Electropolished (EP) Seamless Tube

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 for polishing and deburring parts that are fragile or have complex geometries. Electropolishing improves surface finish by reducing surface roughness by up to 50%.

Electropolishing can be thought of as reverse electroplating. Instead of adding a thin coating of positively-charged metal ions, electropolishing uses electric current to dissolve a thin layer of metal ions into an electrolyte solution.

Electropolishing of stainless steel is the most common use of electropolishing. Electropolished stainless steel has a smooth, shiny, ultra-clean finish that resists corrosion. Although nearly any metal will work, the most commonly electropolished metals are 300- and 400-series stainless steel.

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. 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.

We have our own polishing equipment and produce electrolytic polishing tubes that meet the requirements of various fields under the guidance of the Korean technical team.

Our EP Tube in  ISO14644-1  Class 5clean room conditions, each tube is purged with ultra high purity (UHP) nitrogen and then capped and double bagged. Certification qualifying the tubing’s production standards, chemical composition, material traceability, and maximum surface roughness is provided for all material.
