Труба Din стандарт 11850
Стандарт DIN 11850 разработан для труб из нержавеющей стали для систем
трубопроводов в пищевой, фармацевтической и химической промышленностях. Данные
трубы изготовливаются из стандартных марок сталей AISI 304 (1,4301) и AISI 316 (1,4404)
Шероховатость нержавеющих труб стандарта 11850 минимальна (< 0,8мкм, область сварного
шва < 1,6 мкм ) и соответствует гигиеническим требованиям, предъявляемым к нержавеющим
трубам, применяемым для транспорта таких пищевых продуктов как молоко и
кисломолочная продукция. В тоже время электросварная труба ДИН 11850 гораздо дешевле,
а значит и экономичнее, цельнотянутой трубы.
Обозначение для труб согласно данному стандарту должно содержать:
•наименование (труба);
•номер данного стандарта (DIN 11850);
•характеристические размеры трубы (наружный диаметр трубы Х толщину стенки);
•номер стандарта, касающийся указаний относительно испытаний (сварные трубы согласно
DIN 17457 класс испытаний 1 или класс испытаний 2);
•номер материала марки стали согласно DIN EN 10088-1;
•условное обозначения исполнения.
