Ezimbonini zokwakha nezobunjiniyela, amazinga adlala indima ebalulekile ekuqinisekiseni ukuphepha, ukuthembeka kanye nekhwalithi. Indinganiso eyodwa eqashelwa kabanzi eYurophu yi-EN 10219, ehlanganisa izingxenye ezingenalutho ezakhiwe nge-welded. Phakathi kwamazinga ahlukahlukene achazwe kule ndinganiso, i-S235JRH iphawuleka kakhulu. Kule bhulogi, sizobheka kabanzi ukuthi yiniI-EN 10219 S235JRHizindlela, ukusetshenziswa kwayo, kanye nokubaluleka kwayo kumaphrojekthi okwakha anamuhla.
I-EN 10219 iyindinganiso yaseYurophu echaza izimo zokulethwa kobuchwepheshe zezingxenye ezingenalutho ezakhiwe ngesakhiwo ezihlanganisiwe ezibandayo. Lezi zingxenye zingaba yindilinga, isikwele noma unxande futhi zenziwe zibandayo ngaphandle kokwelashwa kokushisa okulandelayo. Lokhu kusho ukuthi izinto zigcina izakhiwo zazo zokuqala, okwenza zifanelekele ukusetshenziswa okubanzi kwesakhiwo. Indinganiso iqinisekisa ukuthi lezi zingxenye ezingenalutho zihlangabezana nezidingo ezithile mayelana nezakhiwo zemishini, ukwakheka kwamakhemikhali kanye nokubekezelelana kobukhulu.
I-S235JRH ibhekisela ebangeni elithile lensimbi elihambisana nezinga le-EN 10219. I-"S" ikhombisa ukuthi iyinsimbi yesakhiwo kanti i-"235" ikhombisa ukuthi impahla inamandla amancane okukhiqiza angama-megapascal angu-235 (MPa). I-"J" ikhombisa ukuthi insimbi ifanelekela ukushisela kanti i-"RH" ikhombisa ukuthi iyingxenye engenalutho. Lokhu kuhlanganiswa kwezakhiwo kwenza i-S235JRH ibe ukukhetha okuhle kwezinhlelo zokusebenza eziningi zesakhiwo.
Enye yezinzuzo eziyinhloko zokusebenzisa izingxenye ezingenalutho ze-S235JRH isilinganiso sayo samandla nesisindo. Inqubo yokwakha ebandayo ingadala izakhiwo ezilula kodwa eziqinile, inciphise kakhulu isisindo sonke sephrojekthi yesakhiwo noma yengqalasizinda. Lokhu kuwusizo ikakhulukazi ekusetshenzisweni lapho isisindo siyisici esibalulekile, njengamabhuloho, imibhoshongo nezakhiwo eziphakeme.
Ngaphezu kwalokho, ukuguquguquka kwezingxenye ezingenalutho ze-S235JRH kuzenza zifanelekele izinhlelo zokusebenza eziningi ezahlukene. Zingasetshenziswa ekwakhiweni kwamafreyimu, amakholomu kanye nemishayo, kanye nasekwenzeni ifenisha nezinye izingxenye zesakhiwo. Ikhono lokuxhunyelelwa ndawonye kalula landisa ukuguquguquka komklamo, okuvumela onjiniyela nabakhi bezakhiwo ukuthi bakhe izakhiwo ezintsha nezijabulisayo.
Esinye isici esibalulekile se-EN 10219 S235JRH ukuhambisana kwayo nezindinganiso zokuphepha nekhwalithi zaseYurophu. Ngokunamathela kule zindinganiso, abakhiqizi bangaqinisekisa ukuthi imikhiqizo yabo ihlangabezana nezidingo ezidingekayo zobuqotho besakhiwo nokusebenza. Lokhu akugcini nje ngokuthuthukisa ukuphepha kwesakhiwo sokugcina, kodwa futhi kwandisa ukuzethemba kwamakhasimende kanye nababambiqhaza ngekhwalithi yezinto ezisetshenziswayo.
Ngamafuphi, i-EN 10219 S235JRH iyindinganiso ebalulekile emkhakheni wokwakha nobunjiniyela, enikeza isiqondiso sokusetshenziswa kweisakhiwo esihlanganisiwe esenziwe ngobandayoizingxenye ezingenalutho. Inhlanganisela yayo yamandla, ukuguquguquka kanye nokuhambisana nezindinganiso zokuphepha kwenza kube ukukhetha okuhle kakhulu kwezicelo eziningi. Njengoba imboni yokwakha iqhubeka nokukhula, ukubaluleka kokuhambisana nalezi zindinganiso kuzokhula kuphela, kuqinisekiswe ukuthi izakhiwo zokwakha zihlala isikhathi eside ngenkathi kugcinwa ukuphepha nekhwalithi. Kungakhathaliseki ukuthi ungunjiniyela, umakhi noma umakhi, ukuqonda nokusebenzisa i-EN 10219 S235JRH kungayandisa kakhulu impumelelo yephrojekthi yakho.
