Abstract
Przedmiotem zgłoszenia jest nowa powłoka uszczelniająca w kompensatorze rurowym i kompensator rurowy liniowy, przydatny zwłaszcza w podziemnych rurociągach do transportu mediów ciekłych i gazowych. Kompensator rurowy liniowy zawiera rurę zewnętrzną (1) i osadzoną współosiowo rurę wewnętrzną (2) z zamocowanym na zewnętrznej stronie na końcu rury (2) występem (5) o wysokości równej różnicy miedzy średnicą zewnętrzną rury wewnętrznej i wewnętrzną rury zewnętrznej gdzie pomiędzy rurą wewnętrzną i rurą zewnętrzną umieszone są dwa nieruchome uszczelnienia (4 i 4') charakteryzuje się tym, że rura wewnętrzna (2) pokryta jest od strony zewnętrznej na całej długości warstwą elektroizolacyjną w postaci powłoki poliuretanowej na długości przemieszczającej się w rurze zewnętrznej przy czym rura zewnętrzna (1) i rura wewnętrzna (2) od strony wewnętrznej pokryte są warstwą elektroprzewodzącą i na końcu rury wewnętrznej (2) zamocowane jest elektroprzewodzące elastyczne pióro (3), którego przeciwległy koniec opiera się o wewnętrzna część rury wewnętrznej (1) przy czym odległość pomiędzy uszczelnieniami (4 i 4') pomiędzy rurami jest równa odległości występu (5) od bliższego uszczelnienia (4).The subject of the application is a new sealing coating in a pipe compensator and a linear pipe compensator, especially useful in underground pipelines for transporting liquid and gaseous media. The linear expansion joint includes an outer pipe (1) and a coaxially mounted inner pipe (2) with a projection (5) mounted on the outer side at the end of the pipe (2) with a height equal to the difference between the outer diameter of the inner pipe and the inner pipe where between the inner pipe and the outer tube has two fixed seals (4 and 4 ') characterized by the fact that the inner tube (2) is covered from the outside with the entire length of the insulating layer in the form of a polyurethane coating along the length moving in the outer tube with the outer tube (1) ) and the inner pipe (2) are covered with an electrically conductive layer on the inside and an electrically conductive flexible tongue (3) is attached at the end of the inner pipe (2), whose opposite end rests on the inner part of the inner pipe (1) with the distance between the seals ( 4 and 4 ') between the pipes is equal to the distance of the projection (5) from the closer seal (4).
