What Is Stainless Steel Polished Pipe?
Stainless Steel Polished Pipe is a stainless steel pipe with a smooth, refined surface achieved through mechanical polishing or electropolishing. Depending on the application, it can feature a satin, brushed, or mirror finish on the outer surface, with inner surface polishing available where required. This finishing process improves the pipe’s appearance and makes cleaning easier by reducing surface irregularities where dirt and residue can collect. These pipes are widely used in architectural projects, food processing, pharmaceutical equipment, and industrial applications that require a clean finish and good corrosion resistance.

Materials and Grades of Stainless Steel Polished Pipe
We manufacture and supply Stainless Steel Polished Pipes in different grades to meet the needs of various industrial, architectural, and hygienic applications. Each grade offers specific properties that help determine its suitability based on corrosion exposure, fabrication requirements, and surface finish.
Stainless Steel 304: Offers good corrosion resistance and a smooth finish, making it suitable for handrails, kitchens, food processing equipment, and indoor installations.
Stainless Steel 304L: Its low carbon content makes it a suitable choice for applications involving extensive welding.
Stainless Steel 316: Contains molybdenum, which improves resistance to chlorides and many corrosive environments. It is commonly used in coastal, marine, and outdoor applications.
Stainless Steel 316L: Combines low carbon content with good corrosion resistance, making it suitable for pharmaceutical equipment, biotechnology facilities, and hygienic systems.
The right grade depends on the working environment and intended use. Even with a high-quality polished finish, selecting a suitable stainless steel grade remains essential for maintaining corrosion resistance, appearance, and long-term performance.
Polish Grades and Surface Finishes of Stainless Steel Polished Pipe
Surface roughness is measured as Ra in micrometres. The lower the Ra, the smoother the surface. Values below are typical and vary with grade and process.
| Finish | Grit | Approx. Ra (µm) | Look | Common use |
|---|---|---|---|---|
| No. 4 satin | 150–180 | 0.4 – 1.0 | Soft linear grain | Handrails, kitchens, facades |
| Fine satin | 240 | 0.4 – 0.6 | Smooth, even grain | Food and dairy lines |
| Extra fine satin | 320 | 0.25 – 0.4 | Very fine grain | Pharma and interiors |
| Mirror (No. 8) | 400 and above, then buffed | 0.05 – 0.15 | Reflective shine | Architecture and decor |
| Electropolished | After mechanical polish | 0.2 – 0.5 | Bright, smooth, sealed | Pharma, biotech, semiconductor |
Mechanical Polish vs Electropolished Stainless Steel Pipe: Which Do You Need?
| Point | Mechanical polish | Electropolish |
|---|---|---|
| Method | Abrasive grinding and buffing | Electrochemical removal of a thin surface layer |
| Surface | Smooth, with fine directional scratches | Smoother, free of micro-scratches |
| Corrosion resistance | Good after passivation | Higher, with more chromium-rich surface |
| Cleanability | Good | Best |
| Look | Satin to mirror | Bright, uniform shine |
| Cost | Lower | Higher |
| Best for | Handrails, food, dairy, decor | Pharma, biotech, semiconductor, high-purity lines |
Choose mechanical polish for decorative work and general hygienic service. Choose electropolish when cleanability and purity are critical, or when the line carries pure water, clean steam or high-purity gas.

Stainless Steel Polished Pipe Size and Weight Chart
Theoretical weight is (OD − Wall) × Wall × 0.02491 for 304 and 304L, and × 0.02507 for 316 and 316L, giving kg per metre with dimensions in mm. Real weight varies slightly within mill tolerance.
Use factor 0.02491 for 304 / 304L and 0.02507 for 316 / 316L. OD and wall are in mm. Multiply the result by the pipe length to obtain the total weight.

FAQs
Common questions about stainless steel polished pipe, finishes, welding, Ra values and supply.
Which finish is best for food and dairy lines?
A fine satin of 240 grit or finer, or electropolish, with Ra of 0.8 µm or lower. Both are smooth enough to clean well and meet common hygiene rules.
Is 304 or 316 better for polished pipe?
Use 304 indoors and in food lines. Use 316 near the sea, outdoors in polluted air or where chlorides are present.
Can polished pipe be welded?
Yes. Welding leaves heat marks, so the area should be ground, re-polished and passivated to restore both the look and the corrosion resistance.
What is the difference between No. 4 satin and mirror finish?
No. 4 has a soft brushed grain that hides fingerprints. Mirror finish is buffed to a reflective shine that shows every mark.
What does the Ra value mean?
Ra is the average surface roughness in micrometres. A lower number means a smoother surface that is easier to clean.
How do I calculate the weight of a polished pipe?
Use (OD − Wall) × Wall × 0.02491 for 304 and 0.02507 for 316, with both values in mm, to get kg per metre.
Which documents come with an order?
EN 10204 3.1 mill test certificates are included. Ra reports, PMI reports and third-party certificates are available on request.
Can you make custom sizes and lengths?
Yes. Special OD and wall combinations, cut lengths and end preparation are made to your drawing.
How is polished pipe packed for export?
Each length is wrapped in protective film or paper, bundled and strapped or crated. Heat numbers are marked on each bundle for traceability.
