Stainless steel sanitary tube FAQ

Sanitary tubes typically have a smoother surface finish, such as mirror or bright annealed, and are manufactured to stricter dimensional and material standards to ensure there are no crevices or pits where bacteria could grow.
They are often cleaned with clean-in-place (CIP) methods using chemical sanitizers or hot water and steam, and they can also be sterilized with steam-in-place (SIP).
Lower surface roughness reduces the likelihood of contamination and makes the tubes easier to clean, ensuring a high standard of hygiene and reducing the risk of product spoilage.
Sanitary-grade tubes feature a smoother surface finish, typically with Ra (Roughness Average) values below 0.8 micrometers to prevent bacterial growth and product buildup, and undergo more rigorous testing and documentation to meet sanitary standards, along with stricter adherence to tolerances and dimensions (diameter, wall thickness) for sanitary applications.
Yes, they are commonly used in systems requiring ultra-pure water, such as in semiconductor and pharmaceutical manufacturing, due to their non-reactive surfaces and resistance to corrosion.
Yes, stainless steel is a highly recyclable material, and sanitary tubes can be fully recycled at the end of their service life, contributing to sustainability efforts.
Stainless steel sanitary tubes must adhere to stringent standards, including 3-A Sanitary Standards, ASTM A270 for surface finish and material grades, ASME BPE (Bioprocessing Equipment Standard) for bioprocessing equipment, ISO 2037, and EN 10357 for the food, pharmaceutical, chemical and biotechnology industries. Additionally, they should comply with FDA (Food and Drug Administration) regulations for safe contact with food and pharmaceutical products. Proper documentation is essential for verifying compliance and maintaining traceability.
