Stainless Steel Sanitary Tubes for CIP Systems in Milk Industry

CIP System for Milk Industry

A typical CIP system in the milk production process.

In milk production, the clean-in-place (CIP) system is essential, ensuring that equipment and pipelines are thoroughly cleaned between production batches to prevent contamination and microbial growth. Specifically, the CIP system is responsible for cleaning and disinfecting the milk transport line, storage tanks, pumps, and valves at the end of each production batch. It operates through an automated cleaning process, using acidic and alkaline solutions, hot water, and other cleaning agents to flush the interiors of tubes and equipment, removing mineral deposits, protein, and fat residues to maintain sterility in production equipment and prevent product contamination.

Application & Characteristics of SS Sanitary Tubing

ASTM A270 welded TP316 sanitary tubes supplied to Australia.

Metalsin supplies seamless or welded stainless steel sanitary tubes for CIP systems in milk industry. These tubes are usually manufactured in accordance in ASTM A270 available in material grades of TP304, TP304L, TP316, and TP316L. In the dairy industry’s CIP system, stainless steel sanitary tubing is crucial for maintaining hygiene and preventing contamination. This tubing connects various cleaning components, such as central tanks, pipelines, storage tanks, pumps, and valves, allowing for the circulation of acidic and alkaline cleaning solutions and high-temperature water through dairy processing equipment. Its corrosion resistance enables it to withstand frequent exposure to cleaning chemicals without releasing harmful metal ions, while the smooth inner surface (typically with a roughness below 0.8 µm) prevents residue buildup and microbial growth, ensuring effective cleaning and sterility. The tubing’s durability, high-temperature resistance, and mechanical strength make it ideal for the CIP system, supporting strict food safety standards in milk production.
