ОСТ 36-41-81 - Сварные и гнутые детали трубопроводов
Сварные и гнутые детали трубопроводов на Ру до 10 МПа (100 кгс/см2), предназначенные для соединения сварных и бесшовных труб из углеродистой стали.
Материал деталей и температурные пределы их применения следует принимать такими же, как и для соединяемых труб.
Изготавливаем нестандартное оборудование по чертежам заказчика
