What is electro polishing process?
Electropolishing is an electrochemical finishing process that removes a thin layer of material from a metal part, typically stainless steel or similar alloys. The process leaves a shiny, smooth, ultra-clean surface finish. Both are non-mechanical, chemical processes, but only electropolishing uses electrical current.
What acid is used in electropolishing?
The most widely used electrolytes for the electropolishing of stainless steel are varying concentrations of phosphoric and sulphuric acid, and occasionally additives such as chromic acid.
What is electropolished pipe?
Electropolished Stainless Steel Tubing is used for biotechnology, semiconductor and in pharmaceutical applications. Electropolishing is a process through with the absolute roughness of the Electropolished Stainless Steel Pipe is reduced.
What is the difference between electroplating and electropolishing?
The main difference between Electropolishing and Electroplating is: Electro-Polishing REMOVES surface metal by ionic dissolution. Electro-Plating DEPOSITS/ADDS a layer of metal onto the part by ionic deposition.
Does electropolishing improve surface finish?
The electropolishing process may improve a surface finish by up to 50%. The electropolishing reaction removes material while it improves surface roughness. Because of the material removal, process runtimes are often limited to maintain dimensional tolerances.
What is the purpose of electropolishing?
Electropolishing removes surface material and surface contaminants. Electropolishing dissolves free iron, inclusions, and embedded particles from the surface of the material surface. Electropolishing improves the near surface chemistry of stainless steel.
How is the material removed in electropolishing process?
How is the material removed in Electropolishing process? Explanation: Material in Electropolishing is removed by anodic dissolution process.
Is electropolishing a coating?
Benefit: Improved Aesthetic Value However, because electropolishing is not a coating you won’t have the problem with the surface chipping or peeling exposing the base material. Electropolishing leaves parts with a bright, shiny finish indefinitely. This appearance is the most notable feature of an electropolished part.
Which one is better hand polishing vs electropolishing?
Electropolishing: The Clear Advantage Electropolishing is 30 times more effective than chemical passivation. Unlike mechanical polishing, electropolishing removes a uniform layer of surface material to create a smooth surface free of debris or other contaminants.
How is electropolishing used in the polishing process?
Electropolishing is an electrochemical finishing process that removes a thin layer of material from a metal part, typically stainless steel or similar alloys. The process leaves a shiny, smooth, ultra-clean surface finish. Also known as electrochemical polishing, anodic polishing or electrolytic polishing, electropolishing is especially useful
What are the steps in electropolishing stainless steel?

Why are stainless steel EP tubing and pipes electropolished?
Electropolishing is a process through with the absolute roughness of the Electropolished Stainless Steel Pipe is reduced. This makes the pipes more accurate in dimensions and the Ep Pipe can be installed with accuracy in sensitive systems like the pharmaceutical industrial applications. There are different materials that could be electropolished.
What kind of Finish do you need for electropolished pipe?
The finishing of electroplating has different standards for use in different applications. These applications require medium range of finish. Electropolishing is a process through with the absolute roughness of the Electropolished Stainless Steel Pipe is reduced.
