Welded Carbon Steel API 650 Tanks: I-Standard yokugcina emoyeni
Emikhakheni yehlelo lamandla nelamakhemikhali emhlabeni wonke, isezingeni le-API 650 yiyona eyinhloko eqondisayo ekwakhiweni, ekwenziweni, nasekufakweni kwamathangi ensimbi eqinile ashiselelwe. Lawa mathangi enziwe ukuze agcine izinto ezinjengamafutha aluhlaza, uphethiloli, amakhemikhali, namanzi akhiqizwayo ngaphansi kwengcindezi yangaphakathi eseduze namazinga omoya.
1. Yini Isizinga Se-API 650?
Isizinga se-American Petroleum Institute (API) 650 sihlanganisa izidingo zamathangi agciniwe aqondile, ayindilinga, angaphezulu komhlaba, avaliwe avulekile, ashiselelwe.
● Ingcindezi Yokuklama: Kuhloselwe amathangi anengcindezi yangaphakathi engadluli ku-2.5 PSI.
● Ibanga Lokushisa: Kuvame ukusetshenziselwa izinsizakalo ezifika ku-93°C (200°F).
● Ukwethembeka Kwempahla: Kugxilwe kumapuleti ensimbi eqinile ahlinzeka ngamandla aphezulu okudonsa nokushiselwa okuhle ekwakhiweni okukhulu ensimini.
2. Kungani Insimbi Eqinile Yamathangi Ashiselelwe?
Insundu yensimbi iseyona into eyinhloko yamathangi e-API 650 ngenxa yokulinganisela kwayo kwezindleko nokusebenza kahle kwezobuchwepheshe.
● Ubuqotho besakhiwo: Insundu yensimbi inikeza ukuguquguquka okudingekayo ukubekezelela imithwalo yokuzamazama komhlaba kanye nomfutho woketshezi wangaphakathi ematankini angaphezu kuka-50,000 $m^3$.
● Ukuhlanganiswa emkhakheni: Ngokungafani nezinye izinsimbi, insimbi yekhabhoni ihlanganiswa kalula ezimweni ezahlukahlukene zemvelo, okwenza ibe yinhle kakhulu emaphrojekthi akhiwe emkhakheni.
● Ukuhambisana nokugqoka: Ngenkathi insimbi yekhabhoni ithambekele ekugqwaleni, isebenza njengesisekelo esihle sokugqoka okuthuthukisiwe njenge-Glass-Fused-to-Steel noma i-Epoxy, enikeza ukumelana nokugqwala okukhethekile.
3. Ukuqhathaniswa kwezici zobuchwepheshe
Isici | API 650 Welded Steel Tank | Concrete Tank (Prestressed/Reinforced) |
Ukuhlanganiswa Kwezinto | Carbon steel (A36, A516 grades) | Ikhonkolo enensimbi ye-rebar noma intambo yokuprestress |
Indlela Yokwakha | Ukuhlanganisa ezindaweni zokwakha iziqephu ezisikwe efektri | Ukufakwa okwenziwe endaweni, okwenziwe ngaphambili, noma ukufafazwa kwe-shotcrete |
Isimo Sokusebenzisa Esivamile | Uwoyela, igesi, amakhemikhali, namanzi ezimboni | Amanzi okuphuza, imisele kamasipala, nokuhlanjululwa kwamanzi olwandle |
Ukuthola ukuvuza | Kuphezulu (Ukuhlolwa kwe-X-ray/Vacuum kwamalwelwe) | Kulinganiselwe (Ukuhlolwa okubonakalayo nokwe-hydrostatic) |
Ukusebenza ngokuzamazama komhlaba | Kuphezulu (Impahla eqinile imunca amandla) | Kulinganiselwe (Impahla eyaphukayo; idinga ukuklama okukhethekile) |
Ukunwebeka okushisayo | Isilinganiso esiphezulu; sidinga ukuxhumana okuguquguqukayo | Isilinganiso esiphansi; sivame ukuhlanganisa ukushisa |
4. Izakhiwo eziyinhloko zokuklama
Ukuze kuqinisekiswe impilo yesevisi yeminyaka engama-30+, ama-tank we-API 650 ahlanganisa izinto ezithile zokwakha:
● Ukwakhiwa Kwe-Shell: Ukubala ububanzi be-plate ngokusekelwe kumthamo othile wamanzi kanye nengcindezi evunyelwe yensimbi.
● Izinhlobo Zezindonga: Izinketho zifaka phakathi izindonga ezimile, izindonga ze-dome, noma izindonga eziphakathi ukuze kuncishiswe ukulahleka kwe-vapor.
● Isisekelo: Izindonga ezinzima zekhonkolo noma amaphakethe amatshe aphukile aklanyelwe ukweseka umthwalo omkhulu we-static we-tank ephelele.
5. Ukugcinwa Nokuhambisana
Amathangi e-API 650 adinga uhlelo oluqinile lokuhlola, oluvame ukulandela imihlahlandlela ye-API 653 yokulungiswa, ukuguqulwa, nokwakhiwa kwamathangi.
● Ukuvikelwa kwe-Cathodic: Kusetshenziselwa ukuvimbela ukugqwala ohlangothini lwenhlabathi ezansi kwethangi.
● Ukuvalwa Kwesibili: Ukusetshenziswa kwamadike noma izendlalelo ukuqinisekisa ukuphepha kwemvelo uma kwenzeka ukuvuza.
Amathangi e-carbon steel API 650 aboshwe ayisisekelo sokugcina izimpahla ezinkulu. Ngenkathi i-Center Enamel igxile kumathangi aboshwe e-Glass-Fused-to-Steel anokumelana nokugqwala okuhle nokuhanjiswa okusheshayo, ukuqonda i-API 650 welded standard kubalulekile kubanjiniyela abaphatha izikhungo zokugcina uphethiloli nezimboni zamakhemikhali ezinamandla aphezulu.
