Переходы являют собой соединение между двумя трубами с разными диаметрами. Изготавливают переходы из разных типов стали (низколегированная, углеродистая), чугуна (ковкий, серый) и пластика. Масса перехода измеряется в (кг).
Вес переходов ГОСТ 17378-2001:
- Стальные переходы имеют много исполнений, их масса колеблется от 0.05 (кг) до 94 (кг).
Изготавливают такие переходы из сталей Р9, 09Г2С, Ст20.
Вес переходов ГОСТ 22689.2-89:
- Масса переходов из ПНП в пределах от 0.02 (кг) до 12 (кг).
Вес переходов ГОСТ 5525-88:
- Масса стандартных чугунных фланцевых переходов составляет от 9.2 (кг) до 770 (кг). Основной материал – СЧ 12.
Важно: в зависимости от сферы применения выбирается тип и материал переходов: тяжелые чугунные переходов используют в больших водопроводах, легкие пластиковые – в системах отопления с трубами малых диаметров.
