НАЗНАЧЕНИЕ
Фланцы воротниковые широко применяются для трубопроводов среднего и высокого давления. Соединения с применением воротниковых фланцев очень удобны в монтаже и экономичны. Трудоёмкость сборки такого соединения в среднем на 20% ниже, чем сборка с применением плоских приварных фланцев. Также при использовании воротниковых фланцев вдвое сокращается объём сварочных работ.
