Abstract

Invenţia se referă la un înveliş pentru suprafaţa interioară a unei ţevi şi la o metodă pentru aplicarea acestuia, pe suprafaţa specificată, utilizată pentru protecţia suprafeţelor interne ale conductelor tehnologice; învelişul conţine două anvelope tubulare, peliculare (2 şi 3), localizate coaxial, pe bază de material polimeric termoplastic, dintre care una - exterioară (2) se alipeşte la suprafaţa interioară a ţevii (1), iar cealaltă - interioară (3) este separată de anvelopa exterioară (2), printr-un strat de consolidare, coaxial, principal (4), impregnat cu un liant polimeric întărit; metoda include realizarea unei părţi semifinisate, în două straturi, care se introduce în interiorul ţevii, după care se introduce agentul termic sub presiune, pentru ataşarea învelişului la suprafaţa interioară a ţevii (1). Anvelopa interioară (3) este formată dintr-un sistem omogen multicomponent, conţinând cel puţin un polimer selectat dintr-un grup de polimeri termoplastici, având alungirea relativă, nu mai mică de 200% şi temperatura punctului de topire nu mai mică de 100°C, şi un modificator structural al polimerului selectat. Anvelopele (2 şi 3) şi stratul de consolidare (4) sunt întrerupte de-a lungul generatoarei învelişului, în cel puţin un loc, iar marginile laterale (6 şi 7) ale locului de întrerupere sunt îmbinate ermetic, una cu alta, alcătuind partea semifinisatăa învelişului.
