Norma GB\/T 3098.8-2010 okre\u015bla wymagania dla element\u00f3w z\u0142\u0105cznych wykonanych ze stali austenitycznych do pracy w niskich temperaturach do -200\u00b0C oraz ze stali\/stop\u00f3w niklu do pracy w wysokich temperaturach do +700\u00b0C. Obejmuje ona klasy wytrzyma\u0142o\u015bci mechanicznej, metody bada\u0144 oraz dob\u00f3r materia\u0142\u00f3w w celu zagwarantowania integralno\u015bci strukturalnej pod wp\u0142ywem napr\u0119\u017ce\u0144 termicznych. Ma to kluczowe znaczenie dla bran\u017c wymagaj\u0105cych odporno\u015bci na pe\u0142zanie, relaksacj\u0119 i kruche p\u0119kanie.<\/p>\n

      Cz\u0119sto zadawane pytania<\/h2>\n

      Jakie materia\u0142y nadaj\u0105 si\u0119 do zastosowa\u0144 w temperaturze -200\u00b0C?<\/h3>\n

      Stale austenityczne typu A4L, A4, A5 o klasie 70 lub 80, zapewniaj\u0105ce ci\u0105gliwo\u015b\u0107 i wytrzyma\u0142o\u015b\u0107 zgodnie z tabel\u0105 1.<\/p>\n

      Jak dobra\u0107 odpowiednie \u015bruby i nakr\u0119tki do wysokich temperatur?<\/h3>\n

      U\u017cyj Tabeli 3 do racjonalnego doboru par, zapewniaj\u0105c wytrzyma\u0142o\u015b\u0107 nakr\u0119tki >70% \u015bruby i w\u0142a\u015bciwe tolerancje gwintu dla pe\u0142nej no\u015bno\u015bci.<\/p>\n

      Co si\u0119 stanie, je\u015bli temperatura robocza przekroczy +700\u00b0C?<\/h3>\n

      Norma dopuszczalna jest do +700\u00b0C; w przypadku wy\u017cszych temperatur nale\u017cy przeprowadzi\u0107 specjalne testy pe\u0142zania i relaksacji zgodnie z wytycznymi normy DIN EN 10269.<\/p>\n

      Dlaczego nakr\u0119tkom austenitycznym potrzebna jest wy\u017csza granica plastyczno\u015bci?<\/h3>\n

      Aby uwzgl\u0119dni\u0107 odchylenia produkcyjne w ma\u0142ych partiach, zapewni\u0107 niezawodno\u015b\u0107 w przypadku stosowania mi\u0119kszych \u015brub (patrz tabela 3, uwaga b).<\/p>\n

      Jak sprawdzi\u0107 pe\u0142n\u0105 no\u015bno\u015b\u0107?<\/h3>\n

      Przeprowadzi\u0107 pr\u00f3by rozci\u0105gania zgodnie z norm\u0105 GB\/T 3098.1 lub 3098.6, weryfikuj\u0105c lokalizacj\u0119 p\u0119kni\u0119\u0107 i minimalne obci\u0105\u017cenia z tabel 4a\/5a.<\/p>\n

      Czy istniej\u0105 ograniczenia dotycz\u0105ce zawarto\u015bci miedzi?<\/h3>\n

      Tak, \u22641% dla stali austenitycznych w celu zapobiegania krucho\u015bci podczas pracy w niskich temperaturach.<\/p>\n<\/div>\n

      Introduction to GB\/T 3098.8 Standard This standard outlines mechanical properties, materials, inspection, identification, and marking for bolted connection parts operating in extreme temperatures from -200\u00b0C to +700\u00b0C. It ensures reliability in applications such as pressure vessels, boilers, and high-temperature machinery, supplementing standards like GB\/T 3098.1, GB\/T 3098.6, and DIN EN 10269.
