Hygienic pipe and its associated fittings are used in applications requiring a clean and sanitary flow of liquids and where it is essential to avoid contamination of the products being carried. Their main use is in the dairy, food, beverage and pharmaceutical industries.

The pipe and fittings are of welded construction with the internal bead rolled to flatten it and eliminate crevices, thus preventing interruptions to the flow and eliminating the risk of contamination or bug traps as well as to facilitate easy cleaning.

Dimensions shown are in mm, if you wish to convert to Inches, please use our universal converter.
