【発明の名称】プラスチックパイプ接続方法及びパイプ接続部
Document Type and Number:
Japanese Patent JPH0786396
Kind Code:
B2
Abstract:
The inner pipes (2a, 2b) of a double pipe system are fixedly connected to a collar (3) by welding or bonding. In order to retain the inner pipes (2a, 2b) by means of clamping jaws (4a, 4b) when producing the collar connection, the outer pipes (1a, 1b) are constructed shorter, at least by the thickness of the two clamping jaws (4a, 4b). In order to bridge this gap, an expandable intermediate ring (9, 9a) is inserted during the connection of the outer pipes (1a, 1b) by means of an electrically welded sleeve (7).
