Practical aspects of the coupling of such pipes are described. In particular, the reasons for the increase in requirements to the quality of welded joints with the enlargement of the pipe diameter are stated. The design of the coupling with tapered cuffs, as well as the assembly technique of this type of coupling is considered. Two technologies – the electrofusion welding of large-diameter pipes using cylindrical couplings, and the electrofusion welding of pipes by means of couplings with tapered cuffs – are compared. In conclusion, a list of the European regulations on which the welds made by means of couplings with tapered cuffs are tested, is given. </p></abstract><trans-abstract xml:lang="ru"><p>Рассмотрена концепция соединения труб большого диаметра методом электромуфтовой сварки при помощи муфт с коническими манжетами. Описаны практические аспекты выполнения соединений таких труб. В частности, указываются причины роста требований к качеству сварных соединений с ростом диаметра соединяемых труб. Рассмотрена конструкция муфты с коническими манжетами, а также технология монтажа данного вида муфт. Приводится сравнение двух технологий — электромуфтовой сварки труб большого диаметра при помощи цилиндрических муфт и электромуфтовой сварки труб при помощи муфт с коническими манжетами. В заключении приводится список европейских нормативных документов, на основании которых испытываются сварные соединения, выполненные при помощи муфт с коническими манжетами.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>полиэтиленовые трубы</kwd><kwd>сварка с закладными нагревателями</kwd><kwd>конические манжеты</kwd><kwd>внутреннее армирова-ние муфт</kwd><kwd>трубопроводные системы</kwd><kwd>техника соединения труб большого диаметра.</kwd></kwd-group><kwd-group xml:lang="en"><kwd>PE pipes</kwd><kwd>welding with embedded heaters</kwd><kwd>tapered cuffs</kwd><kwd>internal coupling armoring</kwd><kwd>pipeline systems</kwd><kwd>coupling technique for large-diameter pipes.</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">DVGW GW 335-B2:2004-09 «Kunststoff-Rohrleitungssysteme in der Gas- und Wasser - verteilung; Anforderungen und Prüfungen – Teil B2: Formstücke aus PE 80 und PE 100».</mixed-citation><mixed-citation xml:lang="en">DVGW GW 335-B2:2004-09 «Kunststoff-Rohrleitungssysteme in der Gas- und Wasser - verteilung; Anforderungen und Prüfungen – Teil B2: Formstücke aus PE 80 und PE 100».</mixed-citation></citation-alternatives></ref><ref id="cit2"><label>2</label><citation-alternatives><mixed-citation xml:lang="ru">EN 12201-3:2011 «Plastics piping systems for water supply, and for drainage and sewerage under pressure - Polyethylene (PE).
