Surface Finish Options
Biopharmaceutical Applications
Upstream Processing: ≤ 0.5 µm Ra, electropolished preferred
Downstream Processing: ≤ 0.38 µm Ra, mandatory electropolish
WFI Systems: ≤ 0.25 µm Ra, full electropolish with 100% inspection
Pharmaceutical Applications
API Manufacturing: ≤ 0.5 µm Ra, depends on product compatibility
Formulation/Filling: ≤ 0.38 µm Ra, electropolished
CIP/SIP Systems: ≤ 0.38 µm Ra, corrosion-resistant finish

ASME BPE tubes(Bioprocessing Equipment) refers to high-purity stainless steel tubing manufactured, finished, and tested in strict compliance with the ASME BPE Standard. This global standard governs the design, materials, fabrication, and surface finishes of equipment and systems used in sanitary or hygienic applications, primarily within the biopharmaceutical, pharmaceutical, food, beverage, and personal care industries.
Biopharmaceutical: Purified Water (PW), Water-for-Injection (WFI), Clean-in-Place (CIP), Steam-in-Place (SIP) lines, fermentation, cell culture, and purification process piping.
Pharmaceutical: Process fluids, solvent distribution, API (Active Pharmaceutical Ingredient) manufacturing.
Food & Beverage: High-purity ingredient transfer, final product filling.
Cosmetics & Personal Care: High-value product manufacturing.
