What is electropolished stainless steel tube?

Electropolished stainless steel tube is a type of stainless steel tubing that has undergone an electropolishing process to enhance its surface finish and cleanliness. This process involves immersing the tube in an electrolyte bath and applying a current, which removes a thin layer of material from the surface, resulting in a smooth, shiny, and ultra-clean surface. Electropolished stainless steel tubes are highly valued in industries requiring stringent sanitary conditions and corrosion resistance, such as pharmaceuticals, food and beverage processing, and semiconductor manufacturing, due to their improved microfinish, reduced surface roughness, and enhanced passivation layer.
