Abstract

W wynalazku ujawniono urzadzenie do przeprowadzania hydraulicznych prób polaczen rurowych o duzej srednicy i duzej grubosci scian oraz sposób ich testowania. Po wykuciu polaczenia rurowego o duzej srednicy i duzej grubosci scian w miejscu srednicy wewnetrznej polaczenia rurowego (2) wykuwane jest wybrzuszenie polaczenia rurowego (5), plyta uszczelniajaca (3) jest spawana do wybrzuszenia, zas szczelina znajdujaca sie miedzy wybrzuszeniem a plyta uszczelniajaca jest spawana w sposób zapewniajacy uzyskanie szczelnosci. Poniewaz wybrzuszenie i polaczenie rurowe stanowia jedna calosc, wybrzuszenie moze przenosic duze sily, co zapobiega spadnieciu plyty uszczelniajacej na skutek dzialania duzego cisnienia. Spoina pelni wtedy jedynie funkcje uszczelnienia, przy czym wysokosc spoiny jest duzo mniejsza niz w przypadku konwencjonalnego urzadzenia do przeprowadzania prób hydraulicznych, co zapewnia znaczne zmniejszenie kosztów spawania. Nastepnie przeprowadzana jest próba hydrauliczna. Po zakonczeniu próby hydraulicznej wybrzuszenie jest odcinane, zas wewnetrzna sciana polaczenia rurowego jest przy wybrzuszeniu poddawana obróbce majacej na celu uzyskanie wymiarów konstrukcyjnych, co zapewnia bezpieczne przeprowadzenie do konca próby hydraulicznej, zaoszczedzenie materialów, zmniejszenie kosztów kucia polaczenia rurowego i kosztów spawania plyty uszczelniajacej, skrócenie czasu przygotowywania próby hydraulicznej oraz zmniejszenie kosztów wytwarzania.The invention discloses a device for performing hydraulic tests of large diameter and large wall thickness pipe connections and a method for testing them. After forging a pipe connection with a large diameter and a large wall thickness in the place of the inner diameter of the pipe connection (2), the bulge of the pipe connection (5) is forged, the sealing plate (3) is welded to the bulge, and the gap between the bulge and the sealing plate is welded in a way that ensures leak tightness. Because the bulge and pipe joint are one piece, the bulge can carry large forces, which prevents the sealing plate from falling due to high pressure. The weld then only performs the sealing function, the weld height being much smaller than in the case of a conventional hydraulic test device, which ensures a significant reduction in welding costs. A hydraulic test is then carried out. After the hydraulic test, the bulge is cut off, while the internal wall of the pipe joint is subjected to a bulging treatment in order to obtain construction dimensions, which ensures safe completion of the hydraulic test, saving materials, reducing the forging costs of the pipe joint and the cost of welding the sealing plate, reducing time preparing a hydraulic test and reducing manufacturing costs.
