Фланцевое присоединение к процессу, мембранные разделители
Описание
Диафрагменные разделители применяются для защиты приборов измерения давления при сложных условиях эксплуатации. Эти системы с диафрагменным разделителем, состоящие из технологического преобразователя, датчика давления, манометра или реле давления с диафрагменным разделителем, могут подбираться индивидуально для каждого применения заказчика. Для этого доступен широкий выбор различных конструкций, технологических присоединений, типов монтажа и материалов, контактирующих со средой.
Модели диафрагменных разделителей с фланцевыми присоединениями доступны с заподлицовыми или внутренними диафрагмами, в трубчатом исполнении или в виде диафрагменных разделителей для установки в линию.
Особенности
- Компактное ячеечное исполнение
- Промежуточный фланец с открытой (проточной) мембраной
- Доступны стандартные исполнения и номинальные размеры
- Большой выбор различных материалов и их комбинаций
- Присоединение прибора через радиальный адаптер манометра
Вопросы и ответы
Какие фланцевые стандарты и номинальные диаметры доступны?
Фланцы по DIN EN 1092-1, ASME B16.5-2017, GOST 33259 и JIS B2220; номинальные диаметры DN 40 … DN 125 (включая варианты DN 40A … DN 100A) и дюймовые размеры 1 ½", 2", 3", 4", 5".
Какие материалы доступны для частей, контактирующих со средой?
Широкий выбор: сплавы Hastelloy, Inconel, Incoloy, Monel, никель, титан, тантал, нержавеющие стали (316L, 904L, 321, 316Ti, Duplex 2205, Superduplex 2507), а также покрытия PFA, ECTFE, золото и Wikaramic®.
Из чего выполнен корпус?
Из нержавеющей стали 1.4404 (316L) или титана grade 7 (3.7235).
Какие сертификаты доступны для 990.28?
NACE MR0175 / ISO 15156, NACE MR0103 / ISO 17945, а также испытательные свидетельства EN 10204 2.2 и EN 10204 3.1.
Подходит ли 990.28 для взрывоопасных зон?
Да, в комплекте с моделью 910.21 с предкамерным пламегасителем допускается применение в зоне 0 (EPL Ga).
Чем 990.28 отличается от других мембранных разделителей серии 990?
Это компактное исполнение клеточного типа с промежуточным фланцем и заподлицо расположенной мембраной, предназначенное для агрессивных, вязких, кристаллизующихся или горячих сред и высоконапорных применений; присоединение прибора выполняется через радиальный адаптер для манометра.
