that the original poster consult those in the pharmaceutical and food industries, or those involved in the design and manufacturing of high-precision machinery :) I don’t have any contact with manufacturers, so I can’t be of any help
There are many products in the pharmaceutical and food categories; indeed, thank you
Definition of Ra: Arithmetic mean deviation of the profile: the arithmetic average of the absolute values of the profile deviations over the sampling length. Definition of Ry: Maximum contour height: the distance between the top line of the contour peaks and the bottom line of the contour valleys within the sampling length. Ry has basically been abolished. Currently, Ra is the parameter commonly used to evaluate surface roughness.
If the customer makes such a request, there’s nothing we can do; the key is to find a reliable manufacturer who can fulfill it
