Втулка под фланецВтулка под фланец ПЭ (полиэтиленовая) – это часть трубопровода, которая применяется для соединения полиэтиленового трубопровода со стальной трубой. Также присоединяется к регулирующей или запорной арматуре с помощью фланцевого соединения.

Полиэтиленовая деталь изготавливается  согласно современным стандартам из полиэтилена ПНД невысокого давления на специальном оборудовании методом литья и с соответствующей механической обработкой. Для ее создания применяется полиэтилен марок ПЭ 80 и ПЭ 100. Втулка под фланец ПЭ 100 выпускается с такими типоразмерными характеристиками: от 20 до 1200.

Благодаря использованию ПЭ 80 и ПЭ 100 эта деталь обладает хорошими физическими и химическими характеристиками. Это обеспечивает ей долгий срок службы и позволяет широко использоваться в различных сферах с применением втулок под фланец ПНД.

Последняя производится с такими размерными характеристиками: 25 мм, 32 мм, 40 мм, 50 мм, 63 мм, 75 мм, 90 мм, 110 мм, 125 мм, 140 мм, 160 мм, 180 мм, 200 мм, 225 мм, 250 мм, 280 мм, 315 мм, 355 мм, 400 мм, 450 мм, 500 мм, 560 мм, 630 мм, 710 мм.

Эти изделия применяются в трубопроводной арматуре, которая транспортирует вещества, к которым стоек полиэтилен, например питьевая вода. Их монтаж осуществляется согласно ГОСТ 18599–2001 (если это вода) или ГОСТ Р 50838–09.


Внешний вид втулки под фланец
Суть использования такой детали заключается в том, что нужно обеспечить упор для фланца, который надет на втулку. Он исключает возможность разъединения узла во время его эксплуатации. Это означает, что при монтаже трубопровода в тех местах, где есть необходимость присоединиться к задвижке либо к какому-то другому узлу, который имеет фланцевое окончание, к трубе ПЭ приваривают втулку. Кстати, нужно заметить, что для полиэтиленовой втулки не подойдет простой стальной фланец, а нужно использовать расточенную модель.

Различают два вида втулок под фланец: короткие и удлиненные. Применяются эти два вида в одинаковых областях и имеют похожие технические характеристики. Но за счет того, что на изготовление короткой модели материала тратится намного меньше, стоимость её, естественно, тоже ниже. Когда монтируют короткую деталь, длину можно скорректировать с помощью полиэтиленовой трубы, а еще она удобна тем, что имеет меньший вес, что облегчает ее монтаж. При строительстве она применяется в трубопроводной арматуре колодцев, её легче использовать в стесненных условиях.

Изделия ПЭ используют при прокладке водопроводов и газопроводов, а еще для монтажа трубопроводных арматур, которые транспортируют химически активные элементы.

Полиэтиленовая втулка под фланец
Они играют роль бурта между прижимным и ответным фланцем трубы из стали, запорного клапана или задвижки. Эти детали изготавливаются из материала высокого качества и поэтому являются надежными, способными обеспечить 100-процентную работу трубопровода и трубы в течение всего срока службы. Втулку под фланец ПНД можно применять к любым видам полиэтиленовых труб, так как ее технические характеристики полностью соответствуют нужным стандартам, а также характеристикам полиэтиленовых труб.
