Size DN25 DN20 304 / 316 weldable steel tubing Not Annealed Dairy Finish DIN11850
This product range provides a wide range of tubes with internal surface finishes that have a roughness average (Ra) of < 0.8 - 1.6 μ. Tubes in the hygienice range comply with DIN 11850.
Surface Polish:
Surface finish is 20 u-in Ra (0.5um) ID maximum, 30 u-in Ra (0.8um) OD maximum surface roughness measured per ASME/ANSI B46.1 with the profilo-meter reading at 90 degree to the lay. Other finishes available upon request.
Our Stainless Steel HygienicTube:
1. Complies with DIN 11850 to ensure maximum compatibility with your process system.
2.Wide range of tube OD sizes available to suit your application (see Table below).
3. Tube lengths cut to order for ease of shipping etc.
4. Fully annealed option to ensure ease of fabrication and manipulation if required.
5. Full certification provided on request thus providing full traceability.
Export Packaging:
As a final step to ensure purity standards, each tube is packaged using 2 mil poly sleeving and both ends are sealed using air tight end caps. Stainless steel sanitary pipes are packaged in protective tri-wall boxing. When specified, woode boxes and all export requirements can be provided.
