Tube Adapters | Enable various connections and help eliminate difficult alignment issues.

View All Tube Fittings and Adapters

Swagelok fittings outperform others in reducing the risk of leaks and costly downtime across various industries. The advanced back ferrule design isolates stress to resist vibration, bending, and deflection, while a patented carburization process enhances strength without sacrificing corrosion resistance. Easy to install and reassemble, Swagelok fittings require less effort than alternatives.

Tube fittings and adapter fittings are available in multiple alloys to ensure chemical compatibility, with expert-led training offered for proper installation. Swagelok tube adapters can be used with any other Swagelok tube fittings eliminating the need for stocking special elbows and tees. Stainless steel Swagelok tube fittings used with 316 stainless steel and 316 Ti stainless steel alloy tubing have been tested to the requirements of ECE R110 and are also available with EC-79 certification. Swagelok offers fittings in materials that meet the metallurgical requirements of NACE MR0175/ISO 15156 and MR0103. Also, fittings manufactured from alloy 2507 and 6MO are NORSOK M-630 and M-650 compliant as standard.

Как трубные переходники помогают решить проблемы с совмещением

Трубные переходники помогают решить проблемы с совмещением и сократить потребность в запасах запчастей. Посмотрите эту демонстрацию того, как использовать трубные переходники Swagelok® для решения проблем с совмещением и обеспечения герметичного уплотнения.

трубные обжимные фитинги Swagelok и трубные переходники

С 1947 года компания Swagelok является лидером в разработке трубных обжимных фитингов, используемых в промышленных жидкостных и газовых системах.

Основатель Swagelok рассказывает о своем революционном трубном обжимном фитинге

Более 75 лет спустя фитинги Swagelok с уникальным механизмом «шарнирно-цангового» действия по-прежнему обеспечивают длительную и герметичную эксплуатацию. Конструкция обжимного типа использует уникальное «шарнирно-цанговое» действие для получения оптимальных характеристик в трех следующих ключевых характеристиках:

Обхват трубки

Шарниро-цанговое действие обеспечивает более плотный контакт/обхват трубки.

Газонепроницаемость

Переднее обжимное кольцо полирует поверхность и создает концентрированные зоны контакта как на трубке, так и на корпусе фитинга для обеспечения качественного уплотнения.

Вибрационная устойчивость

Заднее обжимное кольцо обеспечивает защиту от концентрации напряжений в зоне обхвата трубки при воздействии на соединение изгибающих напряжений, деформации или вибрации.

Конструкция трубного обжимного фитинга Swagelok®

Шарнирно-цанговая конструкция заднего обжимного кольца с усовершенствованной геометрией является стандартной для всех трубных обжимных фитингов Swagelok из нержавеющей стали размером от 1/4 до 1 дюйма (6-25 мм), что позволяет монтажникам создавать единообразные и герметичные трубные соединения. Для данных размеров запатентованы процедура закалки корпуса и сложная геометрическая форма углубления, которые обеспечивают уникальную конструкцию заднего обжимного кольца Swagelok. Шарнирно-цанговая конструкция заднего обжимного кольца улучшает характеристики и без того надежной традиционной конструкции обжимного кольца.
