Beschreibung
Zusammenfassung:	A pipeline laid trenchlessly and/or without a sand bed is produced using a metallic conduit which is encased with an extruded layer of a polyamide moulding material. In this way, the durability of the outer shell required for trenchless laying techniques without a sand bed is ensured. L'invention concerne une conduite posée sans tranchée et/ou sans lit de sable, ladite conduite étant obtenue par une conduite métallique enrobée d'une couche extrudée en matière moulable polyamide, ce qui garantit la résistance de l'enveloppe externe requise pour les techniques de pose sans tranchée ou sans lit de sable.
