Iinkqubo ezahlukeneyo ezisemgangathweni zibonelela ngemida eyahlukeneyo yesicelo, kwaye ugxininiso lombhobho lobunzima alufani.
Namhlanje siza kuxubusha inkqubo ye-EN ye-EN10220.
Isishwankathelo somgangatho we-EN 10220
EN 10220ngumgangatho waseYurophu wemilinganiselo kunye nokunyamezela imibhobho yentsimbi engenamthungo kunye newelding.
Umgangatho we-EN 10220 unoluhlu olubanzi lwezicelo kwaye usetyenziswa ikakhulu kwi-oyile, igesi, imichiza, ulwakhiwo, kunye namashishini okucoca amanzi.
Umgangatho uquka ububanzi obungaphandle (OD) kunye nobukhulu bodonga (WT) lwemibhobho yensimbi, ukubonelela ngokucacileyo izikhokelo kunye neenkcukacha ezifanayo zoyilo lobunjineli kunye nokuveliswa ukuqinisekisa ukuhambelana kunye nokutshintshisana kweemveliso zepayipi eziveliswa ngabavelisi abahlukeneyo.
Iindlela zokubala ubunzima
Indlela yokubala ubunzima ngemitha nganye ngobude beyunithi inikwe kwi-EN 10220.
M=(DT)×Tx0.0246615
Mbubunzima ngeyunithi yobude ngekg/m,
Dsisidayamitha sangaphandle esixeliweyo kwi mm,
Tbubunzima obuxeliweyo bodonga kwi-mm.
Lo mbandela usekelwe kubuninzi be-7.85 kg / dm3.(kg/dm3yiyunithi yoxinano, cubic decimeters.)
Amaxabiso abalwayo anokusetyenziswa kwityhubhu enamaxabiso ahlukeneyo oxinaniso, kodwa kufuneka aphindaphindwe ngomlinganiselo we
I-1.015 ye-austenitic stainless steel (Le nto isekelwe kubuninzi be-7.97 kg / dm3）
I-0.985 yentsimbi ye-ferritic kunye ne-martensitic stainless (Le nto isekelwe kubuninzi be-7.73 kg / dm3）
Izibalo zingenziwa ngokusekelwe kumaxabiso ahlukeneyo oxinaniso kwiqela ngalinye lamabakala ensimbi engenasici anikezelwe kwi-EN 10088-1.
UHlelo lwe-EN 10220 Series
EN 10220ngokwenqanaba lomgangatho wemibhobho kunye nezixhobo zabo.Kukho uthotho oluthathu.
uchungechunge 1: iidamitha zangaphandle apho zonke izixhobo ezifunekayo ekwakhiweni kweenkqubo zombhobho zisemgangathweni;
uchungechunge 2: iidamitha zangaphandle ezingezizo zonke izincedisi ezisemgangathweni;
series 3: ngaphandle idayamitha apho zimbalwa izincedisi emgangathweni ezikhoyo.
Iitshathi zobunzima bombhobho EN 10220 Series 1
I-OD yombhobho yolu luhlu ilandela imigangatho yamazwe ngamazwe okanye yoshishino ngokuchanekileyo, kwaye imarike inikezela ngokufakela okusemgangathweni okusemgangathweni okufana neeflange, ukudityaniswa, kunye neengqiniba.
Olu lungelelwaniso lupheleleyo lwenza lula uyilo kunye nenkqubo yofakelo kwaye lunciphise imfuno yamalungu angengomgangatho kunye neendleko zokwenza ngokwezifiso.
Iitshathi zobunzima bombhobho EN 10220 Series 2
Inxalenye ye-OD yolu hlobo lwemibhobho isemgangathweni, kodwa ayizizo zonke izixhobo ezisemgangathweni.Ezinye izixhobo ezisemgangathweni, ezifana neeflange okanye i-elbows, zinokufumaneka, ngelixa ezinye iindawo zingadinga ukulungiswa, ukongeza kwiindleko kunye nobunzima beprojekthi.
Iitshathi zobunzima bombhobho EN 10220 Series 3
Oku kudla ngokubakho ngobungakanani obucacileyo okanye obungavumelekanga bombhobho odinga inani elikhulu lezinto zokufakelwa ngokwezifiso kunye namacandelo, ukuphakamisa iindleko zokuyila nokuphumeza iprojekthi, kunye nokwandisa umjikelo wokuthengwa kunye nokuvelisa.
Iitshathi zobunzima bombhobho woButyebi beendonga 70 -100 mm
Kwiityhubhu ezinodonga olungqingqwa kunye nobukhulu bodonga ukusuka kwi-70 mm ukuya kwi-100 mm, iimfuno zichazwe kwi-EN 10220, iThebhile 2.
Izixhobo zeetyhubhu ezinzima zodonga ezinobungakanani ngokuhambelana neThebhile 2 ayinakufumaneka kungakhathaliseki ukuba uchungechunge olukwiThebhile 1 apho i-diameter yangaphandle echaphazelekayo yabelwe khona.
Singumvelisi wemibhobho yentsimbi yekhabhoni ekumgangatho ophezulu odityanisiweyo kunye nomthengisi ovela eChina, kunye nesitokhwe semibhobho yentsimbi engenamthungo, ekunika uluhlu olubanzi lwezisombululo zemibhobho yentsimbi!
