I-EN 10216 uthotho lwemigangatho: Imigangatho ye-EU yeebhoyila, iityhubhu zomsi kunye neetyhubhu zeheater

Kwiminyaka yakutshanje, kunye nenkqubela phambili yoshishino, imfuno yemibhobho yentsimbi ekumgangatho ophezulu iqhubekile nokunyuka, ngakumbi kwimimandla yeebhoyila, iityhubhu zomsi, iityhubhu ze-superheater kunye ne-air preheater tubes. Ukuze kuqinisekiswe ukhuseleko, ukuqina kunye nokusebenza kwezi mveliso, i-EU iye yaqulunqa uluhlu lwemigangatho ye-EN 10216 ukucacisa iimfuno kunye nokusetyenziswa kwemibhobho yensimbi. Eli nqaku liza kugxininisa kwimigangatho emibini ebalulekileyo ye-EU, i-EN 10216-1 kunye ne-EN 10216-2, igxininise kwisicelo sabo, amabakala aphambili emibhobho yentsimbi kunye nezilumkiso xa usebenzisa.

Ukutolika okusemgangathweni: EN 10216-1 kunye ne-EN 10216-2

I-EN 10216-1 kunye ne-EN 10216-2 yimigangatho ye-EU yokwenza imibhobho yentsimbi kunye neemfuno zomgangatho, ngokukodwa kwiindidi ezahlukeneyo zemibhobho yentsimbi kunye neemeko zokusetyenziswa kwazo. I-EN 10216-1 ikakhulu ibandakanya iimfuno zokwenziwa kwemibhobho yentsimbi engenamthungo, ngakumbi kwizicelo ezinje ngeebhoyila zoxinzelelo oluphezulu kunye nemibhobho yokuhambisa ubushushu ephantsi kobushushu obuphezulu kunye neemeko zoxinzelelo oluphezulu. I-EN 10216-2 igxile kwimibhobho yentsimbi yealloy ethile, efana naleyo isetyenziswa ngokubanzi kumashishini amachiza kunye nombane. Le migangatho ichaza ukubunjwa kweekhemikhali, iipropathi zomatshini, ukunyamezelwa kobukhulu kunye nezinto zokuhlola eziyimfuneko zemibhobho yentsimbi ukuze kuqinisekiswe ukuthembeka kunye nokhuseleko lwemibhobho yentsimbi eveliswayo kwiindawo ezinzima ezifana nobushushu obuphezulu kunye noxinzelelo oluphezulu.

Usetyenziso oluphambili

Imibhobho yentsimbi eveliswe ngokwemigangatho yothotho lwe-EN 10216 isetyenziswa kakhulu kwibhoyila yamanzi kwibhoyibhobho, imibhobho yomsi, imibhobho yesifudumezi esikhulu, imibhobho yobushushu bomoya kunye nezinye iindawo. Le mibhobho yentsimbi idla ngokusetyenziselwa ukumelana nobushushu obuphezulu, iigesi ezidliwayo kunye neendawo zokusebenza ezinoxinzelelo oluphezulu. Ke ngoko, kufuneka babe namandla aphezulu, ukumelana nokugqwesa okugqwesileyo kunye nokuhamba kakuhle kwe-thermal.

Kwizixhobo zebhoyila, i-EN 10216 imibhobho yentsimbi yochungechunge isetyenziselwa imibhobho yamanzi kwibhoyila kunye nemibhobho yomsi ukuqhuba ubushushu kunye nokukhupha igesi yokukhupha. Imibhobho ye-Superheater kunye ne-air preheating pipes nazo ziyimimandla ebalulekileyo yesicelo solu luhlu lwemibhobho yentsimbi. Indima yabo kukuphucula ngokufanelekileyo ukusebenza kakuhle kwe-thermal ye-boilers kunye nokunciphisa ukusetyenziswa kwamandla.

Amanqanaba emibhobho yentsimbi eqhelekileyo

Kuluhlu lwemigangatho ye-EN 10216, amabanga aqhelekileyo wemibhobho yentsimbi abandakanya:P195, P235, P265, P195GH, P235GH, P265GH, 13CrMo4-5, 10CrMo9-10, njl.. Ezi zigaba zemibhobho yensimbi zinemichiza eyahlukeneyo kunye neempawu ezibonakalayo kwaye zifanelekile kwiindawo ezahlukeneyo zokusebenza. Ngokomzekelo, iipayipi zensimbi ze-P195GH kunye ne-P235GH zihlala zisetyenziselwa izixhobo zebhoyili, ngelixa i-13CrMo4-5 kunye ne-10CrMo9-10 zisetyenziswa kakhulu kwizixhobo zekhemikhali kunye nobushushu obuphezulu kunye neendawo zoxinzelelo oluphezulu.

Imiqathango yokusetyenziswa

Nangona imibhobho yentsimbi ye-EN 10216 inomsebenzi ogqwesileyo, ezinye izilumkiso kusafuneka zithathwe xa uzisebenzisa. Okokuqala, abasebenzisi kufuneka bakhethe ibakala elifanelekileyo lombhobho wensimbi ngokwendawo ethile yesicelo ukuqinisekisa ukusebenza ngokukhuselekileyo kwenkqubo yombhobho. Okwesibini, umbhobho wensimbi kufuneka uhlolwe rhoqo ngexesha lokusetyenziswa, ngokukodwa kwiqondo lokushisa eliphezulu kunye neendawo zoxinzelelo oluphezulu, kwaye ingqalelo kufuneka ihlawulwe ukuba ingaba umbhobho unobuqhophololo, ukuqhekeka okanye omnye umonakalo. Ekugqibeleni, ukwenzela ukwandisa ubomi benkonzo yombhobho wensimbi, ukucocwa rhoqo kunye nokugcinwa akufanele kuhoywe.

I-EN 10216-1 kunye ne-EN 10216-2 uluhlu lwemigangatho lubonelela ngeemveliso zemibhobho yentsimbi ekumgangatho ophezulu kwimveliso yemveliso, ukuqinisekisa ukhuseleko kunye nokuzinza kwezixhobo eziphambili ezifana nezibhobho, imibhobho yomsi, iityhubhu ze-superheater, njl.
