〔発明が解決しようとする問題点〕
上記従来の方法において、前者の溶着する方法では、■
作業に熟練した技術者が必要（仕上がりにばらつきが多
い）、◎第４図Ｃに示すように配管内壁に盛り上がり部
分６を生じ、使用時に核部で乱流を生じ流体抵抗を増加
させ、また核部が液だまりとなりごみがたまる。■接続

液もれを生じ、強い場合には袋ナツト４が破損する。◎
接続部に液溜りができごみが溜る。■コスト高となるＯ
φｌ′以上の太い配管には使用できない、（締付圧力が

本発明はこのような点にかんがみて創作されたもので、
作業者によるばらつきがな（、強固な接続ができ、且つ

〔作　用〕
ソケット１１を高速に回転することにより、その内径部
を配管１０　、１０　’の外径部との間に摩擦熱が発生
し、これが弗素樹脂の融点（２７ｏ〜３００’Ｃ）を越

の内径部が溶融する。この時点でソケット１１の回転を
止めれば両者の溶融部は一体となって冷却固化するため
配管１０　、１０　’はソケット１１を介して接続され
ることになる。
