Hygienic fittings DIN EN 10357-A

Alfa Laval Hygienic fittings DIN EN 10357-A are made of stainless steel 316L (1.4404), 304L (1.4307), 304 (1.4301) and have internal surface finish roughness average (Ra) ≤ 0.8 μm.

DIN-EN 10374-A (formerly DIN 11850) aligns with the following standards, ensuring compatibility and compliance in hygienic and aseptic applications:

• DIN 11852: Standard for welded connections, including bends, tees, reducers and tubular fittings
• DIN 11851: Standard for hygienic unions used with SS tubes ( Expanding or welding connections)
• DIN 11853: Standard for hygienic clamp, flange, and threaded connections
• DIN 32676: Standard for tri-clamp unions. Clamp connections facilitate quick assembly and disassembly of tubing systems
• DIN 11864: Standard for aseptic connections with long weld ends (for orbital weld), pharmaceutical range.
