How are Dairy Stainless Steel Tubes different from other stainless steel pipes?

At first glance, Sanitary Stainless Steel Tubes look the same as other stainless steel pipes, even the material composition looks similar. Heres how you can tell the difference.

  • Dairy Tubes are measured by their OD, while other Schedule Pipes are measured by their Thickness.

  • To qualify as sanitary, the internal surface has to be polished to at least 150 Grit, much smoother than non sanitary tubes, markets today offer Sanitary Tubes with at least 180 Grit. 

  • The easiest way to differentiate Sanitary Tubes from tubes is the internal welding seam. Non sanitary pipes and tubes usually have a noticeable protruding welding bead. Sanitary tubes have their welding bead polished to the extent that it is difficult to feel or see, so that chances of bacterial growth is minimal.
