Hygienic Fittings for Safe and Reliable Processes

Safeguard process integrity and process quality with hygienic fittings for optimal safety, reliability and efficiency. Easy-to-clean hygienic fittings with internal surface finishes are designed for hygienic and high-purity applications, minimizing the risk of dead legs and microbial contamination due to crevice-free welds.

Alfa Laval hygienic fittings comply with global standards, including ISO 2037, ASME and ASME BPE dimensions, EN 10357-A, and BS 4825. Tubular fittings are made from a single piece of cold-formed stainless steel, while connections are forged from solid stainless-steel bars. Strict quality control ensures tight tolerances, uniform wall thickness, smooth weld ends, and consistent surface finish and roughness.

Users can easily access digitized material certificates through the Alfa Laval FindMyCert software tool, and real-time inventory alerts at Alfa Laval global distribution centres simplify spare part availability. Choose from unions, clamp fittings, flanges, bends, tees, reducers, tubing, connectors, anchor plates and pipe support systems. All hygienic fittings come with 3.1 Material Certificates, and aseptic stainless-steel fittings include an Alfa Laval Q-doc documentation package for full traceability.
