Стандарт устанавливают общие технические условия на бесшовные приварные отводы из углеродистой и низколегированной стали.
Отводы типа 3Д с R=1,5Ду с углом поворота 45, 60, 90, 180° применяют для трубопроводов различного назначения, включая подконтрольные органам надзора, при Ру до 16,0 МПа и температуре от -70°С до +450°С.

Условия применения (эксплуатации) отводов устанавливают на основе результатов расчетов на прочность с учетом всех внешних и внутренних силовых воздействий, свойств транспортируемых по трубопроводу веществ и окружающей среды.
Диаметр отводов исполнения 2 от 32 до 426 мм.
Пример условного обозначения отвода 90°, исполнения 2, диаметр 108 мм, Т=4 мм из стали 20:
Отвод 90°-108х4 ГОСТ 17375-01,
Тоже для трубопроводов, подконтрольных органам надзора из стали 09Г2С:
Отвод П 90°-108х4 09Г2С ГОСТ 17375-01.
