Примечание: резьбу М135×4 при проектировании новых трубопроводов не применять. Масса тройника указана с фланцами, не более.
Условное обозначение
Пример: Тройник 4—65×40—100—20Х3МВФ — ГОСТ 22801-83
Здесь: исполнение 4, Ду 65 мм, Ду' 40 мм, Ру 100 МПа, материал — сталь 20Х3МВФ (по ГОСТ 22790-89, табл. 1).
Условия применения
Тройники ГОСТ 22801-83 применяются в трубопроводных системах нефтехимической промышленности и производства минеральных удобрений при сверхвысоких давлениях от 10 до 100 МПа. Конструкция предусматривает два типа тройников: проходной (Ду = Ду') и переходный (Ду ≠ Ду'). Уплотнение — линзовое. Фланцы основного прохода — по ГОСТ 9399-81. Технические требования к изготовлению, материалам и контролю — по ГОСТ 22790-89.
