Available worldwide, Alfa Laval hygienic fittings meet exacting international standards. Tubular fittings are made from a single piece of cold-formed stainless steel while connections are forged from solid stainless bars. Both undergo strict quality control measures at every stage of manufacturing. This ensures tight tolerances, uniform wall thickness, and smooth weld ends, surface finish and roughness.

Choose from unions, clamp fittings, flanges, bends, tees, reducers, tubing, connectors, anchor plates and pipe support systems. All fittings comply with ISO 2037, ASME dimensions, EN 10357-A, and BS 4825 and come with 3.1 Material Certificates. Aseptic fittings come with Alfa Laval Q-doc documentation package for full traceability of all product contact parts.


How does hygienic fittings work?

Alfa Laval tubular fittings (bends, tees and reducers) are cold-formed from a tube to the desired shape. After the forming process, the items are polished and cleaned. 

Alfa Laval machined fittings, which are in contact with the product (male, liner, blinds/end caps and ferrules), are produced from a bar or forging/bar or forging plus tube. For hygienic use, they are normally machined to the right surface finish. Our ASME BPE fittings are polished/electropolished to an appropriate smooth, highly reflective surface. 

Alfa Laval quality process and control ensures that angles and surfaces are within the standards, dimensions (diameter, wall thickness, and the length required to build in the fittings), and all other items are clean and ready for welding.
