Products Description
Stainless Steel Sanitary Tubing ASTM A270 Tp304 TP316L
Advantages of Stainless Steel Sanitary Tubing ASTM A270 Tp304 TP316L
- In pharmaceutical and biotechnology applications, TP316L offers excellent resistance to pitting and crevice corrosion when exposed to chlorides or aggressive cleaning agents.
- In High-purity and chemical applications, TORICH tubing offers excellent resistance to a wide range of cleaning chemicals, disinfectants, and mild acids. The molybdenum content of TP316L gives it a distinct advantage over TP304 in chloride-rich or slightly acidic environments.
applications of Stainless Steel Sanitary Tubing ASTM A270 Tp304 TP316L
- Pharmaceutical and Biotechnology: High-purity water systems such as WFI (Water for Injection) and RO (Reverse Osmosis).
- High-purity and Chemical Processing: Handling mild chemicals, detergents, and sterilants, as well as applications requiring both hygienic and corrosion-resistant properties.
- Water Treatment and Filtration Systems: For ultrapure and deionized water distribution.
