Основная функция отводов — изменение углового направления участков трубопровода. Надежность отводов крутоизогнутых обеспечивается отсутствием швов на трубах. Технология изготовления крутоизогнутых бесшовных отводов путем деформации отрезка трубы на специализированной форме. Данная технология обеспечивает изготовление отводов крутоизогнутых бесшовных по ГОСТ 17375 высокого качества. Отводы изготавливаются как из углеродистых сталей типа Сталь20, так и высоколегированных 10Х18Н10Т. Радиус изгиба отвода бесшовного может составлять от 1 Ду до 1,5 Ду, где Ду- условный диаметр заготовки. Отводы бесшовные стальные могут иметь углы изгиба 300, 450, 600 и 900. Отводы крутоизогнутые изготовляются диаметрами от 18 мм до 820 мм, и давлением до 16 Мпа. Отводы приварные 3D c R≈1,5 DN и Ɵ=600, Ɵ=900 и Ɵ=1800, изготавливают протяжкой или штамповкой. Возможность изготовления из марки стали: ст.3, ст.20, ст.09Г2С, ст.15Х15М, ст.12Х18Н10Т, ст.10Х17Н13МТ.
