Стандарт устанавливает общие технические условия на бесшовные приварные тройники (равно проходные и переходные) из углеродистой и легированной стали.
Тройники 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) тройников устанавливают на основе результатов расчетов на прочность с учетом всех внешних и внутренних силовых воздействий, свойств транспортируемых по трубопроводу веществ и окружающей среды.
Диаметр бесшовных тройников исполнения 2 от 45 до 426 мм.
Пример условного обозначения
