In the future, it may be combined with new materials to improve antibacterial or heat transfer capabilities and be used in medical or new energy fields.
Advantages of Electropolished Pipe
- By selectively removing iron and impurities, Electropolishing adds a passive chromium oxide layer to the surface. This substantially increases the tubing’s pitting and crevice corrosion resistance, which is favorable in harsh environments like chemical processing or marine applications.
- The electrochemical process achieves an ultra-smooth finish, with surface roughness values as low as Ra 0.25 μm or below. This minimizes friction, reduces adhesion of contaminants, and enhances flow characteristics.
- The mirror-like finish eliminates microscopic irregularities where bacteria or particles could lodge, ensuring compliance with stringent sanitary standards. This makes electropolished stainless steel tubing a preferred choice for food, beverage, and biomedical applications requiring impeccable cleanliness.
- Mechanical integrity as well as fatigue failure resistance is greatly improved in the tubing after electropolishing because surface micro-cracks and stresses are removed.
- The process steps results of a uniform, bright, and reflective surface that improves aesthetics, while retaining functionality and protecting features. Such uniformity is useful in construction as well as in the case of stainless steel tubes of appealing grade manufactured in steel that seek uniformity.
Manufacturing Process
- Stainless steels like 304 and 316L are picked due to their corrosion resisting capabilities. The tubing is produced from seamless cold drawing, or welding (TIG or laser), which provides a solid homogeneous base for subsequent operations.
- The tubing undergoes annealing in a controlled atmosphere (e.g., hydrogen or nitrogen mix) at 1010-1120°C, followed by rapid cooling. This relieves internal stresses, refines the microstructure, and enhances ductility, preparing the surface for electropolishing.
- Before electropolishing, the tube is cleaned (i.e., degreased and rinsed) to remove contaminants, oils, or scale from forming and annealing. This guarantees a starting uniform surface which is important for consistently achieving good results during electropolishing.
- The tubing is immersed in an electrolyte solution (typically phosphoric and sulfuric acid) and subjected to an electric current. This selectively removes surface material, smoothing micro-irregularities, reducing roughness to Ra 0.25 μm or lower, and enriching the chromium oxide layer for superior corrosion resistance.
- Completed tubing is subjected to non-destructive testing such as eddy current tests or hydrostatic tests to check for any structural or surface defects. Subsequently, the tubing is dried with high-purity nitrogen and, for cleanliness and sterility purposes, packaged in a cleanroom classified as ISO 4 or 5.
