Uthotho lwemigangatho ye-EN 10216: Imigangatho ye-EU yeebhoyila, iityhubhu zomsi kunye neetyhubhu ze-superheater

Kwiminyaka yakutshanje, ngokuhambela phambili kwezoshishino, imfuno yeepayipi zentsimbi ezikumgangatho ophezulu iqhubekile nokukhula, ngakumbi kwicandelo leebhoyila, iityhubhu zomsi, iityhubhu ze-superheater kunye neetyhubhu ze-air preheater. Ukuze kuqinisekiswe ukhuseleko, ukuqina kunye nokusebenza kwezi mveliso, i-EU iye yaqulunqa uthotho lwemigangatho ye-EN 10216 ukucacisa iimfuno kunye nokusetyenziswa kweepayipi zentsimbi. Eli nqaku liza kugxila kwimigangatho emibini ebalulekileyo ye-EU, i-EN 10216-1 kunye ne-EN 10216-2, igxile ekusetyenzisweni kwayo, amanqanaba aphambili eepayipi zentsimbi kunye nezilumkiso xa uzisebenzisa.

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

I-EN 10216-1 kunye ne-EN 10216-2 ziimigangatho ze-EU zokwenza imibhobho yentsimbi kunye neemfuno zomgangatho, ngokukodwa kwiintlobo ezahlukeneyo zemibhobho yentsimbi kunye neemeko zokusetyenziswa kwayo. I-EN 10216-1 ikakhulu ibandakanya iimfuno zokwenza imibhobho yentsimbi engenamthungo, ngakumbi kwizicelo ezifana neebhoyila ezinoxinzelelo oluphezulu kunye nemibhobho yokudlulisa ubushushu ejongene nobushushu obuphezulu kunye neemeko zoxinzelelo oluphezulu. I-EN 10216-2 igxile kwimibhobho ethile yentsimbi ye-alloy, efana naleyo isetyenziswa kakhulu kumashishini eekhemikhali kunye namandla. Le migangatho ichaza ukwakheka kweekhemikhali, iimpawu zoomatshini, ukunyamezelana kobukhulu kunye nezinto ezifunekayo zokuhlola imibhobho yentsimbi ukuqinisekisa ukuthembeka kunye nokhuseleko lwemibhobho yentsimbi eveliswayo kwiindawo ezinzima ezifana nobushushu obuphezulu kunye noxinzelelo oluphezulu.

Iindlela eziphambili zokusetyenziswa

Iipayipi zentsimbi eziveliswa ngokwemigangatho yochungechunge lwe-EN 10216 zisetyenziswa kakhulu kwiipayipi zamanzi ebhoyila, iipayipi zomsi, iipayipi ze-superheater, iipayipi zokufudumeza umoya kunye nezinye iindawo. Ezi pipes zentsimbi zihlala zisetyenziselwa ukumelana nobushushu obuphezulu, iigesi ezirhabaxa kunye neendawo zokusebenza ngomphunga oxinzelelweyo ophezulu. Ke ngoko, kufuneka zibe namandla aphezulu, zikwazi ukumelana nokugqwala okugqwesileyo kunye nokuqhuba kakuhle kobushushu.

Kwizixhobo zebhoyila, imibhobho yentsimbi yochungechunge lwe-EN 10216 isetyenziselwa imibhobho yamanzi ebhoyila kunye nemibhobho yomsi ukuqhuba ubushushu nokukhupha igesi yokukhupha umoya. Imibhobho ye-Superheater kunye nemibhobho yokufudumeza umoya kwangaphambili nazo ziindawo ezibalulekileyo zokusetyenziswa kolu luhlu lwemibhobho yentsimbi. Indima yazo kukuphucula ngokufanelekileyo ukusebenza kakuhle kobushushu beebhoyila kunye nokunciphisa ukusetyenziswa kwamandla.

Amanqanaba epayipi yentsimbi eqhelekileyo

Kuluhlu lwemigangatho ye-EN 10216, amanqanaba eepayipi zentsimbi eziqhelekileyo aquka:P195, P235, P265, P195GH, P235GH, P265GH, 13CrMo4-5, 10CrMo9-10, njl.Ezi ntlobo zeepayipi zentsimbi zinemilo eyahlukeneyo yeekhemikhali kunye neempawu zomzimba kwaye zifanelekile kwiindawo ezahlukeneyo zokusebenza. Umzekelo, iipayipi zentsimbi ze-P195GH kunye ne-P235GH zihlala zisetyenziswa kwizixhobo zebhoyila, ngelixa i-13CrMo4-5 kunye ne-10CrMo9-10 zisetyenziswa kakhulu kwizixhobo zeekhemikhali kunye neendawo ezinobushushu obuphezulu kunye noxinzelelo oluphezulu.

Amanyathelo okusebenzisa

Nangona imibhobho yentsimbi yochungechunge lwe-EN 10216 isebenza kakuhle kakhulu, kufuneka kuthathwe amanyathelo athile okhuseleko xa uyisebenzisa. Okokuqala, abasebenzisi kufuneka bakhethe umgangatho wemibhobho yentsimbi ofanelekileyo ngokwendawo ethile yokusetyenziswa ukuqinisekisa ukusebenza ngokukhuselekileyo kwenkqubo yemibhobho. Okwesibini, umbhobho wentsimbi kufuneka uhlolwe rhoqo ngexesha lokusetyenziswa, ingakumbi kwiindawo ezinobushushu obuphezulu kunye noxinzelelo oluphezulu, kwaye kufuneka kuqwalaselwe ukuba ingaba umbhobho unomhlwa, imifantu okanye omnye umonakalo. Okokugqibela, ukuze kwandiswe ubomi benkonzo yombhobho wentsimbi, ukucoca nokulungisa rhoqo akufanele kungananzwa.

Uthotho lwemigangatho ye-EN 10216-1 kunye ne-EN 10216-2 lubonelela ngeemveliso zemibhobho yentsimbi ekumgangatho ophezulu kwimveliso yemizi-mveliso, luqinisekisa ukhuseleko kunye nokuzinza kwezixhobo ezibalulekileyo ezifana neebhoyila, imibhobho yomsi, iityhubhu ze-superheater, njl. Ngokulandela le migangatho, ukusebenza kakuhle kwezixhobo kunokwandiswa kwaye ukusebenza okuqhubekayo nokuzinzileyo kwemveliso yemizi-mveliso kunokuqinisekiswa.
