Stainless steel electrolytic polishing tube (EP tube) is a special purpose material which is made of bright annealing tube (BA tube) as the basic material after electrochemical polishing.
Electropolished (EP) stainless steel tubes are mainly used in precision instruments, high-purity gas or liquid transportation, semiconductor, biopharmaceutical, solar photovoltaic, and othe rindustries with high cleanliness requirements.
Through electropolishing, the surface oxide layer of the steel tube is removed, increasing the surface roughness by half compared to BA tubes, resulting in a smooth and corrosion-resistant surface.
Various materials such as 316L, 304L, nickel-based alloys, are available.
The tubes undergo ultra-pure water cleaning, nitrogen purging, single bag packaging, and packaging in a dust-free workshop.
size range : 1/16"~2"
The process is to place the bright stainless steel tube in a special chemical solution composed of a variety polishing.
The process is to place the bright stainless steel tube in a special chemical solution composed of a variety of elements,and use the anode dissolution under the conditions of electrolytic operation, so that it can obtain a very high smooth and bright surface, and form a closed layer of thick chromium oxide film on the surface.
The energy is close to the normal level of the alloy, and the amount of media is also reduced to a minimum.The inner surface roughness of the pipe can be increased to 0.20μm.
Features Of Electro Polished Stainless Steel Tube
1.To have better corrosion resistance and oxidationresistance
2.To have more smooth and mirror-like surface
3.To enhance the flow of gas or liquid in the pipeline
4.The cleaning state of the pipe is improved to improve the pipe cleanness
5.Eliminate the work hardening characteristic and obtain satIsfactory metallographic structure to eliminate the hardening to obtain satisfactory metallographic structure
