Kwimizi-mveliso yokwakha nobunjineli, imigangatho idlala indima ebalulekileyo ekuqinisekiseni ukhuseleko, ukuthembeka kunye nomgangatho. Omnye umgangatho owaziwayo eYurophu yi-EN 10219, egubungela iindawo ezingenanto ezakhiwe ngentsimbi ebandayo. Phakathi kwamanqanaba ahlukeneyo achazwe kulo mgangatho, i-S235JRH ibaluleke kakhulu. Kule blog, siza kujonga ngokusondeleyo okoEN 10219 S235JRHiindlela zayo, ukusetyenziswa kwayo, kunye nokubaluleka kwayo kwiiprojekthi zokwakha zanamhlanje.
I-EN 10219 ngumgangatho waseYurophu ochaza iimeko zobuchwephesha zokuhanjiswa kwezixhobo ezidityanisiweyo ezakhiwe ngokubandayo. Ezi zixhobo zinokuba zingqukuva, zisikwere okanye zibe yingxande kwaye zenziwe ngokubandayo ngaphandle konyango lobushushu olulandelayo. Oku kuthetha ukuba izinto zigcina iimpawu zazo zokuqala, nto leyo eyenza zifaneleke kwiintlobo ngeentlobo zezicelo zezakhiwo. Umgangatho uqinisekisa ukuba ezi zixhobo zingenazo zihlangabezana neemfuno ezithile malunga neempawu zoomatshini, ukwakheka kweekhemikhali kunye nokunyamezelana kobukhulu.
I-S235JRH ibhekisa kudidi oluthile lwentsimbi oluhambelana nomgangatho we-EN 10219. I-"S" ibonisa ukuba yintsimbi yolwakhiwo kwaye i-"235" ibonisa ukuba izinto zinamandla amancinci okuvelisa angama-235 megapascals (MPa). I-"J" ibonisa ukuba intsimbi ifanelekile ukuwelda kwaye i-"RH" ibonisa ukuba yinxalenye engenanto. Olu dibaniso lweempawu lwenza i-S235JRH ibe lukhetho olufanelekileyo kwiintlobo ngeentlobo zezicelo zolwakhiwo.
Enye yezona nzuzo ziphambili zokusebenzisa iindawo ezingenanto ze-S235JRH ngumlinganiselo wayo wamandla nobunzima. Inkqubo yokwenza ubanda ingadala izakhiwo ezilula kodwa ezomeleleyo, nto leyo enciphisa kakhulu ubunzima besakhiwo okanye iprojekthi yeziseko zophuhliso. Oku kuluncedo ngakumbi kwizicelo apho ubunzima buyinto ebalulekileyo, njengeebhulorho, iinqaba kunye nezakhiwo eziphakamileyo.
Ukongeza, ukuguquguquka kweendawo ezingenanto ze-S235JRH kuzenza zilungele uluhlu olubanzi lwezicelo. Zingasetyenziswa ekwakheni izakhelo, iikholamu kunye neebhari, kunye nokwenza ifenitshala kunye nezinye izinto zokwakha. Amandla okudityaniswa ngokulula kwandisa ukuguquguquka koyilo, okuvumela iinjineli kunye nabayili bezakhiwo ukuba benze izakhiwo ezintsha nezithandekayo.
Enye into ebalulekileyo ye-EN 10219 S235JRH kukuthobela kwayo imigangatho yokhuseleko kunye nomgangatho waseYurophu. Ngokulandela le migangatho, abavelisi banokuqinisekisa ukuba iimveliso zabo ziyahlangabezana neemfuno ezifunekayo zokuthembeka kwesakhiwo kunye nokusebenza. Oku akuphuculi nje kuphela ukhuseleko lwesakhiwo sokugqibela, kodwa kwandisa ukuzithemba kwabathengi kunye nabachaphazelekayo kumgangatho wezixhobo ezisetyenzisiweyo.
Ngamafutshane, i-EN 10219 S235JRH ngumgangatho obalulekileyo kwicandelo lokwakha nobunjineli, obonelela ngesikhokelo sokusetyenziswaisakhiwo esidityanisiweyo esenziwe ngokubandayoiindawo ezingenanto. Ukudibana kwayo namandla, ukuguquguquka kunye nokuthobela imigangatho yokhuseleko kwenza ukuba ibe lukhetho oluhle kakhulu kwiintlobo ngeentlobo zezicelo. Njengoko ishishini lokwakha liqhubeka nokutshintsha, ukubaluleka kokuthobela imigangatho enjalo kuya kwanda kuphela, kuqinisekisa ukuba izakhiwo zokwakha zihlala ixesha elide ngelixa kugcinwa ukhuseleko kunye nomgangatho. Nokuba ungunjineli, umyili wezakhiwo okanye umakhi, ukuqonda nokusebenzisa i-EN 10219 S235JRH kunokunyusa kakhulu impumelelo yeprojekthi yakho.
