Подготовка к монтажу
Тщательная предварительная подготовка зоны сварки является обязательной процедурой!
Зона сварки должна быть полностью защищена от погодных воздействий во время снега, дождя и пр. Температура сварочного аппарата и свариваемых деталей должна быть одинаковой. Производимые компанией Georg Fischer фитинги и магнитные карты к ним упаковываются и запечатываются в полиэтиленовые пакеты сразу по завершении производственного процесса. Фитинги, доставленные на место установки в заводской упаковке, не нуждаются ни в чистке растворителем Tangit PE, ни в зачистке. Если концы труб надлежащим образом зачищены, никакого снижения качества сварки не произойдет. Зачистка фитингов-переходников требуется только при возникновении трудностей при монтаже.
Если во время монтажа произошел случайный контакт зоны сварки с каким-либо загрязненным объектом (включая прикосновение рукой к зоне сварки), фитинги или трубы необходимо тщательно очистить растворителем Tangit PE.
Зачистка
Для равномерной и быстрой зачистки зоны сварки на трубе рекомендуется воспользоваться поворотным зачистным инструментом. Зачищаемый участок трубы необходимо полностью очистить от загрязнений, а после зачистки обработать обезжиривающим чистящим раствором Tangit.
Убедитесь, что в зоне сварки не осталось незачищенных участков (это особенно важно при использовании труб в бухтах). Предел прочности и поверхностная твердость у полиэтилена ПЭ100 больше, чем у ПЭ80. Это приводит к заметному износу зачистного инструмента. В связи с этим возникает необходимость регулярной проверки и технического обслуживания подверженных износу деталей. Рекомендуемый интервал технического обслуживания зачистного инструмента – не реже одного раза в год.
Рекомендуется придерживаться следующих значений глубины зачистки:
| Диаметр трубы, мм | Минимальное уменьшение толщины стенок, мм | Минимально допустимый диаметр зачищенной трубы*, мм |
| 20 — 25 | 0,20 | d ном. — 0.4* |
| 32 — 63 | 0,20 | d ном. — 0.5* |
| 75 — 225 | 0,20 | d ном. — 0.6* |
| > 225 | 0,20 | d ном. — 0.7* |
Примечание: максимальная овальность трубы = 1.5 % (согласно стандарту DVS 2207-1)
*данные значения относятся к минимальному внешнему диаметру трубы – т.е., если средний диаметр трубы является верхним пределом допуска, при зачистке он может быть сокращен до минимально допустимого
Минимальный допустимый диаметр труб после зачистки:
| Диаметр трубы, мм | Рекомендуемая толщина зачистки, мм | Минимальный допустимый диаметр трубы после зачистки, мм |
| 20 | 0,20 | 19,6 |
| 25 | 0,20 | 24,6 |
| 32 | 0,20 | 31,5 |
| 40 | 0,20 | 39,5 |
| 50 | 0,20 | 49,5 |
| 63 | 0,20 | 62,5 |
| 75 | 0,20 | 74,4 |
| 90 | 0,20 | 89,4 |
| 110 | 0,20 | 109,4 |
| 125 | 0,20 | 124,4 |
| 140 | 0,20 | 139,4 |
| 160 | 0,20 | 159,4 |
| 180 | 0,20 | 179,4 |
| 200 | 0,20 | 199,4 |
| 225 | 0,20 | 224,4 |
| 250 | 0,20 | 249,3 |
| 280 | 0,20 | 279,3 |
| 315 | 0,20 | 314,3 |
| 355 | 0,20 | 354,3 |
| 400 | 0,20 | 399,3 |
| 450 | 0,20 | 449,3 |
| 500 | 0,20 | 499,3 |
| 560 | 0,20 | 559,3 |
| 630 | 0,20 | 629,3 |
Очистка
Для очистки труб применяются только неразбавленные быстроиспаряющиеся растворители (чистящее средство Tangit, пропитанные чистящим средством Tangit PE обезжиривающие салфетки фабричного изготовления в герметичных пластиковых контейнерах, либо вещества, соответствующие стандарту DVGW VP 603). Применение для очистки водоспиртовых составов фабричного изготовления недопустимо, поскольку содержащаяся в них вода может привести к потере качества соединения. Используемая для обезжиривания бумага должна быть чистой, неиспользованной, абсорбирующей, неволокнистой и без красителей. Допускается использование пропитанных средством Tangit PE чистящих салфеток. После очистки необходимо дождаться полного испарения растворителя.
Обезжириванию подвергают только предназначенный для сварки зачищенный участок трубы. При обработке участка большей площади возникает угроза переноса загрязнений на зачищенный участок поверхности. Если для разметки трубы используются маркеры, необходимо следить за тем, чтобы их чернила не попали в область сварки. При удалении чернил с поверхности трубы нужно следить и за тем, чтобы в области сварки не оказались и смываемые чернила. Такие меры предосторожности связаны с тем, что полное удаление чернил с зачищенного участка трубы невозможно даже при его длительной обработке чистящими средствами. Если это все же произойдет, загрязненный участок необходимо подвергнуть повторной зачистке либо заменить.
Монтаж
Трубам овального или некруглого сечения необходимо придать цилиндрическую форму в области сварки при помощи инструмента для восстановления конфигурации труб.
Крепеж труб и фитингов может осуществляется с помощью встроенных в фитинги зажимов. В случаях большого механического напряжения стыка, при монтаже дополнительно применяются двойные механические, или иные трубные зажимы. При работе с трубами в бухтах необходимо устранить механические напряжения в области сварки на протяжении всего периода сварки и охлаждения.
Пара наложенных со смещением относительно соединения трубных зажимов образует счетверенный зажим, позволяющий свести механическое напряжение на стыке практически к нулю.
Для передачи параметров сварки в сварочный аппарат используется только поставляемая вместе с фитингом магнитная карта, либо нанесенный на эту карту штрих-код. Снятие зажимов, врезка и опрессовка допустимы только по завершении периода полного охлаждения. Подробные указания по монтажу должны всегда неукоснительно соблюдаться!
При нарушении процесса сварки вследствие внешнего сбоя (например, в случае отказа генератора), процесс можно повторить, дождавшись охлаждения соединения до исходной температуры. Однако для повторной сварки необходимо:
- Определить и устранить причину сбоя. На вероятную причину укажет сообщение об ошибке на дисплее сварочного аппарата.
- Не снимать зажимы
- Дождаться полного охлаждения фитинга до температуры окружающей среды. Форсирование охлаждения (например, при помощи холодной воды) недопустимо.
Значение сопротивления фитинга на дисплее сварочного аппарата должно соответствовать исходному значению.
- Обеспечить защиту области сварки от влаги и загрязнений в течение всего периода охлаждения.
- Произвести повторную сварку согласно указаниям по монтажу и параметрам сварки на прилагаемой карте.
- Проверить герметичность соединения путем опрессовки.
Если герметичность соединения не достигнута, не повторяйте процесс сварки!
Фитинги ELGEF® Plus рассчитаны только на одну повторную сварку.

3.3.3 Current output The current output of the 2550 is set via three settings. Low current specifies the flow rate represented by the minimum current signal (4 or 0 mA). High current is the flow rate repre- sented by the maximum current (20 mA), and current selects a 4 to 20 or a 0 to 20 mA span.

Page 18: Performance Functions
3.4 Performance functions The next five main menu functions help to tailor the magmeter signals to your specific environment. 3.4.1 Sensitivity The sensitivity function limits the amount of refer- ence level noise detected by the Magmeter input circuit. Use the StdE display (sec 3.5.2) to evaluate the amount of reference noise in your system.

Page 19: Response Time
3.4.2 Response time The response time function varies the rate at which the output functions adjust to changes in the input signal. For example, if the response time is set at 10 seconds, the current output will take ten seconds to reflect 95% of any change in flow signal input .

Page 27: Custom K-Factor Calculation
3.8 Custom K-factor calculation K-factors can be calculated for any pipe using the pipe id and the ft/s engineering unit options. The procedure is based on the relationship between the frequency output and the flow velocity: 20 ft/s = 500 Hz. therefore 1 ft/s = 25 Hz. Example illustrates calculating 1.
