      Description

      DIN EN 10357 was developed for seam welded tubes made of stainless steel for pipeline systems in the food, pharmaceutical and chemical industries. DIN EN 10357 (2014-3) replaces DIN 11850 at the beginning of 2014. Fundamental changes to DIN 11850: - Tube series 1 and 2 have been replaced and supplemented by series A to D. - Series A replaces DIN series 2, series B replaces DIN series 1, series C corresponds to ISO and series D corresponds to OD and SMS.
