Dairy Fittings
Dairy Fittings ( Stainless Steel Material)
Dairy fittings are specialized components designed for the dairy industry to ensure hygienic, safe, and efficient transfer of milk and dairy products. These fittings are critical in maintaining the integrity of dairy processing systems by preventing contamination and ensuring compliance with stringent hygiene standards. Made primarily from high-quality stainless steel (grades 304 and 316/316L), dairy fittings are engineered for durability, corrosion resistance, and ease of cleaning.
Key Features
Hygienic Design: Smooth, crevice-free surfaces to minimize bacterial growth and facilitate cleaning.
Corrosion Resistance: Made from stainless steel (AISI 304, 316, or 316L) to withstand harsh cleaning agents and high-humidity environments.
Versatility: Available in various configurations, including elbows, tees, reducers, unions, and clamps, to suit diverse system requirements.
Compliance: Meets international standards such as DIN 11851, DIN 11853, DIN 11864, SMS, IDF, and ISO for food safety and hygiene.
Ease of Maintenance: Designed for quick assembly and disassembly, reducing downtime during cleaning and maintenance.
