Umbhobho wentsimbi ongenamthungo waqengqelekaEN10210 S355J2Hngumbhobho wentsimbi yesakhiwo esiphezulu, esetyenziswa ngokuqhelekileyo kwiinkalo ezahlukeneyo zoshishino kunye neeprojekthi zobunjineli. Oku kulandelayo kukusetyenziswa kwayo okuphambili kunye nemiba efuna ukuhoywa xa uthenga:
Ishishini kunye nokusetyenziswa:
Ubunjineli boyilo kunye nobunjineli bolwakhiwo:
Isetyenziselwa iifreyimu zesakhiwo sensimbi, iibhuloho, iinqaba, njl.
Yenza iikholomu ezithwala imithwalo, imiqadi, iitrasi kunye nezinye iindawo zesakhiwo.
Ukwenziwa koomatshini:
Isetyenziselwa ukwenza izibiyeli, iifreyimu kunye neenxalenye zezixhobo zoomatshini.
Ukubandakanya izixhobo ezithwala umthwalo ezifana neekhreyini kunye neenkqubo zokuhambisa.
Ishishini lamandla:
Isetyenziselwa iinqaba zamandla omoya, imibhobho ye-oyile nerhasi kunye nezinye izibonelelo ezinxulumene namandla.
Iinqanawa kunye nobunjineli baselwandle:
Isetyenziswa kwiindawo zesakhiwo samaqonga aphesheya kunye neenqanawa.
Izilumkiso xa uthenga:
Izinto kunye nomgangatho:
I-S355 ithetha amandla esivuno ngama-355 MPa;
I-J2 ithetha ukuqina kwempembelelo kwi -20°C ihlangabezana neemfuno;
H ithetha intsimbi engenanto.
Imilinganiselo kunye nokunyamezela:
Jonga ukuba iinkcukacha zedayamitha yangaphandle, ubukhulu bodonga kunye nobude ziyahlangabezana neemfuno zoyilo lweprojekthi.
Qinisekisa ukuba ukunyamezela komgangatho kungaphakathiEN 10210umgangatho.
Amaxwebhu esiqinisekiso somgangatho (MTC, 3.1/3.2):
Umvelisi kufuneka anikeze ngamaxwebhu esiqinisekiso somgangatho ngokuhambelana ne-EN 10204, kubandakanywa ukubunjwa kweekhemikhali, iipropati zomatshini kunye neengxelo zokuvavanya ezingonakalisi.
Ubulunga bomphezulu kunye nokubonwa kwesiphene:
Umphezulu kufuneka ungabi naziphene ezicacileyo ezifana nokuqhekeka, i-rust, indentations, njl.
Khangela ukuba iphumelele uvavanyo olungonakalisi (njengovavanyo lwe-ultrasonic), ngakumbi kwiindawo eziphambili ezithwala umthwalo.
Ukumelana nokubola kunye nonyango lwasemva konyango:
Ukuba isetyenziswe kwindawo enobungozi, kufuneka kuqinisekiswe ukuba i-coating okanye i-galvanizing iyafuneka.
Kwakhona kunokwenzeka ukuba kuqwalaselwe ukuba unyango lobushushu (njengesiqhelo okanye ukufudumala) luyafuneka ukuze kuphuculwe ukusebenza.
Iziqinisekiso zomboneleli:
Khetha ababoneleli abanegama elihle kunye nomgangatho ozinzile ukuqinisekisa ukuhambelana kwemveliso.
Kwimiyalelo yomthamo omkhulu, umthamo wemveliso yefektri unokuhlolwa kwisiza.
Ulungiselelo kunye nokuhanjiswa:
Qinisekisa ukuba indlela yokuthutha inokuphepha ukuguqulwa okanye umonakalo womphezulu wombhobho.
Ngokukodwa kwimibhobho emide, kuyimfuneko ukuhlawula ingqalelo ekhethekileyo kwiindlela zokupakisha kunye nokulungisa.
Ixabiso kunye nexesha lokuhambisa:
Nika ingqalelo ekuguquguqukeni kwamaxabiso ezinto ezikrwada kwimarike kwaye utshixe amaxabiso okuthenga afanelekileyo kwangexesha.
Sula umjikelo wonikezelo ukuthintela ukulibaziseka ngenxa yenkqubela phambili yeprojekthi.
Njengoko ukuphela konyaka kusondela, iindleko zokuthumela zinokwenyuka. Nceda uqinisekise umhla wokuziswa kwaye ulawule iindleko.
