Beverage pipes − DIN EN 10357

In March 2014, the new EN 10357 − Austenitic, austenitic-ferritic and ferritic longitudinally
welded stainless. This is revision of DIN 11850, which is now replaced by the publication of DIN EN 10357.

One of the main new aspects in the new standards is that the additional dimension lines are included, matching former European and international standards. With the series A - D, there are 4 different lines of dimensions.

  • Series A replaced DIN 11859 line 2
  • Series B replaced DIN 11859 line 1
  • Serie C complies with ISO dimensions
  • Serie D complies with OD and SMS Maßen
