Abstract
Εις ουσιαστικώς άκαμπτος θερμοπλαστικός σωλήν, κατεσκευασμένος υπό μορφήν ισοπεδώσεως και αναδιπλώσεως, ώστε να έχη μνήμην κατά την εν λόγω συνθήκην, εναποθηκεύεται υπό την τοιαύτην μορφήν, θερμαίνεται, δια να καταστή ευλύγιστος προς εγκατάστασιν, και τοποθετείται δια της τοποθετήσεως θερμανθέντος ρευστού εις τα διατάξεις διελεύσεως κατά μήκος των πτυχών του σωλήνος, ενώ περιορίζεται το εμπρόσθιον άκρον αυτού. Το εμπρόσθιον άκρον δύναται να περιορίζεται δια σφιγκτήρος άκρου, που υποβοηθεί την διοχέτευσιν θερμού ρευστού ολοσχερώς μέσω του σωλήνος και ούτω θερμαίνει το πλήρες μήκος αυτού ή δια διογκοουμένου πώματος. Εναλλακτικώς, το διογκούμενον πώμα δύναται να προωθείται προς το εμπρόσθιον άκρον του νέου σωλήνος μετά την εισαγωγήν αυτού και εν συνεχεία να διογκούται πλήρως προς απόφραξιν του τοιούτου άκρου και τοιουτοτρόπως προς επιβοήθησιν της πλήρους στρογγυλεύσεως και εκτάσεως του εναπομένοντος τμήματος του νέου σωλήνος. ωIn the substantially rigid thermoplastic pipe, manufactured in a form of flattening and folding so as to have a memory in said condition, is stored in such form, heated to become flexible for installation, and placed by placing heated fluid in the passage devices against length of the folds of the tube, while its front end is limited. The forward end may be restricted by an end clamp, which assists the passage of hot fluid all the way through the tube and thus heats the full length thereof, or by an expanded plug. Alternatively, the inflatable plug may be advanced towards the front end of the new tube after its insertion and then fully inflated to occlude such end and thus assist in full rounding and extension of the remaining portion of the new tube. oh
