Kumashishini okwakha kunye nobunjineli, imigangatho idlala indima ebalulekileyo ekuqinisekiseni ukhuseleko, ukuthembeka kunye nomgangatho. Omnye umgangatho owamkelwa ngokubanzi eYurophu yi-EN 10219, equka amacandelo angaphakathi adityanisiweyo adityanisiweyo. Phakathi kwamabanga ahlukeneyo achazwe kulo mgangatho, i-S235JRH ibaluleke kakhulu. Kule blog, siza kujonga ngakumbi ukuba yintoniEN 10219 S235JRHiindlela, ukusetyenziswa kwayo, nokubaluleka kwayo kwiiprojekthi zokwakha zale mihla.
I-EN 10219 ngumgangatho waseYurophu ochaza iimeko zonikezelo zobugcisa kumacandelo angaphakathi adityanisiweyo. La macandelo anokuba angqukuva, isikwere okanye uxande kwaye akhiwe ngokubanda ngaphandle konyango olulandelayo lobushushu. Oku kuthetha ukuba izinto eziphathekayo zigcina iimpawu zayo zangaphambili, okwenza ukuba zilungele uluhlu olubanzi lwezicelo zesakhiwo. Umgangatho uqinisekisa ukuba la macandelo angenanto ahlangabezana neemfuno ezithile malunga neempawu zoomatshini, ukwakheka kweekhemikhali kunye nokunyamezelwa kobukhulu.
I-S235JRH ibhekisela kwibakala elithile lentsimbi ehambelana nomgangatho we-EN 10219. I "S" ibonisa ukuba yintsimbi yesakhiwo kunye ne "235" ibonisa ukuba izinto eziphathekayo zinomlinganiselo omncinci wokuvelisa i-235 megapascals (MPa). I "J" ibonisa ukuba intsimbi ifanelekile kwi-welding kwaye "RH" ibonisa ukuba licandelo elingenanto. Olu luhlu lweepropati lwenza ukuba i-S235JRH ibe yinto efanelekileyo yokukhetha uluhlu olubanzi lwezicelo zesakhiwo.
Enye yeenzuzo eziphambili zokusebenzisa i-S235JRH amacandelo angenanto kumlinganiselo wayo wamandla ukuya kubunzima. Inkqubo yokubumba ebandayo inokudala izakhiwo ezikhaphukhaphu kodwa ezinamandla, ukunciphisa kakhulu ubunzima obupheleleyo besakhiwo okanye iprojekthi yeziseko. Oku kunenzuzo ngokukodwa kwizicelo apho ubunzima buyinto ebalulekileyo, njengamabhuloho, iinqaba kunye nezakhiwo eziphakamileyo.
Ukongeza, ukuguquguquka kwamacandelo angenanto e-S235JRH kubenza bafaneleke kuluhlu olubanzi lwezicelo. Zingasetyenziselwa ekwakhiweni kweefreyimu, iikholomu kunye nemiqadi, kunye nokuveliswa kwefenitshala kunye nezinye izinto zesakhiwo. Ukukwazi ukudityaniswa ngokulula kwandisa ukuguquguquka koyilo, kuvumela iinjineli kunye nabayili bezakhiwo ukuba benze izinto ezintsha kunye nezakhiwo ezithandekayo.
Enye inkalo ebalulekileyo ye-EN 10219 S235JRH kukuthotyelwa kwayo nokhuseleko lwaseYurophu kunye nemigangatho yomgangatho. Ngokuthobela lo mgangatho, abavelisi banokuqinisekisa ukuba iimveliso zabo zihlangabezana neemfuno eziyimfuneko zokunyaniseka kwesakhiwo kunye nokusebenza. Oku akugcini nje ukuphucula ukhuseleko lwesakhiwo sokugqibela, kodwa kwandisa ukuzithemba kwabathengi kunye nabachaphazelekayo kumgangatho wezinto ezisetyenzisiweyo.
Isishwankathelo, i-EN 10219 S235JRH ngumgangatho obalulekileyo kwicandelo lokwakha kunye nobunjineli, ebonelela ngesikhokelo sokusetyenziswakubanda kwakheka welded lwesakhiwoamacandelo angenanto. Ukudibanisa kwayo amandla, ukuguquguquka kunye nokuthotyelwa kwemigangatho yokhuseleko kwenza kube yinto ekhethekileyo yokukhetha uluhlu olubanzi lwezicelo. Njengoko ishishini lokwakha liqhubeka nokukhula, ukubaluleka kokuthobela imigangatho enjalo kuya kwanda kuphela, kuqinisekisa ukuba izakhiwo zokwakha zihlala ixesha elide ngelixa zigcina ukhuseleko kunye nomgangatho. Nokuba uyinjineli, uyingcibi okanye unokontraka, uyayiqonda kwaye usebenzisa i-EN 10219 S235JRH inokwandisa kakhulu impumelelo yeprojekthi yakho.
