摘要： The invention relates to a multilayer plastic pipe (1), preferably for use in heating systems. The multilayer pipe comprises an inner core (2) and a barrier layer (6) surrounding the core and preventing oxygen diffusion through the multilayered pipe. The core (2) is made of a material having viscoelastic properties, preferably cross-linked polyethylene, and the barrier layer (6) is surrounded by an outer layer (8) of a material having adhesive properties. The invention also relates to the use of a multilayer pipe for providing pipe couplings.
摘要翻译：本发明涉及一种多层塑料管（1），优选用于加热系统。多层管包括内芯（2）和围绕芯的阻挡层（6），并防止氧扩散通过多层管。芯（2）由具有粘弹性的材料制成，优选为交联聚乙烯，阻挡层（6）由具有粘合性质的材料的外层（8）围绕。本发明还涉及用于提供管接头的多层管的用途。

摘要： The present invention relates to a pipe coupling for connection to a pipe end of a pipe made of polymer material and intended preferably for tap water or heating installations. The pipe coupling includes an inner sleeve intended for insertion into the pipe end and for abutment with the inner surface of said pipe end. The coupling further includes an outer sleeve intended for abutment with the outer surface of said pipe end. The outer sleeve is provided with a slot-like opening and means for adjusting the width of said opening. When the outer sleeve is in a tightened, adjusted state, the sleeve will be internally and externally cylindrical. A center axis through the outer cylindrical surface of the outer sleeve is spaced at a distance from a center axis through the inner cylindrical surface of the outer sleeve. In the tightened, adjusted state of the outer sleeve, the internal radius of said sleeve is smaller than the external radius of said pipe end.
