EN10357 22mm stainless steel Instrument Tubing Food Grade For Pipeline Systems
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. With regard to EN 10357 the following normative references must be provided: DIN EN 2768, DIN 11851, DIN 11852, DIN11853-1 to -3, DIN 11864-1 to -3, DIN 32676, DIN EN 10088-1, DIN EN 10088-2, DIN EN 10204, DIN EN ISO 1127, DIN EN 10217-7
Stainless steel pipes DIN EN 10357
DIN EN 10357 - 2014 has been drawn up for welded pipes made of stainless steels for pipe line systems within the food industry, pharmaceutical and chemical industries.
