DIN11850 Sanitary Tubes

DIN11850 Tubing for Food, Beverage & Dairy Process Lines

DIN 11850 tubing is a type of welded stainless steel tube that is used for piping systems in the food and chemical industries. It has a high standard of hygiene and corrosion resistance, as well as a smooth and crevice-free design. DIN 11850 tubing is available in different sizes, grades and finishes, depending on the application and requirements.

Testing and Packaging

To assure strict accordance with ASTM A270 and 3A, Sanitube tubing is subjected to extensive reverse bend, reverse flattening, flange, and eddy current testing. After successfully completing testing, tubes are sealed with air tight end caps and individually packaged in high quality poly sleeves. Tubes are then packaged in heavy-duty tri-wall boxing. Wood boxes are available for export shipments when specified.

Application

Biological engineering industry, food industry, pharmaceutical industry, purified water industry, electronic engineering industry, chemical fiber industry, chemical industry, paper making industry, the beer industry, highly-purified gasses industry, cosmetics industry, etc.
