Lisebelisoa tsa tanka bakeng sa litanka tsa polokelo tsa cryogenic le litanka tsa polokelo tsa LPG

Joaloka mofani oa thepa ea nang le phihlelo ea lilemo tse 20, tanka ea Jianshen ha e na theknoloji e tsoetseng pele ea tlhahiso feela, empa hape e laola ka thata khetho ea lisebelisoa tse tala. Kajeno ke tla u bolella ka lisebelisoa tse tala tse sebelisoang ha ho etsoa tanka ea Jianshen. Thepa ea ka ntle ea silindara ealitanka tsa polokelo ea cryogenic (LO2, LCO2, LN2, tanka ea polokelo ea LAr, litanka tsa polokelo tsa LNG) le Litanka tsa polokelo ea LPG li entsoe ka poleiti ea tšepe ea Q345R, 'me nomoro e tloaelehileng ea Amerika ke SA516Gr.70.

SA516Gr.70 ke poleiti ea carbon steel bakeng sa likepe tsa khatello ea mocheso o mahareng le o tlase, o lumellanang le maemo a ASME. E le ho finyella litlhoko tse fapaneng tsa basebelisi le ho nolofatsa tsamaiso ea tlhahiso, litlhoko tsa S le P bakeng sa lihlopha tsa tšepe li arotsoe ka mekhahlelo e meraro: I, II, le III.

A516Gr70N e kopana le litlhoko tsa (ASME) ASTMA516 \/ A516M e tloaelehileng, 'me e finyella ka botlalo litlhoko tsa oli le khase tse nang le sebabole se phahameng le hydrogen content. Letlapa la tšepe le na le lintho tse fokolang tsa P le S, bohloeki bo phahameng, bo fokotsa sebabole le hydrogen corrosion, le ho fokotsa tlhokomelo ea lisebelisoa 2. Eketsa bophelo ba tšebeletso ea lisebelisoa.Letlapa la tšepe le na le litšobotsi tse latelang: ho hanyetsa phello e ntle, mocheso o tlase oa mocheso, ts'ebetso e ntle ea ho tjheseletsa, ho hanyetsa mokhathala o motle, ts'ebetso e ntle ea anti-layered spalling, micro alloying, bohloeki bo phahameng, k'habone e lekanang le k'habone, ho hanyetsa ka matla ho sebabole le hydrogen, e boetse e na le khanyetso e matla ea sulfide stress corrosion (SSCC), ho thatafala ha poleiti ea tšepe e ka laoloa, e na le ts'ebetso e ntle ea moqolo, e na le ts'ebetso e ntle ea moqolo. mamello ya dimensional le boleng ba bokahodimo.

Tanka ea polokelo ea cryogenic le tanka ea polokelo ea LPG e hlahisoang ke tanka ea Jianshen e sebelisang poleiti ea tšepe ea Q345r ha e na ts'ebetso e ntle ea kutu, empa hape ha e bonolo ho holofala, e na le ts'ebetso e matla ea ho hanyetsa, 'me e na le bophelo ba tšebeletso ea lilemo tse 20-30. Tanka ea Jianshen e fumaneha ka litanka tse otlolohileng kapa tse tšekaletseng tse nang le boholo bo fapaneng.
