Iinkqubo ezahlukeneyo ezisemgangathweni zibonelela ngeendawo ezahlukeneyo zokusetyenziswa, kwaye ukugxila kwe-char yobunzima bepayipi akufani.
Namhlanje siza kuxoxa ngenkqubo esemgangathweni ye-EN ye-EN10220.
Isishwankathelo somgangatho we-EN 10220
EN 10220ngumgangatho waseYurophu wobungakanani kunye nokunyamezelana kwemibhobho yentsimbi engenamthungo nedibeneyo.
Umgangatho we-EN 10220 uneendlela ezahlukeneyo zokusetyenziswa kwaye usetyenziswa kakhulu kumashishini eoyile, igesi, iikhemikhali, ezokwakha kunye nezokucoca amanzi.
Umgangatho uquka ububanzi bangaphandle (OD) kunye nobukhulu bodonga (WT) lweepayipi zentsimbi, ubonelela ngezikhokelo ezicacileyo kunye neenkcukacha ezifanayo zoyilo kunye nokuveliswa kobunjineli ukuqinisekisa ukuhambelana kunye nokutshintshana kweemveliso zeepayipi eziveliswa ngabavelisi abahlukeneyo.
Iindlela Zokubala Ubunzima
Indlela yokubala ubunzima ngemitha nganye ngobude beyunithi inikwe kwi-EN 10220.
M=(DT)×Tx0.0246615
Mbubunzima ngeyunithi ubude kwi kg/m,
Dbububanzi obungaphandle obuchaziweyo kwi-mm,
Tbubukhulu bodonga obuchaziweyo nge-mm.
Le nto isekelwe kuxinano lwe-7.85 kg/dm3.(kg/dm3yiyunithi yoxinano, ii-cubic decimeters.)
Amaxabiso abaliweyo angasetyenziswa nakwiityhubhu ezinexabiso elahlukileyo loxinano, kodwa emva koko kufuneka aphindaphindwe ngenani le
1.015 yentsimbi engagqwaliyo ye-austenitic（Le nto isekelwe kubuninzi be-7.97 kg/dm3）.
0.985 yentsimbi engagqwali ye-ferritic kunye ne-martensitic（Le nto isekelwe kuxinano lwe-7.73 kg/dm3）.
Ubalo lunokwenziwa ngokusekelwe kumaxabiso oxinano olwahlulweyo kwiqela ngalinye leeklasi zentsimbi engagqwaliyo ezibonelelwe kwi-EN 10088-1.
Udidi lwe-EN 10220 Series
EN 10220ngokwezinga lomgangatho weepayipi kunye nezixhobo zazo. Kukho uthotho oluthathu.
uthotho 1: iidayamitha zangaphandle apho zonke izixhobo ezifunekayo ekwakheni iinkqubo zemibhobho zisemgangathweni;
uthotho 2: ububanzi bangaphandle apho zonke izixhobo zingafaniyo;
uthotho 3: iidayamitha zangaphandle apho zimbalwa kakhulu izixhobo ezisemgangathweni ezikhoyo.
Iitshathi zobunzima bepayipi ze-EN 10220 Series 1
I-OD yombhobho yolu ngcelele ilandela imigangatho yamazwe ngamazwe okanye yeshishini ngqo, kwaye imakethi inikezela ngezinto ezisemgangathweni ngokupheleleyo ezifana neeflanges, ii-couplings, kunye neengqiniba.
Olu hlengahlengiso olupheleleyo lwenza lula uyilo kunye nenkqubo yokufakela kwaye kunciphisa isidingo seendawo ezingezizo ezisemgangathweni kunye neendleko zokwenza ngokwezifiso.
Iitshathi zobunzima bepayipi ze-EN 10220 Series 2
Inxalenye ye-OD yolu hlobo lwemibhobho isemgangathweni, kodwa ayizizo zonke izixhobo ezisemgangathweni. Ezinye izixhobo ezisemgangathweni, ezifana neeflanges okanye iingqiniba, zinokufunyanwa, ngelixa ezinye iindawo zinokufuna ukwenziwa ngokwezifiso, oko kongeza kwiindleko kunye nobunzima beprojekthi.
Iitshathi zobunzima bepayipi ze-EN 10220 Series 3
Oku kudla ngokuba njalo ngobukhulu beepayipi ezithile okanye ezingaqhelekanga ezifuna inani elikhulu lezixhobo kunye nezinto ezenzelwe wena, nto leyo enyusa iindleko zokuyila nokuphumeza iprojekthi, kunye nokwandisa umjikelo wokuthenga kunye nokuvelisa.
Iitshati zoBunzima beMibhobho yoBukhulu boDonga 70 -100 mm
Kwiityhubhu ezinamacala amakhulu ezinobukhulu bodonga ukusuka kwi-70 mm ukuya kwi-100 mm, iimfuno zichazwe kwi-EN 10220, kwiTheyibhile 2.
Izixhobo zeetyhubhu zodonga ezinzima ezinobukhulu obuhambelana neTheyibhile 2 zisenokungafumaneki nokuba luluphi na uthotho olukwiTheyibhile 1 apho ububanzi obufanelekileyo bangaphandle bubelwe khona.
Singumvelisi kunye nomthengisi wemibhobho yentsimbi yekhabhoni edityanisiweyo ekumgangatho ophezulu evela eTshayina, kwaye sikwangumthengisi wemibhobho yentsimbi engenamthungo, sikunika uluhlu olubanzi lwezisombululo zemibhobho yentsimbi!
iithegi: en 10220, itshathi yobunzima bepayipi, uthotho 1, ababoneleli, abavelisi, iifektri, abathengisi besitokhwe, iinkampani, ukuthengisa ngobuninzi, thenga, ixabiso, ikowuteshini, ubuninzi, ukuthengiswa, ixabiso.
