    • A method for joining insulated conduits (1) is disclosed, in which the bared ends (2a) of the medium-carrying pipes (2) are first interconnected in a per se known manner and a union piece (3) is thereafter placed around the resulting joint (2b), such that the union piece has an overlap on the outer side (2c) of the conduits to be joined and forms a mould for foaming an insulating material of cellular plastic in the joint (2b). The union piece is a relatively rigid, circumferentially resilient plastictube which is slotted throughout its entire length and, before being applied around the joint, has an inner diameter which is smaller than the outer diameter of the conduits (1). After the union piece has been applied around the joint, a strip (4) is placed on the slot (3a) of the union piece throughout substantially the entire length of the slot, said strip (4) consisting of a mouldable, curable plastic material which by curing is bondable to the union piece, and which is thereafter cured so as to be bonded to the union piece.
    • 公开了一种用于连接绝缘导管的方法,其中中等承载管的裸露端部首先以本身已知的方式相互连接,然后将接合件放置在所得接头周围,使得接合件在 要连接的导管的外侧,并形成用于使接头中的多孔塑料的绝缘材料发泡的模具。 联接件是相对刚性的周向弹性塑料管,其在其整个长度上开槽,并且在被施加在接头周围之前具有小于导管外径的内径。 在联接件已经被施加在接头周围之后,条带被放置在连接件的狭槽上,整个长度大体上在槽的整个长度上,所述条由可模制的可固化塑料材料组成,其通过固化可结合到联接件 然后固化,以便结合到联接件上。
