Abstract

Zgodnie ze zgłoszeniem zapewniony jest układ do detekcji i monitorowania uszkodzeń spoin (2) gazociągów w zmiennych warunkach pomiaru, zwłaszcza obciążeń oraz temperatury, charakteryzujący się tym, że zawiera moduł akwizycji i analizy danych (3) wyposażony w obwód generatora, pomiaru i analizy sygnału elektrycznego; przetworniki piezoelektryczne (4a - 4h), czujniki odkształceń (5a, 5b) i czujnik temperatury (6), umieszczone na monitorowanym gazociągu (1) w otoczeniu spoiny (2) oraz połączone niezależnie z modułem akwizycji i analizy danych (3). Przetworniki (4a – 4h) tworzą powiązane ze sobą funkcjonalnie pary, przy czym w ramach każdej pary jeden przetwornik piezoelektryczny (4a — 4d) umieszczony po jednej stronie spoiny (2) i zasilany przez moduł akwizycji i analizy danych (3) jest przeznaczony do wzbudzania w monitorowanym gazociągu (1) fali sprężystej, a drugi przetwornik piezoelektryczny (4e — 4h) umieszczony po drugiej stronie spoiny (2) jest przeznaczony do wytwarzania napięcia elektrycznego wywołanego docierającą do niego falą sprężystą przechodzącą przez spoinę (2). Moduł akwizycji i analizy danych (3) służy do oceny ryzyka wystąpienia lub powstania uszkodzenia spoiny (2) poprzez porównanie rejestrowanego sygnału elektrycznego przetwornika piezoelektrycznego każdej funkcjonalnej pary z sygnałem referencyjnym dobieranym z uwzględnieniem zmiennych warunków pomiarowych na podstawie wskazań czujników odkształceń (5a, 5b) i czujnika temperatury (6). Zgodnie ze zgłoszeniem zapewniony jest także odpowiedni sposób detekcji i monitorowania uszkodzeń spoin (2) gazociągów w zmiennych warunkach pomiaru.According to the application, a system is provided for detecting and monitoring damage to welds (2) of gas pipelines under variable measurement conditions, especially loads and temperatures, characterized by the fact that it includes a data acquisition and analysis module (3) equipped with an electric signal generator, measurement and analysis circuit. ; piezoelectric transducers (4a - 4h), strain sensors (5a, 5b) and a temperature sensor (6), placed on the monitored gas pipeline (1) near the weld (2) and connected independently to the data acquisition and analysis module (3). The transducers (4a - 4h) form functionally related pairs, and within each pair one piezoelectric transducer (4a - 4d) placed on one side of the weld (2) and powered by the data acquisition and analysis module (3) is intended to excite elastic wave in the monitored gas pipeline (1), and the second piezoelectric transducer (4e - 4h) placed on the other side of the weld (2) is intended to generate the electric voltage caused by the incoming elastic wave passing through the weld (2). The data acquisition and analysis module (3) is used to assess the risk of occurrence or damage to the weld (2) by comparing the recorded electrical signal of the piezoelectric transducer of each functional pair with a reference signal selected taking into account variable measurement conditions based on the indications of strain sensors (5a, 5b) and temperature sensor (6). According to the application, an appropriate method of detecting and monitoring damage to welds (2) of gas pipelines under variable measurement conditions is also provided.
