補強された合成樹脂より成る管は周知であり且つ多数の
分野で使用される。
これらの管はその良好な機械的及び化学的性質のために

合成樹脂管を製作することが可能になって以来、鋼及び
鉄、セラミック、コンクリート及びガラスのような他の
材料より成る管と並んで使用されている。
約１〜２ｍ及びそれ以上の極めて大きい直径を有する管
の場合、特に管継手を更になお耐圧性に構成しておかね
ばならない場合、漏洩のない管継手は依然として困難で
且つ費用がかかった。
従って本発明の課題とするところは、たんに漏洩がない
だけでなく耐圧性でもあらねばならない大直径の管の継
手を構成することにあるが、しかし本発明による提案は
勿論、小口径の管にも適用することができる。
更に本発明は互いに異なる材料例えば鋼と合成樹脂並び

このような課題を本発明は次のようにして解決した。

も可能であるが、しかし上記の作業形式により迅速且つ
良好な結果が得られる。
更に、３層に積層成形された合成樹脂管において内方及
