Abstract

Danas se u svijetu gotovo sve kompanije i društva koja upravljaju cjevovodima pridržavaju skupa pravila i
preporuka koje je izdalo Američko društvo mehaničkih inženjera pod nazivom ''ASME Code For Pressure
Piping''. Budući da se ovaj diplomski rad bavi plinovodima, postupcima izgradnje, ispitivanjima i održavanjem
plinovoda, a sve se te radnje provode prema pravilima propisanim u publikaciji koja se naziva B 31.8 – Sustavi
cjevovoda za transport i distribuciju plina. (engl.: ''B31.8 – Gas Transmission And Distribution Piping
Systems'') veliki je dio rada izrađen u skladu s tom publikacijom. Nakon izgradnje novog plinovoda obavljaju
se potrebna ispitivanja i istraživanja, nakon čega se donosi odluka da je plinovod ispravan i spreman za
korištenje. U svakom se slučaju stanje sustava ispituje dvanaest mjeseci nakon instalacije. Osim tlačnog
ispitivanja, često se vrši i inspekcija cjevovoda uređajima koji omogućavaju uvid u stanje plinovoda (engl.
''smart pigs''). Takva se ispitivanja izvode i tijekom radnog vijeka cjevovoda, a prikupljeni podaci omogućuju
njegovo pravilno i pravovremeno održavanje, čime se produljuje radni vijek plinovoda. Većina uređaja za
kontrolu ispravnosti plinovoda koji se koriste danas određuju mjesto, intenzitet ili vrstu oštećenja nekog dijela
plinovoda u skladu sa dizajnom i namjenom samog uređaja. Svrha tih uređaja je sakupljanje podataka za
kasniju obradu.

Abstract (english)

Abstract: Today, all companies that operate natural gas transport systems consider a group of recommedations issued by ''American Association of Mechanical Engineers'' (ASME) code B31.8 – Gas Transmission and Distribution Piping Systems; ASME code for pressure piping. After finishing the construction of a new pipeline, operating companies must provide certificates about all test and inspections regarding to the new pipelines safety and reliability. All companies must inspect the system status no longer than twelve months after finishing the constructuion. In case that inspection concludes the existance of corrosive enviroment, it is recommended to use active cathode protection. The in line inspection actually implies the use smart pigs, as machines that provide information about the status of the pipeline, its malfunctions and errors. Most of the machines used today provide information about the place, intensity and type of the error.
