Abstract : Cryogenic pressure vessels are extensively used in storage and t ransportation of liquefied gas. Thedefect s possibly emerged in cryogenic pressure vessels and the nondest ructive testing (NDT) methods applied duringfabrication and using were reviewed , including radiographic testing (RT) , ult rasonic testing (U T) , magnetic particletesting (MT) , penet rant testing ( PT) , pulsed eddy current testing ( PET) , visual testing (VT) and leak testing(L T) . The characteristics of the NDT methods for cryogenic pressure vessels were also int roduced.
Keywords :Radiographic testing ; Ult rasonic testing ; Magnetic particle testing ; Penet rant testing ; Eddy currenttesting ; Visual testing ; Leak testing ; Pressure vessel
