ASTM A270 TP304 Bright Annealed Stainless Steel Sanitary Tubes For Dairy Industry , 320 / 240 Grit
Sanitary tubes are distinguished from standard industrial pipes by their stringent hygiene requirements. Unlike standard pipes that may have rough interiors, crevices, or seams that harbor bacteria, sanitary tubes are defined by crevice-free construction and verified surface smoothness. ASTM A270 TP304 Sanitary Stainless Steel Tubes are usually applied as structural components. Typically, these stainless steel sanitary tubes are used in industries like the food and beverage, medical, pharmaceutical, as well as the biological industry. ASTM A270 TP304 sanitary tubes’ inner and outside surfaces are treated with finishes or with mechanical processes to make their surface smoother, making the transitioning of the product better. YUHONG GROUP produces ASTM A270 TP304/304L, TP316/316L stainless steel sanitary tubes for many years. Our sanitary tubes’ size range from 6mm to 152.4mmOD. Their surface finish can be bright annealed, mechanical polished, electrical polished, and so on.

Surface Finish:
A. Bright Annealed (BA) Foundation
Before polishing, the welded tube undergoes Bright Annealing. This is a process where the tube is heated in a controlled atmosphere furnace (hydrogen or dissociated ammonia) and cooled without scale formation. This produces a smooth, bright, oxide-free surface without the need for pickling. BA finish is the ideal substrate for subsequent polishing as it is already exceptionally clean and smooth .
B. Grit Polishing (Mechanical)
Grit refers to the abrasive particle size used in the polishing belts. Higher grit = Finer finish = Lower Ra (Roughness Average) .
C. Surface Finish Selection Guide :
| Finish Type | Grit Range | Typical Application |
| Industrial/Mill | N/A | Structural, non-contact |
| Sanitary (ID) | 150-180 | General food processing |
| Sanitary (High Purity) | 240-320 | Dairy, Beverage, CIP |
| Ultra-Purity | 400+ / EP | WFI (Water for Injection), Biopharma |
